Trippy gradient when drawing a heatmap based on very few values #6

Description

@rikkertje-dap

Hello!

I'm contributing to an application that draws heatmaps based on some plotted values in a schematic representation of a greenhouse.

The problem I'm running into, however, is that when you have very small amount of values (as represented by the white circles with numbers) the heatmap becomes a little bit trippy and not very reliable.

It seems that every step between the 5 and 50 is shown by means of a gradient. It's quite logical, but not the effect I hoped to achieve. Besides, as you can see, the direction the gradient is taking is also not very logical or balanced. Therefore the heatmap becomes less reliable.

I hope you get what I'm saying!

Do you know anything I can do about it to make the heatmap more balanced and more smooth?

Thanks!
