For the image D (e.g. section of heatmap), could you take a screenshot of
the that covers the point of a dive where you get the image A (e.g. bar
graph)?  Then crop the heatmap to get the exact data point, and use that as
image C (colour mapping of A, e.g. bar graph)

The comparison between the deep stop vs no deep stop dive profiles should
be updated/replaced.  The correction to how the heatmap is plotted (using
lines rather than large dots), and the adjustments to the colour scale,
mean that it is no longer how the heatmaps would look.  A replacement could
be made from doctoring a real dive, like I did for the current version, or
could be done with the planner using the same gasses, depth and bottom dive
with a Buhlmann (e.g GF60/75) and VPM-B plan (e.g. +2).  For the comparison
to be fair, the GF and conservatism needs to be adjusted so the total dive
time needs to be the same.  I'm not sure when I'll next get a chance to
make a new version.
