Stacking markers to create a heatmap

[hsellik]

Hi,

I have two questions.

1. Is it possible to stack up multiple markers on top of each other?

The idea would be that the first marker would be light and the subsequent overlapping markers would make the highlight darker. Kind of creating a heat map. Right now, the markers that get added, override the CSS.

If overriding CSS with the last class is inevitable, I was thinking about getting the ranges and checking the overlap myself, then adding a CSS class which is equivalent to the overlap level.

The problem then becomes, that I need to get 1-d intervals, instead of the 2-d intervals that I currently have. So the second question is.

2. Is there a way to convert betweem the 2-d interval (startRow: number, startColumn: number, endRow: number, endColumn: number) and a 1-d interval (startIndex: number, endIndex: number)?
