Plot array to waveform graph

[johnny az]

Hi, I have an array that I wish to plot it into a waveform graph. I tried experimenting with the Build Waveform function and some others but could not get anything out of it. And how do I choose which points I wish to plot on the graph?

Thanks in advance.

It depends on your data.  If you are always sampling at 5 seconds, you can use Build Waveform.  Wire the dt for 5 seconds and index the columns you want.  Otherwise, you will need to use an XY graph.

Hi man thanks for your help. I tried your example, but couldn't get the expected waveform. I attached an excel file on how the waveform should look like. Really appreciate it if you can help me.

Possible repost?

Anyways try the attached VI. I am not sure what you mean by intensive. This will extract data from your text file and do everything automatically for you.

Hi Ace. Is there any simpler way to implement this program? Without using any loop or structure.

Anyway Ive tried your suggestion but when I change the graph's scale, it will not display any waveform.

The scale that I wish to use are:

Y axis - Automatic Formatting, Minimum 0, Maximum 60, Offset 0, Multiplier 1

X axis - Relative Time, Minimum 0, Maximum 86400, Offset 0, Multiplier 300

When I try to instill this properties with your suggestion, it doesn't display any waveform and I'm not sure why.

But I would really appreciate it if we can come up with simpler program, like I mentioned. Preferably, with what I already have as a base. (The VI I attached above).

Many thanks, best regards.

Simple Attached.

A million thanks my friend. We're almost there. It''s just that I thought by having the plot visibilty checkbox, I can choose which plots to display. But fact is, it's only displaying two plots, even though I checked all the boxes.

Another question, what does the constants 5 and 6 on the index array represents? 

[.aCe. · Accepted solution]

You have only wired 2 signals, hence just the two signals. If you need more, expand the merge signals node and wire more signals to it.

5 and 6 are the column numbers for Poly_M_Tem & TF_M_Temp, I had to delete the first column as this was the time stamps and it was not required. Hence it is different from your 6 & 7.

Hope that makes sense.

I got ittttttt. Thanks a million ace!!
