Adding charting options

I have a chart layout that displays candlesticks. I want the ability to be able to switch to OHLC bars and back again, but this option doesn't appear in the Parameters window. How do I get to the code to add that option in?

Replace styleCandle by GetPriceStyle() in your price plot.

Plot( C, "Price", colorDefault, GetPriceStyle() );

Then go to View / Price chart style and change to other price styles there.
