I'm having trouble using the colorbar/colormap functions. I create a test plot, plotting a bar graph from 0,0 to 100,100 and created a color bar. I would like the color bar to correspond to the y values of the graph. Which means, if looking at the xaxis, the graph would be colored in the same order as the colorbar from 0->100 by matching the y-values to the colorbar values.
It seems to be plotting the value 0 corresponding to the colorbar which is purple/black every time which I believe is the z-value. Mainly see colorbar/maps used for contour plots but I would like it to work for a 2D plot.
