zoomed part of graph into a table: a how-to-question

Hello,

Could anyone offer some help as to how to make a table from only the zoomed part of a graph, which also includes the index and data columns? For this one analysis, I only need a small range of points (~50 or so) from many waves, but this range has variable start points for different files...so I thought that if I could plot the waves, zoom in on the region, (if needed put cursors A and B onto my region of interest) and then extract that info into a table....life would be so much easier!!!

Any suggestions would be greatly appreciated!! Thanks so much!

Sincerely,
Bill
A table will not display part of a wave, just the whole wave, so if you really want to display only part of the wave in the graph then you will have to create another wave containing just the points you want in the table. You can do this with the Duplicate operation.

You might be able to use the GetAxis operation to determine the extent of the X axis and from that determine what points you want to view.

I have put a quick first cut at this in the snippets area.

Totally awesome! Thanks so much hrodstein!!! Yes, it totally works for making data tables of a zoomed portions from graphed waveforms. If I knew the programming language better, then I should have specified that the graphs are made of XY pairs. How would you modify your code to produce a data table from a zoomed portion of a graphed xy pair? I've tried all day trying to figure it out, without any success except to make blank tables. But I have learned a few things from trying; none of which have helped me right now. Any suggestions would be greatly appreciated!!!

Sincerely,
Bill B
