Hi - I am using vn 7.3.     I have been able to use the color-mapped value display rule for a scatter plot.     However I am not given this option for a custom chart I have which consists of a scatter plot on top of a schedule chart.  The scatter plot has a color category.  I have a slider to filter this chart and each time I change the slider values the category colors change.  It is extremely annoying - do you have an idea of how I can set the category colours so they are consistent?   Thanks, Marie ...
