Power factor graph

[EduU]

I don't have knowlegde in ASCII, its hard to make it??

Maybe a help on that? =x

or How can I separe the plot in 2 plots one positive another negative... and than put them together in a new graph with a custom scale? is that right? I think I didn't understand it.

Hi EduU,

did you google for ASCII? It's an old standard for coding text... And it's the standard behind LabView strings...

Well, you can create more than one scale per graph. You can create more than one plot per graph. You can assign each plot to a different scale. You can change each scale to your needs. You can assign the same color to each plot. In the end it looks just like one plot with an "odd" scale jumping from 1 to -1...

Go and look at the examples coming with LabVIEW.

Well GerdW,

In my case I only have one plot how can I separe it?

I will need to separe the positive values from the negative one.

Hi EduU,

attached an example. You may have to do some modification to Y scales & plot colors, and maybe replace labels by (simple) strings - but the general idea is there...

Next time please try to do something on your own - I didn't do any comments to force you into "learning mode"

Well GerdW,

Thanks for the example

Now for sure I will try to understand and make my own solution!

Hey GerdW,

I was trying something here... and looking your vi....

I only need to know one thing know...

How can I put the 2 graphs "together" because I need a "continuos" graph

and in your case I have a graph that show me when the value is positive in top

and when the value is negative at bottom.

how can i take those 2 plots and put them in only 1 waveform?

Thanks

Hi EduU,

-you can create multiple Y axis for one graph

-you can plot more than one plot in a graph

-you can assign each plot to a different Y axis

So put multiple plots in a graph (as shown in the context help of the graph) and assign the plots (2 plots as in my example) to different Y axis. Now you only have to set the axis scaling as needed and you're done...

[EduU]

Well I understand that... but it gives me a graph like that:

and I can't have those empty lines =x I need a continuos graph

somethine like that: /\   /\   /\

                                  \/   \/   \/

Something like that!

Hi EduU,

one idea crossed my mind:

Insert points in both plots when the "1" value is crossed. Inserting the same point in both plots will make them appear as one line in two colors...

[EduU]

well I understood,but how can i make that?

I tried here but don't work x(
