Heatmap with x/y/temperature

Jul 22, 2013 at 6:17 PM
How can I plot the X/Y coordinates and create a heatmap of the temperature at that point using the HeatMapSeries? I see the examples all use x/y only.

Can anyone assist on this, please? I'm looking at the LibrarySamples for HeatMapSeries, but I can't determine what to supply to the data.

I have a set of vertexes (elements) as such: example: first row is a triangle, so I have to connect from point 1 to point 2, to point 29, by looking up the X/Y in the points points table below this one.
1 2 29 29
2 3 30 30
2 30 29 29
3 4 30 30
4 5 31 31
4 31 30 30
5 6 32 32
5 32 31 31
6 7 33 33
6 33 32 32
7 8 33 33
8 9 34 34
8 34 33 33
9 10 53 53
9 53 34 34
etc...
and a related set of points, x/y/temperature values as such: col 1 = X, col 2 = Y, col 3 = temperature value

In my app, I draw a mesh by iterating through the elements, and for each I find the associated line in the points table. Example. 1, 2, 29, 29 in the elements table means to get the X/Y coordinates from line 1, line 2, line 29. I'm supplyng these points to the OxyPlot series.

I've done the meshing successfully, but now I need to create a heatmap of the temperatrues at the given points. As mentioned above, I don't know what to supply the the "data" for the HeatMapSeries.

Can anyone help?

Note: the tables above are a very small subset of the full table.


Thanks
