I think it should be this (not sure, never programmed in Julia):
IupOpen();
IupPlotOpen(); # init IupPlot library
# create plots
plot = IupPlot()
# dialog
hbox = IupHbox(plot, C_NULL);
IupSetAttribute(hbox, "MARGIN", "4x4");
IupSetAttribute(hbox, "GAP", "10");
dlg = IupDialog(hbox);
IupSetAttributes(dlg, "SIZE=500x240" );
IupSetAttribute(dlg, "TITLE", "IupPlot Example");
InitPlots(); # It must be able to be done independent of dialog Mapping
IupShowXY(dlg, IUP_CENTER, IUP_CENTER);
IupSetAttribute(dlg, "SIZE", C_NULL);
IupMainLoop()
IupClose()
It this showing a dialog with at least a white canvas in the center
surrounded by 4x4 margins?
