# BQN-Gnuplot

A BQN wrapper script for Gnuplot on linux. Tested on CBQN.

Usage:

------

Import:

```

⟨Gnuplot⟩ ← •Import "Gnuplot.bqn"

```

Create a plot window:

```

plt ← Gnuplot @

```

When creating a plot you can include 'set' options as either a list of strings or a single string:

```

plt ← Gnuplot ⟨

  "title 'Title'" # use '' instead of "" when needed

  .

  .

  .

⟩

plt ← Gnuplot "

  terminal pngcairo

  output 'output.png'

  .

  .

  .

"

```

Additional plot options can be given with `.Set` and `.Unset`:

```

plt.Set "

  xlabel 'x'

  ylabel 'f(x)'

"

plt.Unset "

  key

"

```

Data is expect as a flat, rank 1 or 2 array, with major cells corresponding to lines in gnuplot's data format:

```

data1 ← >⟨  # points in major cells

  0‿5

  1‿6

  2‿7

  3‿8

⟩  

data2 ← 8‿7‿6‿5

data3 ← >⟨

  1‿2‿3‿4

  1‿3‿5‿7

  1‿4‿7‿10

  1‿5‿9‿13

⟩

```

Use `.Plot` (or `.SPlot` for 3d plot types) to plot the data, giving options as a joined string:

```

plt.Plot data1‿"with lines"

plt.Plot data2             

plt.SPlot data3‿"matrix with lines"

```

Data can also contain strings for uses such as labeling bar charts:

```

stringdata ← >⟨

    "label A"‿3

    "label B"‿7

    "label C"‿5

⟩

plt.Set ⟨"boxwidth 0.5","style fill solid"⟩

plt.Plot stringdata‿"using 2:xtic(1) with boxes"

```

Additionally, functions in strings can be passed to gnuplot to evaluate:

```

plt.Plot "sin(x)"‿"with impulse"

```

Finally, to show the plot:

```

plt.Show @

```

To use Gnuplot's Multiplot features make sure multiplot is set when creating the window:

```

mplt ← Gnuplot "

  multiplot layout 2,1 title 'Multiple plots' font ',20'

"

```

Plot the contents of the first subplot:

```

mplt.Set "title 'Subplot 1'"

mplt.Plot "x**2/10"

mplt.Plot "cos(x)"‿"with points"

```

Then use .Subplot to begin the next plot, after which you can set and unset options specific to that plot.

```

mplt.Subplot "title 'Sub-plot 2'"

mplt.Set "title 'Subplot 2'"

mplt.Unset "key"

mplt.SPlot "x*y"

```
