Plotting in Excel with PyXLL and Matplotlib

Author: Tony Roberts, creator of PyXLL, a Python library that makes it possible to write add-ins for Microsoft Excel in Python. Download a FREE 30 day trial of PyXLL here.


Plotting in Excel with PyXLL and MatplotlibPython has a broad range of tools for data analysis and visualization. While Excel is able to produce various types of plots, sometimes it’s either not quite good enough or it’s just preferable to use matplotlib.

Users already familiar with matplotlib will be aware that when showing a plot as part of a Python script the script stops while a plot is shown and continues once the user has closed it. When doing the same in an IPython console when a plot is shown control returns to the IPython prompt immediately, which is useful for interactive development.

Something that has been asked a couple of times is how to use matplotlib within Excel using PyXLL. As matplotlib is just a Python package like any other it can be imported and used in the same way as from any Python script. The difficulty is that when showing a plot the call to matplotlib blocks and so control isn’t returned to Excel until the user closes the window.

This blog shows how to plot data from Excel using matplotlib and PyXLL so that Excel can continue to be used while a plot window is active, and so that same window can be updated whenever the data in Excel is updated. Continue reading
