If there is a product change associated with the variable, the dash lines appear modified, indicating the upper and lower reject or warning limits of the variable value for the new product.By default, the sparkline plots a line graph based on the variable values trending four hours before and after the variable value on which the alarm was created. The actual variable value on which the alarm was triggered is indicated by a red dot.Note: You set the duration of the time range for the variable value in the
