labview graph from excel data

[agyna]

Hello,

I need some help. I have data in excel The first column is a timestamp and the other columns are the data needed.and I am trying to get a graph with multiple plots with these data.

attached here are the excel file and a labview file. In the labview file, the top part is an example I got from the forum, an interesting graph I am trying to follow.

The bottow part is my tentative to extract the data from excel into array and try to use it. but I am stuck here. Any help please!

Thank you,

Agyna

Hi agyna,

I've saved xls file into csv and then i'm reading into labview and plotting the graph. Please check it this is what you need.

Thank you for replying. One thing that is needed is to used my own timestamp that is in the first column of my data. I just removed the top part that was creating the time stamp, but then I don't know how to extract my timestamp from the first column of my excel data and use it for the x axis.

Please see attachment, I removed the top part of the program.

Thank for you help again.

Hi,

This link doesn't really help solving the problem. As you can see in the attached file I have extracted the timestamps into an array, but I am not sure how to use it for the graph.

Thank you.

Please check this. I didn't do it for all graphs. I think you can extend the same and expand for all plots.

Hi,

Could some please take a look at this. It is working for about 50 plots on the same graph. But with the attached excel file we need to have about 500 plots on the same graph and analyse them. Can someone help me here on how to add the other plots as my "build Array " element is getting longer and longer as I am adding more plot.

Any idea on how to use some loops or something else to have this done easily?

Thank you

Sorry I couldn't attach the original excel file. The attached file is just for 120 plots on the same graph, so same Idea.  I need some help please.
