Sorry Beni you'll get this twice as I forgot to send to the list... The function def p_continuation (I know not the one you're using). has the line: if known(ATTR__text) and picture(ATTR__text): This seems to work, but not sure if it's because of the next few lines: % set labeling color to light orange push_label_fill_color(0.8, 0.8, 0.0);​ % draw filled label with text next to symbol ?​ p_label.urt(ATTR__text,(.5u,-.25u) transformed T,0.0,8);​ % restore original labeling color​ pop_label_fill_color;​ fi; It seems like the P_label.urt is fairly important, as this is what tells it where to place the label, in this case in the upper right (.urt) and then tells it to put the attr_text there.

Hi there, i need some new point symbol (text label). Its a simple text on white color within a box with rounded corners, like the attached image.

My metapostskills are not good enough to get this to work...

For now i would be happy to have such a user point symbol. It would be important that it scales well and react to xtherions direction setting.

Optional it would be cool if the default symbol could show the current survey identifier of the nearest station in the scrap and maybe also the nearest next survey. But this information could also be maintained manually for now.

Is there someone here for my rescue? :) Thanks in advance, Beni
