I have a chart that shows actual data and forecast data on top of each other (see attached). However, I would like to be able to change the color of the curve based on the "Actual/ forecast" status of the data. For example, for each curve, part of it will be actuals (let's color it in red) and the rest will be forecasts (let's color it in green). I don't have this column on my chart though. Is there a way to make it happen?
