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. The best to describe this would
be through the use of a picture:

This image shows how the colorbar should look before (the image on the left)
and after (the image on the right) the adjustment. As the threshold values
of the colrobar are changed, the colormap would be updated 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 (like the way
shown in the picture above) when the slider is adjusted. I was wondering if
anyone has done this before and might have a piece of code they would be
willing to share and might have pointers as to how this can be achieved.
