When adding a design file to InterPlot Organizer the default origin is "Center" rather than 0,0
Set IPLOT_AUTO_MAXIMIZECENTER_ON_CREATE = false in iplot.cfg.
When this variable is set to TRUE, IPLOT will maximize and center the plot area when an IPARM is first created. When set to FALSE, the plot area is not maximized and centered. The plot size is only maximized if there is no size or scale qualifier specified on the command line or in a settings file. The plot is centered only if there is no origin specified on the command line or in a settings file. The default value is TRUE.
