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

[ghost]

When setting up colors for history.html in skin.conf, if the min and max values are the same, colors to not render. If you offset the values, colors work.

works

minvalues = -10, 0, 10, 20, 30, 40, 50, 60, 70, 80, 90
maxvalues = 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100

colours =  "#0000ff", "#1933E1", "#3266C8", "#4B99AF", "#64CC96", "#7Dff7D", "#96CC64", "#AF9948", "#C86632", "#E13319", "#FF0000"

does not work

minvalues = 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100
maxvalues = 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100

colours =  "#0000ff", "#1933E1", "#3266C8", "#4B99AF", "#64CC96", "#7Dff7D", "#96CC64", "#AF9948", "#C86632", "#E13319", "#FF0000"

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.
