Teechart drawing how to get to point coordinate values-CodePudding

Vs2013 + teechart5
Use teechart drew a line chart, now want to get the picture several peaks corresponding to the abscissa put into the array is used to calculate next, excuse me how to get under the bosses can help?

This has nothing to do with teechart? Data is you fill in, you can make up a simple function of statistical all the extremum,

What statistical extreme value? I will only ask the maximum and the minimum of the whole, don't know how to find each wave

CodePudding user response:

The slope and the local maximum???

The most simple algorithm, the if (y [I - 1] <[I] y & amp; & Y [I + 1] Also is looking for a local maximum, may not be very perfect,

Can I still want to select from figure because some error obviously wrong points I can out,,

Emmm the push_back (I); Why use, checked the seems to be in the list of the added element used for?

Ao I seemed to understand, is I create a new peak and the peak one add meh? Can like hey I give it a try!
But with the experimental data with error so I actually prefer to look at the picture, and then out looks error is too large, so tend teechart draw and then find some
