Power factor graph

[EduU]

Well guys, I want to know if labview have a graph specific to Power factor... or if I can do one...

For the people don't know.. Power factor can goes to 1 to -1

But is something like that:

0 

-0,5

-0,8

-0,99

1

0,99

0,8

0,5

0

I can make it at Y scale??

I tryed here but I didn't make it work!

Thanks

Hi EduU,

you can set the scale of your plot to the range you need. Use a property node. First select the active YScale and then set min and max.

Well Mike, the problem is because my max and min is 0

but like one is the "negative" 0

maybe it works? I will try it.. and post here if solved my problem!

Thanks for help

Hi EduU,

this isn't the first thread where you're asking for this topic, right?

Well, your best bet is to use some kind of text display (array of strings, picture indicator, etc.) to show your text to mimic the Y scale. Set the actual scale using property nodes and hide it from the user...

[EduU]

Well GerdW,

I didn't understand..

why use a text? could you make some example for me??

and yes, isn't the first time x(

Hi EduU,

so please stay in your original thread or give (at least) a link to it, so others may know what has been suggested before!

LV doesn't allow for a kind of scale that you're asking for. The scale has to be "monotone", i.e. constantly rising values. No way to make it jump from "+" to "-" and back. At least not using numbers. But: when using strings you're free to type whatever you want...

[EduU]

In the original thread no one help me with that.... It was another problem... and after I solved it I ask for that... I know LabVIEW don't have that scale I want... but how can I use a string as a scale?

Using property node... Y scale and use string?

I already look a lot of programs that show this power factor graph and all is on the same way

My axis is on 1 and not in 0 like usual.

When the number is down 1 its negative going to -0,99 to -0,01

and when the number is up the 1 its positive going 0,99 to 0,01.

But I only don't know how to make it in LabVIEW....

with string maybe it works... but I need to see a short example.... could you give me it?  Thanks

Hi EduU,

maybe later, busy working now...

You may stack two plots with their own scales on top of each other as a start...

[EduU]

Ok Gerdw,

I will try here and I will see if I can make it works...

When you have some free time you do it =D 

Don't worry 😉
