Export to CSV file

[kukiwakame]

I want to output the results of the EM simulation "EM U(t)" as a csv file, but I can't save it.
Please tell me the reason.

Thank you in advance.

# Adding a new PlotViewer
  inputs = [em_sensor_extractor.Outputs["EM U(t)"]]
  plot_viewer = analysis.viewers.PlotViewer(inputs=inputs)
  plot_viewer.visible = True
  plot_viewer.ExportToCSV("C:/Temp/test.csv")
  plot_viewer.UpdateAttributes()
  document.AllAlgorithms.Add(plot_viewer)

you need to call plot_viewer.Update() before exporting to csv

the method returns False if you have not updated the viewer... (btw, I agree this is a bit unintuitive, the ExportCSV could do the update ...)

In general

• UpdateAttributes() just does a "meta-data" update, e.g. to initialize options
• Update() is the actual update call. It executes the main work of the filter, viewer, exporter, etc.
