How do I creater a indicator to read power factor

[Fire118]

The problem that I have is not that I can read power factor because our RTU gives me a analog input in numeric fomat for our power factor. I need to know if there is some sort of scaling or indicator ( such as a analog dial type gauge) that can be scaled to read power factor in the below format. We want to see Lag / Lead that mimics our mechanical analog meter at the power plant. Any suggestions?

-0.5

-0.6

-0.7

-0.8

-0.9

1.0

0.9

0.8

0.7

0.6

0.5

Why not just use the dial or guage in the Numeric Controls palette?  You can change the scales easily enough to be a -1 to +1.

You can certainly use a gage or meter to display the values that you state. What specifically is your problem? How often do you get a new value?

I have exactly the same problem. How to do it? If you create a scale with a minimum and a maximum value of -0.5 + 0.5, in the center of the scale is 0 instead of 1 as it should be...

The center of the range -0.5 to +0.5 IS zero. I don't know why you think differently.

I think he wants to make a LabVIEW version of the real-life meter seen here:

I don't know how you'd do that with any sort of standard control, though...

I would like to use meter with scale as show in post #1 . That's why I would like to see in the center 1 NOT 0

It should look something like this. I used a text label for scale markers.

text labes    Value

-0.5                0

-0.6                1

-0.7                2

-0.8                3

-0.9                4

1                    5

0.9                 6

0.8                 7

0.7                 8

0.6                 9

0.5                 10

But how to convert  1 +/- 0.5  -->>  0 to 10 I don't know...

Solved. Thanks to everyone
