Heatmap with decimal values not working

[BadDub]

I have a heatmap created that uses decimal values. When I hover over the labels its meant to highlight all the cells that are within that range. But as my values and ranges use decimal values it does not hover the correct cells. It seems like its treating the decimal values as integers. An example is show below.

What can I do to solve this issue?

Resolved it by changing both parseInt to parseFloat in the highlightRangeInSeries function
