Graph

The Graph widget is a widget for displaying plots. It supports drawing multiple plot with different colors on the Graph. It also supports a title, ticks, labeled ticks, grids and a log or linear representation on both the x and y axis, independently.

Screenshot

To display a plot. First create a graph which will function as a "canvas" for the plots. Then create plot objects e.g. MeshLinePlot and add them to the graph.

To create a graph with x-axis between 0-100, y-axis between -1 to 1, x and y labels of and X and Y, respectively, x major and minor ticks every 25, 5 units, respectively, y major ticks every 1 units, full x and y grids and with a red line plot containing a sin wave on this range::

from math import sin
from kivy.garden.graph import Graph, MeshLinePlot
graph = Graph(xlabel='X', ylabel='Y', x_ticks_minor=5,
x_ticks_major=25, y_ticks_major=1,
y_grid_label=True, x_grid_label=True, padding=5,
x_grid=True, y_grid=True, xmin=-0, xmax=100, ymin=-1, ymax=1)
plot = MeshLinePlot(color=[1, 0, 0, 1])
plot.points = [(x, sin(x / 10.)) for x in range(0, 101)]
graph.add_plot(plot)

The MeshLinePlot plot is a particular plot which draws a set of points using a mesh object. The points are given as a list of tuples, with each tuple being a (x, y) coordinate in the graph's units.

You can create different types of plots other than MeshLinePlot by inheriting from the Plot class and implementing the required functions. The Graph object provides a "canvas" to which a Plot's instructions are added. The plot object is responsible for updating these instructions to show within the bounding box of the graph the proper plot. The Graph notifies the Plot when it needs to be redrawn due to changes. See the MeshLinePlot class for how it is done.

Install

pip install kivy_garden.graph

CI

Every push or pull request run the GitHub Action CI. It tests the code on various OS and also generates wheels that can be released on PyPI upon a tag. Docs are also generated and uploaded to the repo as well as artifacts of the CI.

How to release

  • update __version__ in kivy-garden/graph/__init__.py to the latest version.
  • update CHANGELOG.md and commit the changes
  • call git tag -a x.y.z -m "Tagging version x.y.z"
  • call python setup.py bdist_wheel --universal and python setup.py sdist, which generates the wheel and sdist in the dist/* directory
  • Make sure the dist directory contains the files to be uploaded to pypi and call twine check dist/*
  • then call twine upload dist/* to upload to pypi.
  • call git push origin master --tags to push the latest changes and the tags to github.
