As much as\nwas possible, this module acts as a passive pass-through to Gnuplot, thus making\navailable the full power and flexibility of the Gnuplot backend. Gnuplot is\ndescribed in great detail at its upstream website: L\u003chttp://www.gnuplot.info\u003e.\n\nThe main subroutine that C\u003cPDL::Graphics::Gnuplot\u003e exports is C\u003cplot()\u003e. A call\nto C\u003cplot()\u003e looks like\n\n plot(plot_options,\n      curve_options, data, data, ... ,\n      curve_options, data, data, ... );\n\n=head2 Options arguments\n\nEach set of options is a hash that can be passed inline or as a hashref: both\nC\u003cplot( title =E\u003cgt\u003e 'Fancy plot!', ... )\u003e and C\u003cplot( {title =E\u003cgt\u003e 'Another fancy\nplot'}, ...)\u003e work. The plot options I\u003cmust\u003e precede all the curve options.\n\nThe plot options are parameters that affect the whole plot, like the title of\nthe plot, the axis labels, the extents, 2d/3d selection, etc. All the plot\noptions are described below in L\u003c/\"Plot options\"\u003e.\n\nThe curve options are parameters that affect only one curve in particular. Each\ncall to C\u003cplot()\u003e can contain many curves, and options for a particular curve\nI\u003cprecede\u003e the data for that curve in the argument list. Furthermore, I\u003ccurve\noptions are all cumulative\u003e. So if you set a particular style for a curve, this\nstyle will persist for all the following curves, until this style is turned\noff. The only exception to this is the C\u003clegend\u003e option, since it's very rarely\na good idea to have multiple curves with the same label. An example:\n\n plot( with =\u003e 'points', $x, $a,\n       y2   =\u003e 1,        $x, $b,\n       with =\u003e 'lines',  $x, $c );\n\nThis plots 3 curves: $a vs. $x plotted with points on the main y-axis (this is\nthe default), $b vs. $x plotted with points on the secondary y axis, and $c\nvs. $x plotted with lines also on the secondary y axis. All the curve options\nare described below in L\u003c/\"Curve options\"\u003e.\n\n=head2 Data arguments\n\nFollowing the curve options in the C\u003cplot()\u003e argument list is the actual data\nbeing plotted. Each output data point is a tuple whose size varies depending on\nwhat is being plotted. For example if we're making a simple 2D x-y plot, each\ntuple has 2 values; if we're making a 3d plot with each point having variable\nsize and color, each tuple has 5 values (x,y,z,size,color). In the C\u003cplot()\u003e\nargument list each tuple element must be passed separately. If we're making\nanything fancier than a simple 2D or 3D plot (2- and 3- tuples respectively)\nthen the C\u003ctuplesize\u003e curve option I\u003cmust\u003e be passed in. Furthermore, PDL\nthreading is active, so multiple curves can be plotted by stacking data inside\nthe passed-in piddles. When doing this, multiple sets of curve options can be\npassed in as multiple hashrefs preceding the data itself in the argument\nlist. By using hashrefs we can make clear which option corresponds to which\nplot. An example:\n\n my $pi    = 3.14159;\n my $theta = zeros(200)-\u003exlinvals(0, 6*$pi);\n my $z     = zeros(200)-\u003exlinvals(0, 5);\n\n plot( '3d' =\u003e 1, title =\u003e 'double helix',\n\n       { with =\u003e 'points pointsize variable pointtype 7 palette', tuplesize =\u003e 5,\n         legend =\u003e 'spiral 1' },\n       { legend =\u003e 'spiral 2' },\n\n       # 2 sets of x, 2 sets of y, single z\n       PDL::cat( cos($theta), -cos($theta)),\n       PDL::cat( sin($theta), -sin($theta)),\n       $z,\n\n       # pointsize, color\n       0.5 + abs(cos($theta)), sin(2*$theta) );\n\nThis is a 3d plot with variable size and color. There are 5 values in the tuple,\nwhich we specify. The first 2 piddles have dimensions (N,2); all the other\npiddles have a single dimension. Thus the PDL threading generates 2 distinct\ncurves, with varying values for x,y and identical values for everything else. To\nlabel the curves differently, 2 different sets of curve options are given. Since\nthe curve options are cumulative, the style and tuplesize needs only to be\npassed in for the first curve; the second curve inherits those options.\n\n\n=head3 Implicit domains\n\nWhen a particular tuplesize is specified, PDL::Graphics::Gnuplot will attempt to\nread that many piddles. If there aren't enough piddles available,\nPDL::Graphics::Gnuplot will throw an error, unless an implicit domain can be\nused. This happens if we are I\u003cexactly\u003e 1 or 2 piddles short (usually when\nmaking 2D and 3D plots respectively).\n\nWhen making a simple 2D plot, if exactly 1 dimension is missing,\nPDL::Graphics::Gnuplot will use C\u003csequence(N)\u003e as the domain. This is why code\nlike C\u003cplot(pdl(1,5,3,4,4) )\u003e works. Only one piddle is given here, but a\ndefault tuplesize of 2 is active, and we are thus exactly 1 piddle short. This\nis thus equivalent to C\u003cplot( sequence(5), pdl(1,5,3,4,4) )\u003e.\n\nIf plotting in 3d, an implicit domain will be used if we are exactly 2 piddles\nshort. In this case, PDL::Graphics::Gnuplot will use a 2D grid as a\ndomain. Example:\n\n my $xy = zeros(21,21)-\u003endcoords - pdl(10,10);\n plot('3d' =\u003e 1,\n       with =\u003e 'points', inner($xy, $xy));\n\nHere the only given piddle has dimensions (21,21). This is a 3D plot, so we are\nexactly 2 piddles short. Thus, PDL::Graphics::Gnuplot generates an implicit\ndomain, corresponding to a 21-by-21 grid.\n\nNote that this logic doesn't look at whether a 2D or 3D plot is being made. It\ncan make sense to have a 2D implicit domain when making 2D plots. For example,\none can be plotting a color map:\n\n my $xy = zeros(21,21)-\u003endcoords - pdl(10,10);\n my $z = inner($xy, $xy);\n plot(title  =\u003e 'Heat map',\n      tuplesize =\u003e 3, with =\u003e 'image', $z*2);\n\nThis is the same example as in the Synopsis, but plotted without '3d' =\u003e 1; the\noutput is very similar.\n\nAlso note that the C\u003ctuplesize\u003e curve option is independent of implicit domains.\nThis option specifies not how many data piddles we have, but how many values\nrepresent each data point. For example, if we want a 2D plot with varying colors\nplotted with an implicit domain, set C\u003ctuplesize\u003e to 3 as before, but pass in\nonly 2 piddles (y, color).\n\nOne thing to watch out for it to make sure PDL::Graphics::Gnuplot doesn't get\nconfused about when to use implicit domains. For example, C\u003cplot($a,$b)\u003e is\ninterpreted as plotting $b vs $a, I\u003cnot\u003e $a vs an implicit domain and $b vs an\nimplicit domain. If 2 implicit plots are desired, add a separator:\nC\u003cplot($a,{},$b)\u003e. Here C\u003c{}\u003e is an empty curve options hash. If C\u003c$a\u003e and C\u003c$b\u003e\nhave the same dimensions, one can also do C\u003cplot($a-E\u003cgt\u003ecat($b))\u003e, taking advantage\nof PDL threading.\n\n=head2 Interactivity\n\nThe graphical backends of Gnuplot are interactive, allowing the user to pan,\nzoom, rotate and measure the data in the plot window. See the Gnuplot\ndocumentation for details about how to do this. Some terminals (such as wxt) are\npersistently interactive, and the rest of this section does not apply to\nthem. Other terminals (such as x11) have the downside described here.