[RESOLVED] Copying a chart series to another

[pourkascheff]

Consider you have an array of charts, filled with one series of x,y points and you want to clone a specific one in another large chart (in another form) to perform a sort of magnification operation for selected member of that array.

What is the proper approach to achieve such thing?

How about a for loop to add points from here to another?

For i=0 to Me.Chart1.Series(0).Points.All then
            Form2.Chart1.Series(0).add = Me.Chart1.Series(0).Points(i)
        Next

Codes are wrong. Only for understanding

Or is there a property/method thing to shortcut looping?

Form2.Chart1 = Me.Chart1

Codes are wrong. Only for understanding

Don't know either ways. I just assumed they're possible ways.
Thanks in advance/.

you have to do it the hard way : transfer the serie in a list

use a list of tuple or use a list of pointf or create a structure named Points (if you want to use double)

Hello again after a long absence, some lads here in another thread, asked for a same thing in 2011 but no results were also achieved.

Does chart control have a sort of conventional "datasource" thing to make it equal to another chart in one line code? The point is the latter one (Let's call it the follower) does not need to be real time as the one which are located next to lots of other charts. Only all xy points from the beginning to the moment you "enlarge" it by some sort of double click action.

"Eureka". That was easy and in a loop behavior as I mentioned in starting topic, but since I used to show things more complicated than they need to be, I wrote down the idea in DevExpress 3rd party controls:
Mother form code:

    Private Sub XtraForm1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        For i = 0 To 10 'SOME RANDOM POINTS IN MOTHER FORM
            ChartControlMain.Series(0).Points.AddPoint(i.ToString, Rnd())
        Next
    End Sub
    Private Sub ChartControlMain_Click(sender As Object, e As EventArgs) Handles ChartControlMain.Click
        Dim newform As New CHILDFORM
        For i = 0 To ChartControlMain.Series(0).Points.Count - 1
            newform.ChartControlEnlarge.Series(0).Points.Add(ChartControlMain.Series(0).Points(i))
        Next
        newform.ShowDialog()
    End Sub

case closed. peace/
