[Paraview] CSV data display

Fri Apr 19 12:06:26 EDT 2013

I agree that would be useful.

Another workaround is to write each timestep to a separate csv file and label it in a time series, I.e. data_0.csv, data_1.csv, …, data_N.csv where N are the timesteps.  When you open the file series, paraview will read it in as a time series and animate it.

Hi all,
Many thanks for the tips.
I am still having trouble in executing the task.
It would be nice if there is a way to just select a column from the table and hook it up with animation tool.
In the table to points approach, we get option to select x, y, z columns. Why not have an option to select for time and any attribute for coloring (which I think it is already there).

Thanks
Venkat

I struggled with the Threshold filter on Table To Points for a while before realizing that the Table to Points is a 1-cell grid with all points in that one cell. The Threshold filter on time will not work in that case because the threshold will either turn all the points on or off.

You can work around this by using the Delaunay3D filter on the Table to Points object to turn your data into an unstructured grid.  Then you can use Threshold on those grid cells and isolate (or animate) times.

Hope this helps.

Hi Venkat,

you can use the threshold filter to select a given time and create an animation cue that will change the threshold value (the time for you) so you will be able to use the time management of ParaView with your data in a somewhat transparent manner.

Hi,
I have a CSV data in which I have time, x, y, z and other attributes as columns.
I am able to load the data and followed the help to display the points. But I am trying to find a way to use time column to animate the particles?
Any ideas?

Thanks
Venkat
