Introduction

PyCha is a very simple Python package for drawing charts using the Cairo library. Its lead developer is Lorenzo Gil Sanchez.

PyCha aims to be:

• Lightweight
• Simple to use
• Nice looking with default values
• Customizable

The following charts are currently supported (see screenshots below):

• horizontal bar charts (pycha.bar.HorizontalBarChart)
• vertical bar charts (pycha.bar.VerticalBarChart)
• pie charts (pycha.pie.PieChart)
• line charts (pycha.line.LineChart)
• scatter charts (pycha.scatter.ScatterChart)

New in version 0.5.0.

• stacked horizontal bar charts (pycha.bar.StackedHorizontalBarChart)
• stacked vertical bar chart (pycha.bar.StackedVerticalBarChart)

Support for stacked bar charts is planned for a future release.

PyCha is distributed under the terms of the GNU Lesser General Public License.

If you require more advanced graphs, you might want to consider matplotlib.

Output Formats

PyCha uses the Cairo library so it should support all Cairo surfaces.
