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.

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.
