Graph Controls

Graph Toolbar

Each graph view has a toolbar with several options to control the entire graph. Other than the Bar Graph which offers a slightly different set of controls, all graph types offers the following controls:

Graph Toolbar

• : The Measurement Marker icon triggers adding a measurement marker line to a view. See the Measurement Marker Feature topic.
• : The Groups toggle button associates or disassociates this view within a specified group. See the Groups Feature topic.
• : Use the Align Horizontal Center in Group button (available on some graphs) to cause all the views in the group to use the same horizontal center as the current view.
• : Use the Align Horizontal Range in Group button (available on some graphs) to cause all the views in the group to use the same horizontal range (left and right values) as the current view.
• : The Zoom In button increased the graph resolution to provide more detail by the set zoom factor and zoom directions. Alternatively, you can press the ALT key and drag the mouse on any graph area of the graph.
• : The Zoom Out button to decrease graph resolution and see more data using the set zoom factor and zoom directions. Note: The Zoom Options help you control the display by specifying what combination of graph axes and resolution factors to use.
• : Use the Zoom Options button to reset the zoom for the graph (return to original zoom factor and orientation). Use the drop-down selection arrow next to the button to specify the zoom factor and X-Y directions. State, Bar, and Discrete graphs can only adjust zoom in the X-axis direction.

• : The Refresh button updates the view as soon as pressed. Otherwise views are refreshed periodically as often as "Refresh rate" property is set to.
• : The Find button displays the Find dialog to search for a specific event or value. See the Find Feature topic.
• : The Filter toggle button enables/disables the filter and also displays the Filter dialog after enabling filter. See the Filter Feature topic.
• : The Freeze Update button suspends the view's data refresh. Click again to resume the data refreshing at the defined interval.
