A more useful relative heat map

[Guitlle]

I believe it is more important to have a relative heatmap. This means that the maximum value in the visible points should be the hottest and the minimum should be the coolests. This is done by getting the maximum and the minimum and making it get a range and an offset.

Please implement this, it would make the heat maps so much more useful.

Many thanks for your contribution, this is exactly what I was looking for!

There is an issue in '_redraw()' when calculating the min/max values, though:
An alt sequence of eg. [0, 10] would give a min value of '10' because 'if (min == false)' is 'true' in the second iteration ('0 == false' is 'true' in javascript). Perhaps an alternative approach would be to use 'var min=0, max=0; ... min=Math.min(min,value); max=Math.max(max,value))' instead?

Thanks grotheandreas1, I'll fix it

[danzel]

Use a === instead

Hi everyone, it would be very useful to have a relative heat map.
@DuGuille will you be able to finish this ?

[Guitlle]

Hi jbouzekri. it's been a while since I posted this. I'll try to finish it this weekend.

[jbouzekri]

Many thanks !!!!

@DuGuille Any update on the schedule? This would be an extremely nice feature

[Guitlle]

Hi. I've found a much better way of doing this. Made a new branch and a new pull request #58