\n\nWhen using an affected terminal, interactivity is only possible if the gnuplot\nprocess is running. As long as the perl program calling PDL::Graphics::Gnuplot\nis running, the plots are interactive, but once it exits, the child gnuplot\nprocess will exit also. This will keep the plot windows up, but the\ninteractivity will be lost. So if the perl program makes a plot and exits, the\nplot will NOT be interactive.\n\nDue to particulars of the current implementation of PDL::Graphics::Gnuplot, each\ntime C\u003cplot()\u003e is called, a new gnuplot process is launched, killing the\nprevious one. This results only in the latest plot being interactive. The way to\nresolve this is to use the object-oriented interface to PDL::Graphics::Gnuplot\n(see L\u003c/\"CONSTRUCTORS\"\u003e below).\n\n\n=head1 OPTIONS\n\n=head2 Plot options\n\nThe plot options are a hash, passed as the initial arguments to the global\nC\u003cplot()\u003e subroutine or as the only arguments to the PDL::Graphics::Gnuplot\ncontructor. The supported keys of this hash are as follows:\n\n=over 2\n\n=item title\n\nSpecifies the title of the plot\n\n=item 3d\n\nIf true, a 3D plot is constructed. This changes the default tuple size from 2 to\n3\n\n=item nogrid\n\nBy default a grid is drawn on the plot. If this option is true, this is turned off\n\n=item globalwith\n\nIf no valid 'with' curve option is given, use this as a default\n\n=item square, square_xy\n\nIf true, these request a square aspect ratio. For 3D plots, square_xy plots with\na square aspect ratio in x and y, but scales z. Using either of these in 3D\nrequires Gnuplot \u003e= 4.4\n\n=item xmin, xmax, ymin, ymax, zmin, zmax, y2min, y2max, cbmin, cbmax\n\nIf given, these set the extents of the plot window for the requested axes. The\ny2 axis is the secondary y-axis that is enabled by the 'y2' curve option. The\n'cb' axis represents the color axis, used when color-coded plots are being\ngenerated\n\n=item xlabel, ylabel, zlabel, y2label\n\nThese specify axis labels\n\n=item hardcopy\n\nInstead of drawing a plot on screen, plot into a file instead. The output\nfilename is the value associated with this key. The output format is inferred\nfrom the filename. Currently only eps, ps, pdf, png are supported with some\ndefault sets of options. This option is simply a shorthand for the C\u003cterminal\u003e\nand C\u003coutput\u003e options. If the defaults provided by the C\u003chardcopy\u003e option are\ninsufficient, use C\u003cterminal\u003e and C\u003coutput\u003e manually.\n\n=item terminal\n\nSets the gnuplot terminal (with the gnuplot C\u003cset terminal\u003e command). This\ndetermines what kind of output Gnuplot generates. See the Gnuplot docs for all\nthe details.\n\n=item output\n\nSets the plot output file (with the gnuplot C\u003cset output\u003e command). You\ngenerally only need to set this if you're generating a hardcopy, such as a PDF.\n\n=item extracmds\n\nArbitrary extra commands to pass to gnuplot before the plots are created. These\nare passed directly to gnuplot, without any validation. The value is either a\nstring of an arrayref of different commands\n\n=item dump\n\nUsed for debugging. If true, writes out the gnuplot commands to STDOUT\nI\u003cinstead\u003e of writing to a gnuplot process. Useful to see what commands would be\nsent to gnuplot. This is a dry run. Note that this dump will contain binary\ndata, if the binary plotting is enabled (see below)\n\n=item log\n\nUsed for debugging. If true, writes out the gnuplot commands to STDERR