Listers, Anyone working with geology maps will understand the necessity of having the geologic units placed in the correct stratigraphic order in the legend. MI will not do this for you automatically, but there's a fairly simple workaround. Many thanks to all who responded with various ideas, and especially to Mal Jones who forwarded a very complete set of instructions he's created in Word. Rather than post an attachment to the list, I'll just suggest you contact Mal directly to see if he's willing to pass on a copy: [EMAIL PROTECTED] Anyway, here's the simplest solution: 1. Add a new Integer field called Order to your table of geologic units. 2. Assign each geologic unit a number, starting with 0 or 1 for the youngest unit. 3. From Map>Create Legend: Select the table in the Legend Frame; can usually accept the defaults in the next window; in Step 3, edit the title, select Styles from: Unique values in column, and specify column name “Order”. 4. Label the legend objects as desired - Mal's instructions had some good ideas for this. MI will now order the legend items in the correct stratigraphic (or chronological) order. There were some other suggestions about editing the workspace, but this seemed more complicated and potentially dangerous. Editing workspace files should NEVER be attempted without first making a copy of the workspace file, particularly if you've invested a lot of time on a complicated layout. As for my second question about how to get the MI to display a proper scaled-circle legend, the short answer is it can't. The main problem is that MI's scaled-symbol thematic mapping function provides only a crude approximation of true scaled-symbol mapping. This is because MI scales the symbols using font sizes, which are only available in a limited range of rather large steps, rather than a continuous range of symbol sizes. My workaround for this was to write an MB app that puts properly-scaled buffers around the data points. Cheers, Tim _____________________________ Tim Warman Geologist & GIS Specialist Richard C.
