Feature Request: Color Ramp/Palette support for Rule-Based Renderer #43562

Open Saijin-Naib opened 3 years ago

Saijin-Naib commented 3 years ago

Feature description. I think the ability to use/apply Color Ramps and Palettes to the Rule-Based Renderer would be absolutely amazing, as it would open the door to more stylistic options when using advanced categories or multi-variate values (aligning a bit more with ArcGIS's capability in this regard).

You can use refine class or use a classified renderer with an expression. The issue is often changing all the generated symbols afterward..

Which is why I think this would be a massive UX win for this type of symbology. There are already means to adjust the symbols in this page, but bringing over a few controls/concepts from the Categorized renderer would be amazing.

For one, the color ramp/palette control, as well as the "base symbol" stye control. With both of these, I think the ease of use of this renderer would be improved. Far less individual clicking/over-riding needed to meet a bunch of basic styling workflows in this renderer. image

Even using the categorized renderer it would be nice to be able to use a palette of discrete colours, like the "ramp" in your first screenshot (although I don't know if that is really being used to provide discrete colours or if values are actually being interpolated from it).
