Failed to plot multiple plots

Solved!
Go to solution

Hi all

 

I'd like to plot several values through time in one graph/chart (i always forget which one i need).

Now I've set up an example of how I want my interface to look like, but when I plot the data, instead of each datapoint having a different line, they just represent as one point in the plot. (see images for more clarity.)

 

There's also a bit of double work i think, if someone could help me solve this aswell, but the main problem is the graphs/charts

Hi Xebe,

 

did you read the context help for charts? It explains how you need to present your data!

 

For several plots in a chart you either need to provide a 2D array (plots per row) or an array of clusters:

(As a Dutch guy you probably can read the German text… :D)

So how would I get the 2D or array of clusters starting from what I have now?

And I'm belgian not Dutch, makes it even eassier to understand some German.

 

 

Edit:

 

I need the plots per parameter, so per Temp, pressure and flow. Which I first have to extract from the cluster i already have

Hi Xebe,

 

how would I get the 2D or array of clusters starting from what I have now?

How to create a cluster is shown in the context help. Building an array of clusters is easy with a BuildArray node…

The same applies to arrays: you already know how to build a 1D Array. What happens when you again use BuildArray on your 1D array?

(This is pretty basic LabVIEW stuff so I guess you know the answer! :D)

 

And I'm belgian

The words are so similar… 🙂

Best regards,
GerdW

So now I have this:

graphs 3.jpg

That's a step closer to what I wanted, however, how do I add a legend to it so that I know which colour represents what?

And I want to split per parameter (so temp, pressure and flow)

 

 

FYI: Also we speak and write the same language, it's just a different nationality 😉

 

 

EDIT:

 

Okay fixed it, the solution lies in my own answer 😛 for the different parameters part

only gotta find how to add a legend now

 

EDIT 2.0:

Found the answer again 😛 resizing is always an option apperently.

 

Well thanks for the help 🙂

Hi Xebe,

 

there already is a legend!

All you need to do is increase the number of shown plots: use the mouse (in edit mode)… 😄

I noticed 😄 but thanks for reminding me.

(I was confused by the 'autosize plot legend')

 

Edit:

 

Did something wrong, I want the bottom type, but the top one somehow changed :s

Edit 2.0:

The overlay function 😛 found it again. I'm a mess
