Dear all,

I am new to QC and trying to find my way on the platform. 

Currently, I have a simple algo (SMA crossing). I would like to add a custom chart to visually observe the crossings. To that end, I am following the instruction: https://www.quantconnect.com/docs/algorithm-reference/charting. I would like to change color & type of series. Yet, I cannot make it work. Any suggestions?
