Installing the ChartDirector for Python on Ubuntu Linux and Demo to Create 3D Pie Charts

[Eli]

Below are step-by-step instructions for Installing the ChartDirector for Python 3.6.x on Ubuntu Linux. First, download the appropriate version from here (currently this one) and then follow the instructions below:

Code: [Select all] [Expand/Collapse]

1. $tar -xf chartdir_python_linux_64.tar.gz
2. $cd ChartDirector/
3. $ipython3 -c "import sys; print(sys.path)"
4. // Or
5. $ipython3
6. >>import sys
7. >> print(sys)
8. ['/home/elimboto/.local/bin', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '', '/home/elimboto/.local/lib/python3.6/site-packages', '/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages', '/home/elimboto/.local/lib/python3.6/site-packages/IPython/extensions', '/home/elimboto/.ipython']
9.  :~/Desktop/ChartDirector$ cd /usr/local/lib/python3.6/dist-packages
10. $sudo mkdir chartdirector
11. $ cd chartdirector/
12. $pwd
13. /usr/local/lib/python3.6/dist-packages/chartdirector
14. $ cd //Move to the directory where the ChartDirectory is downloaded, in this case  Desktop
15. $:~/Desktop$ cd ChartDirector/lib/
16. $ sudo cp -a ./* /usr/local/lib/python3.6/dist-packages/chartdirector/
17. $ cd /usr/local/lib/python3.6/dist-packages/

And then one can run the following codes.

Below are a number of sample codes (taken from here with some modifications) to create pie charts using ChartDirector 7.0 (Python Edition).

3D Pie Chart

Code: [Select all] [Expand/Collapse]

27.  
28. # Set the pie data and the pie labels
29. c.setData(data, labels)

31. # Draw the pie in 3D with variable 3D depths
32. c.set3D2(depths)
33.  
34. # Set the start angle to 225 degrees may improve layout when the depths of the sector are sorted in
35. # descending order, because it ensures the tallest sector is at the back.
36. c.setStartAngle(225)
37.  
38. # Output the chart
39. c.makeChart("multidepth_pie_chart.png")
