Modify color gradient on Elastic Maps

Hi,

I've working with maps for a few months now and I'm wondering if there's any way to modify the color gradient range and adjust the maximum value for the maps.

For example, in a range from 1 to 100, if the max value in my index is 23 I don’t want that document to have the darkest possible color instead it should have a color closer to the minimum or lightest color.

Is there any way to do this in Kibana 7.3 ?

Thank you!

Custom color ramps where introduced in 7.4 so I'm afraid you'll need to update.
