Handling uniform values in Normalizers

Hi,

I encountered a problem in CodeCite that arises when you are using ColorNormalizer and all values are the same (so you cannot scale anything). Is there a standard way to handle that, or I need implement something myself?

Re: Handling uniform values in Normalizers

Hi Uko

I thought about this before.

What would be a decent handling of such a case?

Choose the color for the lowest value? For the highest? Or compute the average color?

For example: What would the user expect when specifying the color from red (for minimum) to blue (for maximum) and all the values are? All red, all blue, or all violet?

I could not find the "natural" answer to this question.

Something I can imagine is that the API is allowing us to set a neutral color, but I am not sure about this. I am however open for discussing it.

Cheers

Ricky

Re: Handling uniform values in Normalizers

One idea would be specifying neutral color. Other idea would be to be able to specify max or min value by yourself, this way one can avoid unexpected situations. For Example in my case I knew that min value is 0. This means that only max is calculated and if it’s the same as min you use minColor if it’s different it automatically becomes maxColor.
