I'm almost done with a humongous project except I'm just stalled on one certain point.
I want to cut and paste the screenshots of my work, but I can't do it on here. Can someone help me out via email?
I just have one problem, and I've gotten so far on my own.
My email's email@example.com
Solved! Go to Solution.
Orrin, I told you how to do what your asking: "right click the layer in the table of contents, select copy, past it in to your table of contents, and then change the symbology of the copied layer as described in the help file." I don't really know how else to describe it to you. Yes, you can have multiple attributes of one layer displayed by copying and pasting the layer again into the table of content and having different symbology for each copy. Of course you can have county names as well as percentages. The software is actually incredible versatile and powerful if you know how to use it.
OK, so here's a category that I want to insert: The percent difference in population change for counties in Oklahoma
I did this by merging a census-downloaded spreadsheet of county change to excel and merging it with a shape tiger file of oklahoma counties:
So, I'm trying to do symbology, so I can shade the counties in Oklahoma based on % population differential, but here's where I run into problems. The field perdiff20102014 appears in the value field here....
But when I get to color ramp to do different classes....this happens:
ALAND and AWATER are the only two options for the color ramp. Those are two variables from the original dataset and not the one I joined it with.
As Dan astutely points out, the values are left aligned indicating that the data is text and not numeric. This has most likely happened when it was imported from Excel. You can quickly check the field type by right-clicking on the field header in the attribute table and selecting ‘Properties’.
If all of the values in the field are numeric you can easily convert them back to numbers:
1. Add a new field to your data:
2. Calculate the field values from your text field:
This should bring all of your values across into the new field and you should notice that the values are right-aligned numbers.
3. Now try to apply your symbology again and the new numeric field should appear as a value option.
Thanks I'm getting closer. The problem is that while I now have numerical values and can adjust the color scheme with classes, when I go back to the main menu, it doesn't let me do that.
Apparently, it did the graduation anyway, but the graduation should be green if it's negative and red if it's positive, so a negative vs positive change can be discerned. Also a minor detail, but a state like Oklahoma should be on landscape view.
It doesn't let me flip unfortunately:
If the fiscal budget data is in another layer, simply change the symbology of that layer as described in this help file: ArcGIS Desktop . If it's in the same layer, then right click the layer in the table of contents, select copy, past it in to your table of contents, and then change the symbology of the copied layer as described in the help file.
How come you are symbolizing by multiple attributes? Don't you just want to do it by quantities and then pick your percent difference field as the value? You should be able to pick any color ramp you want by clicking the arrow by the color ramp and choosing a ramp in the drop down.
