Is there a way to delete unwanted legend items from legends created with wgautolegend call? I only want to delete the object from the legend not the graph window. I tried to create a custom legend using wgflexlegend but the line style for line plotting doesn't show up and because i'm using ps_solid and ps_dash. I also tried to delete the objects that i don't want in the legend using wgdeleteobj but it will delete it from the graph window too. If deleting only from the legend is possible please reply. Thanks.

You can't delete individual legend items once the legend is created. The flex legend is the best idea, creating a legend with just the items you want. You should be able to use the flex legend for line legends. It looks like you have been using the wrong symbol constants for the flex legend routine. Use LG_LINE for the line symbol, and LGS_DASH or LGS_SOLID for the line style constants. See all of the LG_XXX and LGS_XXX flex legend constants in the qcwin.h file.
