Labels of proportional symbols
Is there a way to format labels when using proportional symbols? I'm using ArcGIS 10 and there doesn't seem to be a way to do that; slowly double-clicking the label in the table of contents does not produce any result. (I'm using ratio data for the value; the data does not need to be normalized).
In addition, I can choose to have up to 12 symbols displayed in the legend. Why are only 5 symbols ever shown, at most--even if I choose to display more than 5?
Thank you for the information.
Mapping Center Answer:
There isn't a way of formatting labels in the Table of Contents but, of course, you can alter their appearance when you add a legend to a Layout.
The second problem is most likely a bug and this has now been passed to the developers to look into. However, if you are creating a proportional symbol map our advice is that you shouldn't need more than a few 'visual anchors' in your legend. The attachment shows how you might design a legend for proportional symbols. These can be created by adding a legend to your Layout, Converting to Graphics and then rearranging the individual graphic components as you wish. You can add lines and other components using the Draw tools.
There may also be some ideas in this Mapping Center blog post on Bar Chart Legends that you can use when thinking about Proportional Symbol legends. many of the ideas are transferable.
