Drawing thematic raster datasets representing continuous data
The Classified method displays thematic rasters by grouping cell values into classes. It can be used to represent continuous data, such as elevation.

Having current statistics improves the renderer's ability to display the raster accurately.
Steps:
- In the table of contents, right-click the single-band raster dataset layer that you want to display by grouping values into classes, and click Properties.
- Click the Symbology tab.
- Click Classified.
- Optionally, if your raster dataset has a value attribute table, click the Value drop-down arrow and click the field you want to map.
- Optionally, click the Normalization drop-down arrow and click a field to normalize your data.
- Click the Classes drop-down arrow and click the number of classes you want.
- Click Classify and choose the classification method you want to use. Click OK to close the Classification dialog box.
- Click the Color Ramp drop-down arrow and click a color ramp.
- Optionally, choose a color or No Color to display any NoData values.
- Click OK.

Use the Image Analysis window or Effects toolbar to interactively adjust a raster layer's transparency over other layers on your map.

You can quickly change the colors applied to a raster by clicking the color in the table of contents.
