QUESTION
I am just starting out to experiment with visualization in Python. With the following code, I am trying to add sort functionality to a Matplotlib bar plot which is drawn from a data frame. I would like to add a button
on the graph like sort
, so that when it's click it would display a new plot in the order from the highest sales figure to lowest sales figure, currently the button can be display yet the sort function cannot be triggered. Any idea or pointer would be appreciated.

Answered 2021-Jan-09 at 09:40I have included two reproducible examples using the famous titanic
dataset to a basic comparison of class
vs. # of survivors
for interactive sorting for both matplotlib
bar
and plot
(i.e. line) sorting on the x-axis below:
With bar
plots you have to loop through the rectangles using set_height
, e.g. for r1, r2 in zip(l,y): r1.set_height(r2)
and for line
plots, you use set_ydata
, e.g. l.set_ydata(y)
.
Make sure to use %matplotlib notebook
if using a jupyter notebook.

I'm using a raspberry pi 3 with raspbian jessie and I cross compiled Qt 5.6.4 and PyQt5 to make an embedded device, on my app, everything works well, it use the EGLFS driver so there's no X server running (I deactivated it), however, on my app, I have a button that open a matplotlib plot, which is configure to show as fullscreen, and it worked well on the X server (the first test I ran), however, now that I'm using eglfs without x server, the plot appears just in the top left corner of the screen, I will post a picture and my graph code.
And my code:

Answered 2018-Jul-27 at 05:59I'm going to answer my own question, seems like Embedded Qt have problems with the pyplot module, so when I execute the matplotlib script it just doesn't adjust properly to the screen because there is no X server, I tested it and with X server everything works just fine.
Now, if you don't want to use the X server (as me), you need to use the MatPlotlib python widget for the Qt Designer, so you can create a QWidget or a QMainWindow with a plot figure on it, then, you can create a python script to add everything you need to that plot, and it will be as just another Qt window, but with your plot as desired.
