I'm a long-time user of SciChart, but it's an old version (3.1). I've just started using FastHeatMapRenderableSeries for the first time, and there is a requirement for a user to alter the chart's gradient stops. I've implemented a UI to do this (see image), which involves dragging markers that updates their respective gradient stop within the ColorMap's LinearGradientBrush. It's working in as much as gradient changes can be seen in the chart's HeatColorMap (not shown on this screenshot), and also in my "drag" control (a Rectangle whose Fill is bound to the ColorMap's brush).
The problem is that the colours within the chart itself don't change - perhaps I was being a little too hopeful that this would happen automatically! Is this possible, or will I have to recreate the series each time there has been a change to the gradient?
