Change color theme in plot legend of FIt Curve
I am doing a fit curve and would like to alter the color theme of the plot of grouped lines. I can't find syntax to be able to do this. I found some links to XPath work for doing something similar in graph builder ( {legend box ref }<< Categorical Color theme() ) but that doesn't seem to work in the fit curve report. Grabbing the XML, it wasn't clear if needing a different node was my issue...
