<div>The equation x=1 is actually a plane in 3-space, not a line. So what you really want to do is intersect your contour with the plane at x=1. You can easily do this with the slice filter.</div>

</div>
<div>Next, select the resulting point with the "select points on" or "select cells on" tool (in the toolbar buttons right above the 3D view). Then add the "plot selection over time" filter. You should see the data you want in a chart. Now, just "save data"
and output as a csv file.</div>

<div dir="ltr">I can't seem to work out the proper sequence of filters for the following.<br>
<br>
I have a 2D triangular mesh with a time-dependent scalar field, say phi. I want to generate a single isoline, say phi=0, which I can do with the contour filter, but then I want to generate a single point by intersecting the isoline with a vertical line, say
x=1. Then I want to save the time series of that point, which would look something like t_0, 1, y(t_0), t_1, 1, y(t_1),...,t_n since the x-coordinate doesn't change.
