Add mouse-over and click functionality? Handling windows events in indicator?

Wait a minute. If you are using the c# draw methods to draw your object, then you have the graphics object.

How are you drawing the object? code?

I hadn't coded the image yet. I assume something like

graphics.DrawImage(...,...);

in the Plot() would be enough, assuming I figure out where on the filesystem to load the jpg from.

Treat those drawings like any other object. Declare and initialize them, then assign them. That way you know what the object is, and you can handle it as you please. Take a look at the CustomPlotSample.cs file to see how it is done.

But I don't get a reference to them when I call the graphics object, and it doesnt seem that I can declare and initialize anything helpful either for the graphics calls either. At least nothing that CustomPlotSample.cs demonstrates.

AFAIK now I need a control or a sub-class of a control, because that is the only thing I can use to attach events to, but I dont have anything except the ChartControl.

(The same theory applies to creating tooltips which you suggested earlier, it seems)

Correct me if I'm wrong, please, but I'm sitting on lame duck here.

In case there is an obvious solution that I am missing, could you state it in terms of

graphics.FillEllipse(brush, rectangle);

rather than graphics.DrawImage() which I have abandoned to avoid requiring a file.

[EDIT] Now that I'm thinking a bit more clearly thanks to some well-timed caffeine, I figured it would be simple to place a control on the chart instead of drawing an image or a circle, and then I won't have any problem attaching the tooltip / label pop-up.

The question is, would a tiny button be OK in case I have to show 100 of these things on the chart in one plot?

(Is this still sane? It comes from about 4 hours of googling)
