Chart provides detailed diagnostics using an error log file. When an error
occurs and the error log feature is enabled, XY Chart first creates an error log file
if does not already exist, and then writes the error details to the file. Only one log file is
created and updated for each
application using one or more instances of this control. The name of
the log file is XYChartErr.Log and it is found in the directory where the
compiled application is run. Here is a sample of an error log entry:
8/9/2003 7:54:53 PM Error message: (ChartData) Y data not numeric.
Defaulting to 0. (Error data
at index: 3, row: 32)
format of the error log is as follows:
Programmatically set the LogFile property to configure and enable this feature.
