Suppose there is a csv file that contains columns time,x,y. And at specific instant it is required to mark a point in the y vs x graph. This point keeps changing as one keeps reading row after row. Like you read a row and mark a point then you read next row and mark a new point with the time column being taken into account. Like if you read a row with time 2s and you mark it and then a row with 4s as to be marked exactly after 2s of the first one. How could this be done?

Is there any function for that?

What I have tried:

I have tried to plot it but i am able to plot only the entire y vs x graph not instant after instant

It is done as you describe ... read a row and mark the point, read next row and mark next point, etc.

## Solution 1

You may have to introduce a pause between each read/draw, otherwise the whole process may be too quick for the human eye to be able to differentiate the distinct steps.
I would try with a pause between 0.1 and 0.3 second, and see if that fits.
