Save a process history chart

When you save a process history chart, the chart is saved with the time in the Time Scale tab of the Configure Chart dialog. For example, suppose you configured a chart with a one hour time span starting at 9 AM and then shifted the chart forward to the current time of 11 AM. If you then save, close, and reopen the chart, the time scale shows the configured time of 9 AM to 10 AM.
