Graph control:
Auto Scale icon will change the graph scale automatically to fit the trace in the graph. The right
arrow button opens the menu for enabling or disabling the run time auto scaling. This function is set
independently for the X and Y axes. If this function is enabled, the graph scale will be changed
automatically to fit the trace in the graph during the measurement.
Zoom In icon zooms the data graph in. This enlarges the trace in the graph. Then the center of
zooming will be the cursor position.
Zoom Out icon zooms the data graph out. This reduces the trace in the graph.
Graph Setup icon opens the Graph Setup dialog box used to change the graph axis setup.
Choose Active Y axis icon selects the Y axis that is effective for the analysis tools (marker control
and auto scaling).
If multiple layers are opened on the Data Display window, the scale change is applied to the layers.
This means that the X-Y graph scale will be shared by all display layers. The auto scaling is
performed as follows.
1. Graph scale is optimized for the data on the selected layer (top layer).
2. The graph scale is applied to the graph in the all layers.
Note that auto scaling is performed independently for the left and right Y axes.
There is also a function for resetting the graph scale. Click View > Cancel Scaling > This Display or
All Displays.
This Display will reset the selected layer only. All Displays will reset all display layers.
