Graph
You can configure the following settings that affect how readings appear on the Graph screen.
Window position and zoom:
Specify the readings that are displayed on the screen.
Current and voltage auto adjustment:
Automatically adjust the scale and offset of the Y-axis.
Current and voltage manual adjustment:
Manually adjust the scale and offset of the Y-axis.
Changing the window position and zoom
You can use window position and zoom to specify how the readings are displayed on the screen.
For the power supply function, use window position to set the center point of graph. Use window
zoom to specify the number of readings that can be displayed.
For example, set the buffer size to 100. A position of 25% means the 25th reading in the buffer is the
middle of the point in the plot. A zoom of 50% specifies 50 readings shown on the screen. For details,
see the following figure.
