k Displaying Plots on T-Y Coordinates and T-X Coordinates (AXTRANS
Screen)
As can be seen on the plot list screen, the data for each plot includes X and Y-coordinates, as
well as a time value T.
On the Picture Plot screen each plot is normally displayed as coordinates (X, Y) on an X-Y
plane, but time value T can be used to display plots as coordinates (T, Y) on a T-Y plane or as
coordinates (T, X) on a T-X plane.
Under initial default settings, time values are 0, 1, 2, and so on (arithmetic progression with
a start value of 0 and a step value of 1), in accordance with the sequence that the points are
plotted. You can change the T value assigned to each plot by changing the start value and
step value.
T-Y coordinate plots and T-X coordinate plots are displayed on a special screen called the
AXTRANS screen. The AXTRANS screen simultaneously displays the X-Y coordinate plots
and the T-Y or T-X coordinate plots as shown in the example below.
