cxGeoPlotGetLastError - returns last error associated with the current plot

The source of the LineGraph module may be found in $EXPLORERHOME/src/LineGraph/linegraph.c on UNIX machines, and %EXPLORERHOME%\src\LineGraph\linegraph.c on Windows machines. It illustrates the use of many of the cxGeoPlot* routines.
