Colors don't render in history.html when min/max values are equal

Hi there,

What is your reason for this feature request?
If implemented it means a value of 10.0 would be shown as #1933E1, but 9.9 or 10.1 will not be assigned a colour.

First, let me state that I am new to weewx and trying to figure things out.

I am trying to heat map various historical data. But now that I see your response it makes sense now. I was thinking if minvalues = 0, 10 had a temp of 9.9 it would show #0000ff". But if the min and max values are equal, I can see where they would not display any colors.

Thanks for your skin and work on this.
