I am using ArcGIS Desktop 10.3.

I often have a problem where my leader lines are overlapping other leader lines in the same layer. I do not want to convert to graphics. I understand how to stop labels overlapping other features, it is the leader lines that are the problem. I use Maplex a lot and have altered all the settings I can think of. Sometimes changing the leader tolerance makes a slight improvement but not all the time.

Example below.

enter image description here

Here I have a long offset because some areas are very busy. All the external zones are allowed. These are currently advanced callouts but I'm having the same problem with simple ones.

Is there a setting I'm missing somewhere?

  • Are you using the standard label engine? If so, try the maplex label engine. There are more options for setting rules using maplex. – GBG Mar 30 '17 at 17:03
  • No, I am using Maplex. As stated in the post I have altered a lot of settings with no luck. – Emma White Mar 31 '17 at 8:16

Maplex tries to avoid overlapping leader lines, but it still does happen occasionally. You could convert to annotation and manually move the problem labels, but as you stated, you don't want to do that.

Are you using the maximum offset option? You may get better results with a smaller initial offset (say 5 points), but a large maximum (say 1000%). This will give you labels with an offset between 5 and 50 points, but will greatly increase labeling time, however.

  • Thank you, I shall make a note of this as I am not currently in a position to recreate the problem. I appreciate your response and will report back when I can. – Emma White Jun 22 '17 at 8:31
  • This worked, thank you. Still a bit hit and miss but way better than what i had before. Inconsistent leader lengths are not ideal but you have to take what you can get. Thanks – Emma White Jul 21 '17 at 7:11
