How to create varying color outline symbology only?

[RangerofGIS]

hello I have about 100 unique values that I would like to have represented all in different outline colors but for all of them have "no color" as the polygon fill.

I know how to do this 1 by 1, but I'm trying to find a way to do it on mass.

When using Unique Values for your Primary Symbology, click on the Settings symbol to the right of the Color scheme to access Color Scheme Options. Check Apply to Outline. Then in the Classes tab, click on More to access Format all Symbols. Under Properties/Appearance, select No Color and then select the desired Outline width and click Apply.

Hi,

I think, if I'm understanding you correctly, you just need choose "Apply to outline" in the settings dialog, next to the Color Scheme dropdown. You can increase the width of the outline but choosing "Format all symbols" from the More dropdown on the Classes tab.

Does that work?
