The 2D Plot is a point-based plot, presenting results from measurements
and/or calculations performed in a single point. If measurements are made in
a traverse mesh, you can step through the different measuring positions, but
the results must be viewed one at a time unless you create multiple 2D Plots,
each showing data from a different measuring point.
This may seem a limitation, but it also makes the 2D Plot one of the most
versatile plot types, since you can freely determine which data to show on
both the horizontal and the vertical axis of the plot. In the other plot types
(Profile and Vector Plot) one or even both of the axes must correspond to a
traverse axis X, Y or Z. With the 2D Plot the only limitation is that data on
the horizontal axis must be somehow related to the data on the vertical axis:
For example it is not possible to show velocity samples from one LDAchannel
as a function of arrival times from another LDA-channel.
(Obviously this makes no sense anyway so this is not really a limitation).

Configuring the 2D Plot
Figure 6-13 shows an example of a 2D Plot, where velocity samples from a
periodic flow are shown as a function of their arrival time.
All other figures shown in section 6.1.3 of this text, refer to this example.
The configuration of a 2D Plot is used to determine which data to plot. To
configure a 2D Plot, you simply select the plot, and then right-click inside
the plot window. This will bring up a configuration dialog similar to
Figure 6-14 showing the data available for plotting.
Note If data is not yet available (i.e. measurements have not yet been performed),
you will get an error message trying to configure the plot unless system
setup has progressed so far that the type of data can be predicted.
