Facing difficulty trying to overlay a line plot on top of Color Candles (in the separate window)

 
I made a simple candlestick chart in the separate window (DRAW_COLOR_CANDLES). I wanted to make a moving average in the same window, but when the buffers have very different values it causes the candlestick chart to scaled down so much that you can't see it anymore. Is it not possible to do what I'm trying to do? Is it recommended instead to leave a candlestick chart indicator as it is and overlay a separate indicator in the same window instead?
 
I believe you have to create two separate indicators and load each in a separate window.
 
Right, thanks
