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?

else:

self.SMA_values = "Fast: " + str(self.fastValue) + ". Slow: " + str(self.slowValue)
self.Log("SMA_signal - " + self.signal + self.SMA_values )
return Hi Kryz,
To resolve the issue please register the chart object:
self.AddChart(smaPlot)Refer to the attached backtest.Best,
