There does not appear to be a legendLineColor property – when I change the lineColor for the data series, the legend continues to show the line in blue. The markerColor and markerBorderColor are correctly used in the legend but not the line color.
SOLVED: Setting the “color” property seems to control the legend as well as the data series. Setting the legend and marker colors alone wasn’t sufficient.
Glad you figured it out. Also, you can set the legend marker color using the legendMarkerColor property. Please take a look at this documentation page for more information.
