Hi,
I have a plot (derived from the bode example) that can plot multiple curves. I am trying to put legends on either upper left or upper right corner of the canvas to show the name and color of each curve using QwtPlotMarker. Once I added the legends, I want them to stay exactly at the same location but couldn't make it work. Every time user zoom in/out, the legends position changes (sometime out of display), Or every time user append a new curve, the scale changes and the legend position also change
Is there anyway to make the legends appear at a fixed place on the canvas? Is QwtPlotMarker the right way to use (I want a color line with text next to it to show the name of the curve and the color of the curve)?
Thank so much for all your help.
