               String notes)

Parameters:

resultCount - number of data points to plot

smoothingCount - number of data points to keep for smoothing

startPercent - the start time as a percentage of the overall time

endPercent - the end time as a percentage of the overall time

handleToggle

public void handleToggle(ActionEvent e)

Handler for series toggle checkboxes.

Parameters:

e - the action event.
