Charts for Go
=============
Basic charts in go.
This package focuses more on autoscaling, error bars,
and logarithmic plots than on beautifull or marketing
ready charts.
## Examples
## Chart Types
The following chart types are implemented:
* Strip Charts
* Scatter / Function-Plot Charts
* Histograms
* Bar and Categorical Bar Charts
* Pie/Ring Charts
* Boxplots
## Some Features
* Axis can be linear, logarithmical, categorical or time/date axis.
* Autoscaling with lots of options
* Fine control of tics and labels
## Output / Graphic Formats
Package chart itself provideds the charts/plots itself, the charts/plots
can be output to different graphic drivers. Currently
* txtg: ASCII art charts
* svgg: scalable vector graphics (via github.com/ajstarks/svgo), and
* imgg: Go image.RGBA (via code.google.com/p/draw2d/draw2d/ and code.google.com/p/freetype-go)
are implemented.
For a quick overview save as xbestof.{png,svg,txt} run
```bash
$ example/example -best
```
A fuller overview can be generated by
```bash
$ example/example -All
```
## Quirks
* Style handling (especialy colour) is a bit of a mess .
* Text based charts are cute. But the general graphics would be much easier without.
* Time handling code dates back to pre Go1, it should be reworked.
