Add more colours to heat grid chart
I have a Heat Grid chart and I would like it to offer more than just three colours.
My heat grid is based on consumption data so it would be great if it could go through a number of colours as the consumption gets higher. As the current three colours include the negative of the max, it currently only means that the middle and max colours are actually used in my data set (I have no negative numbers).
Would it be possible to either make the min colour based on the min value from the data set and not the negative of the max? or is it possible to use more colours in this chart?
