[Paraview] Help with producing a X Y plot of a scalar

[Nikolaos Beratlis]

Hi,

I have a cartesian grid and two scalars U, W that I read into paraview as
follows:

<?xml version="1.0" ?>
<!DOCTYPE Xdmf SYSTEM "Xdmf.dtd" []>
<Xdmf xmlns:xi="http://www.w3.org/2003/XInclude"; Version="2.2">
  <Information Name="MetaData" Value="ID-23454"/>
  <Domain>
    <Grid Name="Eulerian Grid" GridType="Uniform">
      <Topology TopologyType="3DRectMesh" NumberOfElements="   202   100
100"/>
      <Geometry GeometryType="VXVYVZ">
        <DataItem Dimensions=" 100" NumberType="Float" Precision="4"
Format="HDF">
         ../grid3dc_vxvyvz_VP.h5sp:/X
        </DataItem>
        <DataItem Dimensions=" 100" NumberType="Float" Precision="4"
Format="HDF">
         ../grid3dc_vxvyvz_VP.h5sp:/Y
        </DataItem>
        <DataItem Dimensions=" 202" NumberType="Float" Precision="4"
Format="HDF">
         ../grid3dc_vxvyvz_VP.h5sp:/Z
        </DataItem>
      </Geometry>
      <Attribute Name="U" AttributeType="Scalar" Center="Node">
        <DataItem Dimensions="  202  100  100" NumberType="Float"
Precision="4" Format="HDF">
         ../oy_tmavg_cyl2car.h5sp:/var3d
        </DataItem>
      </Attribute>
      <Attribute Name="W" AttributeType="Scalar" Center="Node">
        <DataItem Dimensions="  202  100  100" NumberType="Float"
Precision="4" Format="HDF">
         ../oy_tmavg_cyl2car.h5sp:/var3d
        </DataItem>
      </Attribute>
   </Grid>
  </Domain>
</Xdmf>


I then multiply U*W using the calculator to get a new variable UW. What I
want to do is create a scatter plot of the variable UW at a particular a
slice in the domain where in the X-axis I have U variable and in the Y-axis
I have W variable. The end result would like this


​
Paraview has a function called scatter plot but it only allows to specify
one axis, the X-axis data. How can I specify the Y-axis to be a different
variable?

Regards,

Nikos
