MultiCharts: Trading Software for Automated Trading and Backtesting

Can anyone show me how to plot a dot above or below a bar? I want to plot a dot above the bar when h>h[1] and plot a dot below the bar when l<l[1] and be able to see them historically too.
Thank you.

First, you need to decide the "Offset" -- the distance between the H and the dot.

ps. This is a start; I have not verified the code.

Thanks TJ. So the type of Plot is always set later in the Properties. And this will work on historical bars also?
Thanks.

The setting is applied to the chart as it is drawn on the screen.
