How to set en exact minimum value for spectrum display mode?

[yamac-kurtulus]

Hello, first of all, I believe you have filled some very major gap in grafana with your plug in. Kudos to that.

I am using statusmap in spectrum mode to view some continuous values of services between 0-1. In the spectrum mode, I want to see red for 0, and 1 for green and the gradient for everything in between. When everything is green (1) and some value changes to, say, 0.88, then the spectrum is fitted to 0.88-1 Lowest value becomes red, and the legend shows the colors of 0.88-1.0 range. Is there a way to tell the plugin to assume lowest value to be 0?

Note: I tried setting min and max values of color scale in color section.

Hello! Thank you for your kind words!

This problem is definitely a bug as stated in #124.

The idea of min value and max value inputs is borrowed from standard heatmap-panel: values from the datasource are clamped to the range of min and max. No additional UI switch is required, the restrict flag from PR#134 should be on if there is something in min and/or max inputs.

I've planned to fix this problem and add tests by the end of the month. However, feel free to rework your PR, it is great to see new contributors!

I thought this was a use case so I wanted to include a switch.

Any way, I have just updated #134. I did not want to merge #132 (solving #124) to this one because it might not be the right way to do it.
