I am currently trying to work on a program that will allow the user to display their dataset in the form of a colormap and through the use of sliders, it will also allow the user to adjust the threshold of the colormap and thus update the colormap accordingly.
Now I am mainly using matplotlib and I found that matplotlib does support some widgets, such as a slider. However the area I need help in is devising a piece of code which will update the colorbar and colormap
Matplotlib usually just reflects the underlying data so you need to adjust the data values that control the colours and matplotlib will change the display (you may need to force a refresh).
I've not done exactly what you are asking but I have done conceptually similar things with network maps where nodes change color depending on the numbers of alarms they have generated (usually, red, amber, green).
