I have a map with a Site feature class with two key attributes:  species and year. I have successfully displayed sites using Symbology > Multiple Attributes > Quantity by Category. I used species for the first of the three value fields. I used year for the Symbol Size. This gives me a different color for each species, and a different size for each year.

Unfortunately, on the legend, I get a separate symbol for each combination of species and year. With about 10 species and 5 years, this means I get 50 symbols on the legend. All I want is one symbol showing the color for each species, and one scale that shows year by size.

I think this has got to be a common issue. Any suggestions on how to clean up my 50-item legend?

Thanks!

Rick,

you can always right-click your legend and convert it to graphics. After that right-click it again choose Ungroup. Now you can delete points you don't like and clean up your legend.

Hope this helps!

You could also consider creating "shadow" Feature Classes in the TOC (Table of Contents) of ArcMap with the appropriate legend (symbols). Then create a legend based on these while excluding all the other layers you want to display and make the legend non-dynamic to retain the shadow layers, then deselect the shadow layers in the TOC to make them invisible.

Tim,

Thanks for your suggestion -- worked exactly as you described. And it's a good enough solution, although it doesn't give me quite what I want, because, in the original legend, I get, for example, the species indicator ("CBL"), with a yellow circle with the year ("2009") next to it. After ungrouping, I'd ideally like to have just "CBL" plus the yellow circle, but I don't see a way that I can edit the "2009" out of the legend.

Rick,

before you do what I have suggested, right click your legend and choose properties. Go to the items tab. On the left side, right-click the feature you would like to change the style of and click style. Maybe one of the styles doesn't have the date attached?

Let me know!
