FITTING IN XY GRAPH

[DODI]

Hello

I am new to LabVIEW and have problems fitting curves in xy graph.

I can fit in waveform graph, but not in XY graph.

Here is my program.

Thank you for your answers.

Hi Dodi,

you don't have problems with fittings but with graphical representation.

Both graphs show the same data - but in different "style"/"interpretation". The waveform graph shows both "plots" vs. the index of the plot items. The XY graph shows them "plot1" vs "plot2"...

You are right. I made it .

Thank you for your clue.

I also posted one question about FIR filter. Do you happen to know

how to add taps as control in FIR filter?

Hi Dodi,

your VI doesn't contain any FIR filter stuff!?

[DODI]

I have usual FIR filter which has Lower cut off frequency control. But

it does not have taps control. Is it possible to make taps control to it or to select other block with same properties as this FILTER block?

Thank you for your answers.

Hi Dodi,

have you read the help? Maybe this? Or looked at the FIR filter function palette?

Lesson learned should be: Never trust on ExpressVIs, when you need some special or uncommon functionalities...
