How to make databars in calc using solid color?

Hi, I’m trying to use cell databars in calc to visualize my values, the problem is, that when I add them using conditional formating, it adds it as gradient starting from chosen color and ending white (see image). How to switch it to solid color databar? Gradients are nice, but tells me nothing about the data.

P.S. Can’t embed image here, you’ll find it at:-

using LO 4.2.4.2 running on kubuntu

(Edit: tried to activate image on non-existent domain -AK)

I find no setting for that in the GUI, and it seems there is actually no API-access to change the behavior …
