Hello,
I am trying to join 2 kind of graph in one : a heat map and an XY chart.
I need that to see where a value is located on a heat map.
I don't really know what are the best practices for that but for the moment I first build a heat map that I write as a .png image file ("PNG chart and Canvas writer" component) and then I set the background of the XY chart with this PNG.
I have however already a problem:
My heat map data are stored in a file in this way:
X Y val
200 -2 val1
200 -1 val2
...
200 7 val10
201 -2 val11
...
And the Y axis goes from 7 to -2 (bottom to top), but I'd like the contrary and I don't know how to change that.
I'll be glad to know how to fix that and/or if this is a good way to do what I want to do.
