<br>
If I want to “attach” something to a corner of the plot I can usually do it pretty easily.<br>
<br>
e.g Vector reference label:<br>
vcres@vcRefAnnoZone = 0<br>
vcres@vcRefAnnoJust = "TopRight"<br>
vcres@vcRefAnnoParallelPosF = 0.5<br>
vcres@vcRefAnnoOrthogonalPosF = -0.5<br>
<br>
How do I do this with a label bars?<br>
pmLabelBarZone doesn’t seem to behave in the same manner as above.<br>
Trial and error with pmLabelBarOrthogonalPosF is a hassle and then seems to break occasionally if the plot shape changes.<br>
