Tutorial 116 demonstrated how to force a re-calculation of a number of charts at specific intervals. The tutorial uses some of the techniques from tutorial 115, in particular the use of the Timer to issue a RecalculateException at a specific time and then at set intervals after that.
The specific code used in order to refresh the program applied to a chart is:
Throw RecalculateException.Create( "Refresh" );
This recalculate exception reloads the program applied to the chart, but it does not reload the data.
Quick-tip 53 demonstrates how to reload the data on the chart by replacing the above with the following syntax to call a macro:
Value99 = runcommand( ".Refresh" );
When using runcommand the ‘Enable runcommand EasyLanguage keyword…’ check box must be selected in the format-analysis dialog box.
In addition, for the runcommand to work, the chart needs to be ‘in focus,’ i.e. selected.
