functionality on the graph

Solved!
Go to solution

Hi, Hello, I am developing data acquisition code on labview and I would like to add functionality, I display my data (2 parameters) on a single graph; I want to display the min, max and average of each parameter, I tried with propery node but it only displays the max and min of one of the data (the most important)? how can I fix this

and the second question, could I use code to change the scale of my graph so that, if necessary, I could have more detail on the graph?

thanks in advance

By writing "working code according to the requirements".

Yes.

 

General suggestion: when we should discuss problems in your code then you should attach this code…

Hi amel,

 

when using recent LabVIEW versions you should downconvert your VI before attaching. (File->Save for previous)

 

Most say "for LV2021 or older", I prefer LV2019.

Best regards,

You can have a routine to find the max, min and average of the data, then plot them together. but depends how your are ploting them, You can plot htem as waveform and as a chart .

Please save your code for labview 2020.

You have two main choices:

 

  1. Create additional waveforms with constant values and display them as additional plots
  2. Create horizontal cursors and place them at the min/max/mean, etc. for each plot.

 

Here's a subVI that would process one waveform to create the others for max,min,mean (case 1), call it for each.:

And here's how you could set the cursors (make sure you define 6 cursors first)

Many years ago I made an XControl that has over/under limit highlighting (it's one of my early XControls, so it's not so polished).  Maybe you can use that as a guide to build something.

There are properties for auto-scale, min and max of the x and y axis and they can be modified via the relevant property nodes. Of course you should turn off autoscaling when setting defined min and max, else it is futile.
