trying to build some GUI, I've run into some problems concerning the display of data structures:
I have a graphical representation of an array in my data area, which in turn should be visible graph-on-parent one abstraction level above (and even one more level above). However, most data points appear outside the defined box (though in scale, at least), no matter how I adjust the margins (in fact, their values seem to be ignored altogether).
Plus, moving the canvas box will not update the data drawn. What am I overlooking - or are there some known issues around this?
