Overlay two graph

[Booz]

Hi everyone!!

I want to create a graphics window with two types of graph inside. One is a candlestick graph, the other is a line graph. I just want to represent the movement of the price with the candlesticks and a moving average with the line graph. I'm finding some difficulties. Someone know how to do it?

I could create a snippet of my code but I don't make any kind of advances in the topic, so I think that is not helpful.

All the help are welcome.
Booz.
