Chapter 26.  Drawing Charts  >  Administering Charts

Administering Charts

You can use ColdFusion Administrator to specify the number of charts to cache, the number of charting threads, and the disk file for caching images to disk. When a chart is created, ColdFusion caches it by using the Administrator cache settings. Therefore, when a repeated request is made for the same chart, ColdFusion looks in cache and loads it from there instead of rendering the chart again. You can make changes in the cache setting in ColdFusion Administrator. Figure 26.13 shows the ColdFusion page for changing the cache settings. You need to select the Charting option of the Server Settings menu on the left panel of the ColdFusion Administrator page.
