LabView Plotting Datetime from CSV: Format Issues

[EnzoC]

Hello everyone,

I am running into Problems with the formats of my X and Y values for the XY Graph. I am reading values from a CSV file which include 3 columns per row, seperated by a comma. I managed to read from this file and Output the values but I want to plot them also. My Problem is that i can not get my datetime, which currently is a string into a plottable Format. What can I do?

The files are attached below.

Hi Enzo,

read the files as strings, convert timestamps and measurement data seperately:

Dear GerdW,

I tried to use Your solution but I get an error.

The error is at the search in string function due to an invalid Input Parameter.

My VI is attached.

Also You copied the values of the CSV into Labview, I want to open them in the Program as new values will be added later -> Live Plot

Hi,

The error is caused by the Index Array calling the first Column, whereas the Date/Time is in the first Row.

You will need to change the Input to the other terminal, that should work.

Hi Nico,

the error is fixed, it plots, but in this Format: 3,57476E+9

Is my Format string wrong?

I fixed the error by not transposing the Array.

Hi,

That is just a configuration for the Graph. It is currently set to numerical values as the timestamp is a numerical count in seconds. You will need to change the X-Axis to Absolute Time under the Properties for the Graph.

This worked, example solution for everyone!
