marker position as the reference value. Thus, you can change the
trace scale by placing the reference line at the position indicated by
the main marker.
5. Press the Scale > Scale/Div, and input the desired value that
indicates the scale per division.
Scaling the Trace Based on the Top and Bottom Values
When the vertical axis is set to logarithmic, you can scale the trace by
specifying the highest (top) and lowest (bottom) values displayed within
the graph.
1. Activate the trace you want to manually scale.
2. Press Scale >Log-Y Top and input the desired value indicating the top
value to be displayed on the graph.
3. Press Scale >Log-Y Bottom and input the desired value indicating the
bottom value to be displayed on the graph.
Manually Scaling the Active Trace for a COMPLEX Z-Y Graph
Scaling the Active Trace for a Complex Plane
When your graph is a complex plane, you can manually scale the active
trace by specifying the reference values for the vertical and horizontal axes
as well as the scale per division.
1. Activate the trace you want to manually scale.
2. Press Scale > Reference X Value, and input the desired value that
indicates the reference value for the horizontal (X) axis. This value is
a real value. The reference line for the horizontal axis in a complex
plane is stationary in the center of the axis.
3. Press Scale > Reference Y Value, and input the desired value that
indicates the reference value for the vertical (Y) axis. This value is a
complex value. The reference line for the vertical axis in a complex
plane is stationary in the center of the axis.
4. Press the Scale > Scale/Div, and input the desired value that
indicates the scale per division. For a complex plane, both the
vertical and horizontal axes use the same scale per division.
Scaling the Active Trace for a Polar Chart
When your graph is a polar chart, you can scale the active trace by
specifying the full scale value, that is, the distance from the origin to the
outermost circle.
1. Activate the trace you want to manually scale.
2. Press Scale > Divisions, and input the desired value that indicates
the full scale value. Divisions defines the number of divisions on the
Y-axis. An even number from 4 to 30 can be used.
