随时提供基本图表-Golang开发

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.
