Change Symbology with different Column Value

Question

I am using ArcMap 10.0.

I am trying to change Cadastre colours when the values of the box EXTRA is set to 0,1 or 2. So basically, I need the default values set to 0 (already completed). Properties that have to be invested have a value set to 1 (completed). Properties with further information needed value set to 2 (completed onsite).

To make it user friendly I would like to set up the symbology colour to change the polygons to different colours depending on the EXTRA value.

0 = clear 1 = green 2 = red

I have tried both Quantities and Multiple Attributes but neither get the result I am after.

Using the 'Graduated Colors', changing Fields Value to EXTRA only gives one symbol when I would want three? If I have three then I will be able to change the range and respective colours.

Answer 1

So, you have a polygon feature class where you have multiple polygons. Each polygon has a value stored in the field named Extra. You want to show polygons with unique colors.

You should use the Unique values symbology in ArcMap. You can then choose what color your polygons with a certain value will show.
