How do I reduce columns to say, every 5th row only.

[marty0750]

I have this selection of data for every one minute of time. But I want to eliminate every four rows so that that I have data for only every 5 minutes as example on right.

Please reformat by indenting the data table by 4 spaces. Thanks.

Edited the question (as OP needed to do, instead of posting new question to make it tidy; would you give birth to a new child every time your existing child’s clothes gets dirty? :-)) to format it properly, and moved image from the second (now removed) question here.

@marty0750: to format your data, use the preformatted text toolbar button. To insert an image (as opposed to link), use relevant toolbar button (or prepend the generated link with !, as in ![link text](http://url)).

Is this question a duplicate of your own question from 2 years ago, already answered by @erAck?

How about that. So i did! Can;t recall if I succeed though. Maybe that’s why I ask again. I’ll go back over it and see how I go.
