We're using IDL 7.0 from a C++ application executing .pro files. I'm looking at legacy .pro code that sets up a plot using Window, View, and Model objects. I can see where the view size is getting set via the VIEWPLANE_RECT property. It currently expands the x coords to allow for an extra %15 of the total xrange for the plot on both left and right sides to allow for axis info. We then place the left side axis at the first data point specified in the x range so that it stays visible as the data is zoomed in. This all works fine if that 15% is big enough to show the axis info, otherwise it gets clipped. I tried to get the size of the IDLgrAxis object using the XRANGE property after other elements were added to it (like title text) but before the draw was executed, it showed 0,0. So my question is....is there any way to get the size that the IDLgrAxis object will need to display, before it actually gets displayed?
