Autoscale with Plot Override

[photog53]

I have code that uses a plot override...

"public override void Plot(Graphics graphics, Rectangle bounds, double min, double max) "
-----------------------------------------------------------------------------------------------------------------------

The code works as intended...plotting a small line at the left edge of the chart, towards the
top. (created by a graphics path and then plotted it using graphics.DrawPath( etc. etc.)

My problem is that occasionally, when price drops, this plot will 'scale' off' the chart
temporarily disappearing from view. If I manually compress the chart by dragging on the right side, the line shows up, so I know the plot did not disappear...it only scaled off the visible chart..


I have AutoScale = true.....
but for whatever reason this line doesn't seem to 'hold' the scale.


What am I missing?
Why does AutoScale not seem to work for this plotted line?

Thanks..........

photog53, the AutoScale would only apply to regular drawing / plot objects, not to the custom ones generated via the C# Plot override. You can look into adding a regular transparent plot or drawing object at your min / max values so the AutoScale would factor those in.

Thanks.....

I was afraid that would be the case....but frequently you guys have very elegant solutions that I had not thought of, so I generally ask the question.
