I have a form that displays a time vs temperature graph when the user

a plot button. The plot is done in a picturebox using gr.drawline. I
would
like for this plot to be made without the user having to click the plot
button, ie when the form opens.
I have tried putting the call to the plotting subroutine in various
places:
the pbox.paint event, the form load event, and several other form events.
Nothing seems to work - I am not getting an error, just no graph. If I
click
the button, it will still plot.
Any ideas how I might get this to automatically occur when the form opens?
Perform the calculation in the form's 'Load' event handler, store the data
in a data structure and draw the graph in the form's 'Paint' event handler
or overridden 'OnPaint' method.
