It looks like this is on the chart itself. We don't offer any custom drawing objects for the chart. The only way I would think something like this even has a chance of working is if you were to create an Image chart object. In your system, you'd render the heat map as an image and apply that as an image chart object.
I'm looking for some sample code to produce a heatmap-like graphics in RE. Example here: http://www.traderblogs.com/themesasoftwareblog/
I'm not talking about one specific indicator calculation, but just code portion of it to turn any 3d data into a heatmap.
Even some tips, hints, or instructions on how to go about programming it in RE would be much appreciated.
Thanks in advance.
