Find 6 Data points from Signal line displayed is Graphs-Any Maths idea..Please assist

[Dskp]

Hi,

I came across a project in LabVIEW to detected some 6 data points value as shown in the attached screen shot.

These 6 data points makes a cycle and this continues to get the 6 data points for all cycles till plot data ends.

Any mathematical idea  would be appreciated for getting this done in LabVIEW.

Hello dskp,

As your in Cartesian display, if you know the abscissa or the ordinate, you could easily found your points using a for loop with your data points indexed in input and a comparison function.

Please be more specific if you need an example.

Best regards.

Hi dspk,

use the first derivative (aka slope) to determine your points.

Point5 might be tricky to detect: how do you define it?