I\u003cin\naddition\u003e to writing to a gnuplot process. This is I\u003cnot\u003e a dry run: data is\nsent to gnuplot I\u003cand\u003e to the log. Useful for debugging I/O issues. Note that\nthis log will contain binary data, if binary plotting is enabled (see below)\n\n=item binary\n\nIf set, binary data is passed to gnuplot instead of ASCII data. Binary is much\nmore efficient (and thus faster). Binary input works for most plots, but not for\nall of them. An example where binary plotting doesn't work is 'with labels'. The\nefficiency gains are well worth it most of the time, so binary is the default.\nSet C\u003cbinary =E\u003cgt\u003e 0\u003e to go back to ASCII.\n\n=back\n\n\n=head2 Curve options\n\nThe curve options describe details of specific curves. They are in a hash, whose\nkeys are as follows:\n\n=over 2\n\n=item legend\n\nSpecifies the legend label for this curve\n\n=item with\n\nSpecifies the style for this curve. The value is passed to gnuplot using its\n'with' keyword, so valid values are whatever gnuplot supports. Read the gnuplot\ndocumentation for the 'with' keyword for more information\n\n=item y2\n\nIf true, requests that this curve be plotted on the y2 axis instead of the main y axis\n\n=item tuplesize\n\nSpecifies how many values represent each data point. For 2D plots this defaults\nto 2; for 3D plots this defaults to 3.\n\n=back\n\n=head1 FUNCTIONS\n\n=head2 plot\n\n=for ref\n\nThe main plotting routine in PDL::Graphics::Gnuplot.\n\nEach C\u003cplot()\u003e call creates a new plot in a new window.\n\n=for usage\n\n plot(plot_options,\n      curve_options, data, data, ... ,\n      curve_options, data, data, ... );\n\nMost of the arguments are optional.\n\n=for example\n\n use PDL::Graphics::Gnuplot qw(plot);\n my $x = sequence(101) - 50;\n plot($x**2);\n\nSee main POD for PDL::Graphics::Gnuplot for details.\n\n\n=head2 plot3d\n\n=for ref\n\nGenerates 3D plots.

One advantage of making plots this way is that\nthere's a gnuplot process associated with each PDL::Graphics::Gnuplot instance,\nso as long as C\u003c$plot\u003e exists, the plot will be interactive. Also, calling\nC\u003c$plot-E\u003cgt\u003eplot()\u003e multiple times reuses the plot window instead of creating a\nnew one.\n\n\n\n=head1 RECIPES\n\nMost of these come directly from Gnuplot commands. See the Gnuplot docs for\ndetails.\n\n=head2 2D plotting\n\nIf we're plotting a piddle $y of y-values to be plotted sequentially (implicit\ndomain), all you need is\n\n  plot($y);\n\nIf we also have a corresponding $x domain, we can plot $y vs. $x with\n\n  plot($x, $y);\n\n=head3 Simple style control\n\nTo change line thickness:\n\n  plot(with =\u003e 'lines linewidth 4', $x, $y);\n\nTo change point size and point type:\n\n  plot(with =\u003e 'points pointtype 4 pointsize 8', $x, $y);\n\n=head3 Errorbars\n\nTo plot errorbars that show $y +- 1, plotted with an implicit domain\n\n  plot(with =\u003e 'yerrorbars', tuplesize =\u003e 3,\n       $y, $y-\u003eones);\n\nSame with an explicit $x domain:\n\n  plot(with =\u003e 'yerrorbars', tuplesize =\u003e 3,\n       $x, $y, $y-\u003eones);\n\nSymmetric errorbars on both x and y. $x +- 1, $y +- 2:\n\n  plot(with =\u003e 'xyerrorbars', tuplesize =\u003e 4,\n       $x, $y, $x-\u003eones, 2*$y-\u003eones);\n\nTo plot asymmetric errorbars that show the range $y-1 to $y+2 (note that here\nyou must specify the actual errorbar-end positions, NOT just their deviations\nfrom the center; this is how Gnuplot does it)\n\n  plot(with =\u003e 'yerrorbars', tuplesize =\u003e 4,\n       $y, $y - $y-\u003eones, $y + 2*$y-\u003eones);\n\n=head3 More