Default How to plot streamlines on a slice?

How can I plot streamlines on a slice? I only found ways to enable contour or vector plots on a slice.
I've managed to do this in CFD post (see attachment), but because my dataset is too big now CFD post is unable to handle this. Hence I switched to Tecplot 360.

How can I achieve a similar looking visualisation in Tecplot 360? The attachment shows what my goal is. The image shows the streamlines colored by velocity on three different bounded planes.

Streamlines are integrated on U V W vectors so naturally they won't constrain themselves to a slice.
One way to work around this is by forcing one of your Vectors (for example W) to zero. This really only works if you're looking at slices in the principle axis.

If you want streamlines on a Z slice, you can go to calculate variables and create a new variable = 0. Then under Vectors, set X to U, Y to V, and Z to your newly created variable which should be zero.
Now show your slice and seed streamlines on that slice. Because Tecplot now thinks that your Z component of your vector is 0, the streamlines shouldn't deviate out of the plane.
Take caution however, because your Z component is not the true component value, the streamline integration might not be entirely accurate.
