Two indicators in one window- how to

I am trying to add two indicators in one window
like a stoc and a moving average on it.
I have selected it and dragged to the window but that does not work

So if you want to make a moving average of a Stoch,

Place the Stoch on the chart.

then select the moving average you want and drag that onto the Stoch.

then select in the apply to window. Apply to previous indicator...

That should do it
