Change the interval for a graph by choosing values from the Hours and Minutes drop-down list boxes. If necessary adjust the width and height of the graph and then click the update button. The changes to the time span apply to all the graphs on the Graphs tab but have no effect on the graphs on the Monitor tab.

To change the graphs both here and on the Monitor tab use the configure graphs link on the top right. This opens a dialog box for setting the default interval for the x-axis. Save any changes that you have made and the values chosen will be the defaults whenever you log in. You can also change the defaults from the Monitor tab as described in The Server Graphs and Critical Events; defaults for other users will be unchanged.

Use the reset button to restore the default value for the interval. Doing this will also reset the default size of the graphs.
