A histogram computed in the Symbology tab is not persisted with the raster dataset

Last Published: April 25, 2020


Some settings in the Symbology tab require that a histogram is built (e.g., using the Classified renderer, or using a histogram stretch). If a histogram is not present, ArcMap prompts the user to compute the histogram.

If a histogram is computed, that histogram is not persisted in the raster dataset; it is only persisted for that particular ArcMap session. The next time the same raster dataset is used in a new ArcMap session, the histogram must be computed again.


This is caused by a bug that affects the histograms for the IMG and TIFF formats in ArcGIS 9.3.


To persist the histogram in the raster dataset, calculate the statistics for that dataset using the Calculate Statistics geoprocessing tool.

  1. Open the ArcToolbox window.
  2. Navigate to the Calculate Statistics tool > Data Management Tools > Raster toolset > Raster Properties toolset.
  3. Double-click the Calculate Statistics tool.
  4. For the Input Raster Dataset, select the raster that is not persisting its histogram. Navigate to the raster dataset on the disk; it is not possible to drag it from the ArcMap Table of Contents.
  5. Leave all of the other parameters as their defaults and click OK.

    This raster dataset can now be used without the histogram issue.