multi-value styles\n\nPlotting with variable-size circles (size given in plot units, requires Gnuplot \u003e= 4.4)\n\n  plot(with =\u003e 'circles', tuplesize =\u003e 3,\n       $x, $y, $radii);\n\nPlotting with an variably-sized arbitrary point type (size given in multiples of\nthe \"default\" point size)\n\n  plot(with =\u003e 'points pointtype 7 pointsize variable', tuplesize =\u003e 3,\n       $x, $y, $sizes);\n\nColor-coded points\n\n  plot(with =\u003e 'points palette', tuplesize =\u003e 3,\n       $x, $y, $colors);\n\nVariable-size AND color-coded circles. A Gnuplot (4.4.0) quirk makes it\nnecessary to specify the color range here\n\n  plot(cbmin =\u003e $mincolor, cbmax =\u003e $maxcolor,\n       with =\u003e 'circles palette', tuplesize =\u003e 4,\n       $x, $y, $radii, $colors);\n\n=head2 3D plotting\n\nGeneral style control works identically for 3D plots as in 2D plots.\n\nTo plot a set of 3d points, with a square aspect ratio (squareness requires\nGnuplot \u003e= 4.4):\n\n  plot3d(square =\u003e 1, $x, $y, $z);\n\nIf $xy is a 2D piddle, we can plot it as a height map on an implicit domain\n\n  plot3d($xy);\n\nComplicated 3D plot with fancy styling:\n\n  my $pi    = 3.14159;\n  my $theta = zeros(200)-\u003exlinvals(0, 6*$pi);\n  my $z     = zeros(200)-\u003exlinvals(0, 5);\n\n  plot3d(title =\u003e 'double helix',\n\n         { with =\u003e 'points pointsize variable pointtype 7 palette', tuplesize =\u003e 5,\n           legend =\u003e 'spiral 1' },\n         { legend =\u003e 'spiral 2' },\n\n         # 2 sets of x, 2 sets of y, single z\n         PDL::cat( cos($theta), -cos($theta)),\n         PDL::cat( sin($theta), -sin($theta)),\n         $z,\n\n         # pointsize, color\n         0.5 + abs(cos($theta)), sin(2*$theta) );\n\n3D plots can be plotted as a heat map:\n\n  plot3d( extracmds =\u003e 'set view map',\n          with =\u003e 'image',\n          $xy );\n\n=head2 Hardcopies\n\nTo send any plot to a file, instead of to the screen, one can simply do\n\n  plot(hardcopy =\u003e 'output.pdf',\n       $x, $y);\n\nThe C\u003chardcopy\u003e option is a shorthand for the C\u003cterminal\u003e and C\u003coutput\u003e\noptions. If more control is desired, the latter can be used. For example to\ngenerate a PDF of a particular size with a particular font size for the text,\none can do\n\n  plot(terminal =\u003e 'pdfcairo solid color font \",10\" size 11in,8.5in',\n       output   =\u003e 'output.pdf',\n       $x, $y);\n\nThis command is equivalent to the C\u003chardcopy\u003e shorthand used previously, but the\nfonts and sizes can be changed.\n\n\n\n=head1 COMPATIBILITY\n\nEverything should work on all platforms that support Gnuplot and Perl. Various\nflavors of GNU/Linux have been tested to work. Windows is known to not work at\nthis time, but patches to change this are welcome.\n\n=head1 REPOSITORY\n\nL\u003chttps://github.com/dkogan/PDL-Graphics-Gnuplot\u003e\n\n=head1 AUTHOR\n\nDima Kogan, C\u003c\u003c \u003cdima@secretsauce.net\u003e \u003e\u003e\n\n=head1 LICENSE AND COPYRIGHT\n\nCopyright 2011, 2012 Dima Kogan.\n\nThis program is free software; you can redistribute it and/or modify it\nunder the terms of either: the GNU General Public License as published\nby the Free Software Foundation; or the Artistic License.\n\nSee http://dev.perl.org/licenses/ for more information.\n\n=cut\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdkogan%2Fpdl-graphics-gnuplot","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdkogan%2Fpdl-graphics-gnuplot","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdkogan%2Fpdl-graphics-gnuplot/lists"}
