Use advanced labeling for a continuous raster dataset

When using the stretched renderer, you can use advanced labeling to better convey the data that you are displaying. Advanced labeling allows you to set your own labels and create your own color schemes. You can set your own labels so that users can see where particular values are located along your color scheme. Once you set your values, you can choose an existing color scheme or create your own.

There are three ways you can set your customized labels: number of intervals, size of intervals, and customized values. Setting the number of intervals allows you to specify the number of class breaks in your labeling. Setting the interval size allows you to determine the equal interval class breaks in your labeling. Setting custom intervals allows you to specify which values are labeled on your color scheme.

Once you have set up your labels, choose the color scheme. To create your own color scheme, click each color patch and edit it to establish the color for each value. As you edit each symbol, the color scheme automatically interpolates the colors between two color patches. There are three methods for setting advanced labels:

• Label by number of intervals
• Label by interval size
• Label by custom values

Note:

Advanced labeling options are only available with the stretched renderer. The minimum number of intervals (or class breaks) must be 2 or more.

Label by number of intervals

Setting the number of intervals allows you to specify the number of class breaks in your labeling.

1. In the Contents pane, select the raster layer you want to display with an advanced legend.
2. On the Appearance tab, click the Symbology button.
3. In the Symbology pane, choose Stretch.
4. Optionally, if your raster dataset has multiple bands, choose the band you want to stretch.
5. Click the Advanced Labeling tab.
6. Click the Number of Intervals button.

   This option labels the color scheme based on the desired number of interval breaks.

7. Type the number of intervals in the text box and press Enter. The minimum value is 2; therefore, three values appear in your color ramp: the minimum value and two additional class breaks.
8. Optionally, double-click a label to edit it.
9. Choose the appropriate color scheme.
   • Choose an existing color scheme from the Color scheme drop-down list.
   • Double-click the color patch and choose a color for that value. The new color is reflected in the color scheme.
10. Click Apply to accept the labels and color scheme.

Label by interval size

Setting the interval size allows you to determine the equal interval class breaks in your labeling.

1. In the Contents pane, select the raster layer you want to display with an advanced legend.
2. On the Appearance tab, click the Symbology button.
3. In the Symbology pane, choose Stretch.
4. Optionally, if your raster dataset has multiple bands, choose the band you want to stretch.
5. Click the Advanced Labeling tab.
6. Click the Interval Size button.

   This option labels the color ramp based on the desired equal interval break.

7. Type the interval size in the text box and press Enter.
8. Optionally, double-click a label to edit it.
9. Choose the appropriate color scheme.
   • Choose an existing color scheme from the Color scheme drop-down list.
   • Double-click the color patch and choose a color for that value. The new color is reflected in the color scheme.
10. Click Apply to accept the labels and color scheme.

Label by custom values

Setting custom intervals allows you to specify which values are labeled on your color scheme.

1. In the Contents pane, select the raster layer you want to display with an advanced legend.
2. On the Appearance tab, click the Symbology button.
3. In the Symbology pane, choose Stretch.
4. Optionally, if your raster dataset has multiple bands, choose the band you want to stretch.
5. Click the Advanced Labeling tab.
6. Click the Number of Intervals button.

   This option labels the color scheme based on the desired number of interval breaks. The minimum value is 2; therefore, three values appear in your color ramp: the minimum value and two additional class breaks.

7. Double-click a value in the table that you want to edit. Type the custom value in the text box and press Enter.

   You cannot edit the minimum or maximum value.

8. Optionally, double-click a label to edit it.
9. Choose the appropriate color scheme.
   • Choose an existing color scheme from the Color scheme drop-down list.
   • Double-click the color patch and choose a color for that value. The new color is reflected in the color scheme.
10. Click Apply to accept the labels and color scheme.
