Michael,
Thanx for the sample code. It looks like it does many of the types
of things I want to do. What I am really trying to do is duplicate
my Stockcharts list in AmiBroker. The problem with Stockcharts is
that I must do everything manually and the lines tend to move over
time. If I could dynamically create the lines each time I pull up
the chart with exact start/end points then the scaling and line
position would take care of themselves through the replot.

In simple design code, it looks like I need to:
-Setup/initialize
-Grab two data sets (OHLC/Date) based on the mouse pointer - I don't
know how to do this yet
-Do my mystical calculations
-Do a number of HLINE/Plot calls such as:
Hline = LineArray(x0,y0,x1,y1,0);
Plot(HLine ,"CycleLine",colorYellow,styleLine);
Once I get it drawing the lines, I will worry about saving and
retrieving the state data necessary to bring back saved charts.
If you have any more suggestions or code samples you think may help
I appreciate your help.
Thanx.
Andy
