Please forgive the crude explanation but I’m unsure how to describe the issue and as they say, a picture says a thousand words, so what I am trying to achieve is to draw a graph in matplotlib that looks like the below:
whereby the scale of the color range is the same across all bars as the x limits of the x-axis.
Having trouble appending a new row to the first row (the header row) in the table body ().
