LabVIEW Waveform Chart

[AndrewIons01]

Hi All

I am plotting some data values from an image centroid position but I want the show to show all of the data points and not just a window. 

I basically need the start to occur at 0 and the chart to juts keep adding points on.

Best Wishes

Yes.

What is the question?

(When you have problems with your VI then you should attach your VI…)

Hi GerdW 

Thank you so much for the reply, I will attach it. 

My question is this: How do I make the waveform chart display ALL data points both past and current when it is gathering data and not just a select few?

Charts store a fixed length that can be configured at edit time, for example by right clicking on the chart and choosing History Length (I think that's the name).

If you need to arbitrarily keep increasing the length, you'll probably need a graph instead (Chart!=Graph in LabVIEW).

However, remember that you have only limited screen resolution to show points on, and limited RAM to store data...

I had a look at extending the memory earlier, I don't recall it working but thank you for the suggestion. 

Would it be possible to use an X,Y Graph for this.

Hi,

is anyone having the same problem like me with message #3?

[AndrewIons01]

Are you unable to open the file?

[GerdW]

Hi Andrew,

yes, I cannot even download that file because "virus scan in progress".

It doesn't matter which computer I use or if I log in or not…

Edit: now at 14:25 I can download the file. Nearly two hours after you created the message…

Hi GerdW

I am not sure why this is, it could possibly be because of the file size?

I apologise for this. What can I do in the mean time?

Best wishes

Andrew
