I am wondering if it is possible to control the scale of the colors displayed when an attribute is dragged onto a map. It seems like there can be 5 bins only, and what values go into each of those color bins depends on the spread of the data. I am hoping to get more granularity, and also to be able to keep the color scale the same between data displayed for different years, which have different variability. I can get the min and max to be the same by adding a row with the same min value and one with the same max value to each attribute column, but the values that are grouped into each color scale bin seem to change depending on the data. Is it possible to have more control over this scale? When I click on the ruler icon on the map, it doesn’t provide any options.
The short answer is that CODAP does not provide any way to adjust the numeric legend color scale. As far as I know you are the first person to express a desire for this. Four years ago when we implemented the feature we thought users might want to adjust things but decided to wait and see. Now I’ll certainly add your feature request to our list.
Perhaps you could say a bit about the context in which you are using CODAP and how it would help you to make these adjustments?
I too would like to be able to do this. Look at the following CODAP document I prepared, for example. The banding seems really weird. Like there is one for 21 to 26 cases and another for 140 to 1566 cases. It may have been better to do this as a rate per 100,000 population or something like rather than total numbers but even then I might want to change the range each color represents.
