How to plot power factor as a graph?

[GerdW]

Hi EduU,

if you really want this then look at my example from the other thread!

If the example isn't clear enough then ask in that thread for more information...

I was looking here GerdW, this give me like 1 power factor... I need plot the 3 in the same graph....

so I repeat your code 3 times... so I only have to plot that?

or I need to change something more?

[EduU]

more one thing GerdW, how can I put two scales on Y-axis ??

I didn't find where I have to change for that =x

[GerdW]

Hi EduU,

to create a new Y-scale you right-click the current Y-scale and select "duplicate...".

"I was looking here GerdW, this give me like 1 power factor... I need plot the 3 in the same graph.... so I repeat your code 3 times... so I only have to plot that? or I need to change something more?"

I really don't understand what you're saying here... If you want to plot more than one line in the graph you should build an array of plots like shown in the context help of the graph...

Ok it's done!

Now I will test here and see if it works!

THanks

Well I made it with 1 line, and it works....

but I need a help in one thing, if the user want to zoom the graph... to see a value with more precision... the scale wont change.... so how can I make that?

[EduU]

More one thing that I need help, I have the rms numbers of voltage, current, real power, apparent power and reacitive power.... How can I calculate the power factor without analysing the waveforms to know the angle? because I have the correct values but sometimes the real is capacitive and I get values inductive...

So I have to find a way to calculate power factor capacitive and inductive with the RMS numbers 😞

any help on that?
