Ÿ Resistance Assign resistance data to the y2 axis.
Ÿ Power        Assign power data to the y2 axis.
Ÿ Source       Assign source data to the y2 axis.
Ÿ Formula    Assign formula (arithmetic operation result) data to the y2 axis.
Ÿ Any             Assign multiple data type to the y2 axis.
You can set different data types to the y2 axis in Details Setting.

Series Group

Select Series Selects the current active series. This combo box shows a list of all added series.
You can add extra series using the + button.
Y Axis Selects the Y axis for current selected series:
Y1     Assign the Y1 axis.
Y2     Assign the Y2 axis.
Data Selects the Y data.
This combo box shows a list of Y1 or Y2 Data Type data ( depending on the Y Axis selection ). If the Y1 or Y2 Data Type is set to "Any", all Voltage, Current, Resistance, Power, Time, Source, and Formula names will be listed.
To disable the XY plot line, select "Not Set".

Reference Group

Resave/Save Resave overwrites saved reference data.
ŸThis selection is only available when reference data is saved.
Save creates a snapshot of the current data and saves it as reference data.
ŸThis selection is only available when no reference data is saved.
Clear Clears reference data if there is any reference data saved. .
Reference Line Shows/hides the reference line.
This combo box displays all reference line.
The number of reference line will tally with the number of series.

Marker Settings

The following describes the marker settings:

  1. Focuses is on the current marker. Focused marker can be moved by mouse. The following operations are valid:
    • Clicking the Plot Area moves the active marker to nearest data point of the target series.
    • Click and Dragging in the Plot Area moves the active marker to nearest data point of the target series while dragging.
    • Click and Dragging the diamond marker annotation moves the active marker to nearest X or Y data point of the diamond marker annotation while dragging.

  2. Shows/hides the marker in the Graph.

  3. Selects the series that the marker focuses on.

  4. The X value for current marker position.

  5. The y value for current marker position.

  6. The Index of current marker position.

  7. The difference between marker 2 and marker 1 for X and Y value.

When the graph view is updated and a series line is shifted, the marker will not trace the moved measurement point. After the graph view is changed, click the plot area to move the marker to the measurement point.
