6.1.7 Vector Plot
Like the Profile Plot, the Vector Plot gathers results from multiple
measuring points, and is thus available only when measurements are
performed in a traverse mesh.
Unlike the Profile Plot however, the Vector Plot presents results in a plane
rather than along a line, and thus requires that both the horizontal and the
vertical axes of the plot correspond to two of the traverse axes X, Y or Z.
Since furthermore the Vector Plot shows mean velocities only, it is the least
versatile of the plot types offered by the Advanced Graphics Add-On, but at
the same time unique in its ability to give an overview of the overall
behaviour of the flow measured.

Property group ‘Data’
Figure 6-31 shows an example of a Vector Plot, showing mean velocities in
a large area of the flow around an circular cylinder located with it’s axis in
position (x,y) = (20,0) mm. The reversing flow for x < 40 mm suggests the
presence of vortices behind the cylinder, and it appears that the reattachment
point lies at between x = 40 and X = 50 mm, y = 0.
All other figures shown in section 0 of this text, refers to this example.
The property group Data shown in Figure 6-32 contain the properties that
are specific for the plot type Vector Plot.
