Horizontal legend for raster files
It would be nice if ArcGIS Pro or ArcMap allow you to create and customize a horizontal legend for raster files.
Example:
I have a polygon layer that I have symbolized with an unclassed light to dark blue color scheme. When I add a legend, it shows a vertical bar. Currently there is no option for rotating just the color bar 90 degrees.
This is the default legend:
This is similar to the result I want:
A workaround is to rotate the legend 90 degrees, adjust the patch size (and spacing if using classes in your symbology), and then add separate text boxes for the labels. A bit cumbersome when it comes to sizing the color bar. For example - to be centered perfectly below the map requires a bit of trial and error trying different patch widths to find a good fit.
Legend rotated 90 degrees:
Increased patch width to 200 pt:
From here you can disable all the legend labels and add separate text boxes.
There are other options such as developing everything in an image editor (Photoshop, Inkscape) and bringing the legend back in as a graphic, but would be nice to have that function right in Pro.
Love this idea! I cobble something together in PowerPoint (gotta work with what you've got 🤕😂) like this & add it to dashboards as an image sometimes:
Depending on the dashboard, this layout can be easier to read and a better use of the space than the vertically oriented option. Both formats have their merits for sure, but it would be great to have the option for a horizontal legend in ArcGIS Pro (and some of the online apps).
