           Summary: Matrix can not be updated automatically after changing
                    its source Data range
           Product: kst
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kst kde org
        ReportedBy: yiwenv live ca


Version:           1.6.0 (using KDE 4.0.0)
Installed from:    Compiled From Sources
OS:                Linux

Problem:
After specifying data range for an existing matrix in Data Manager, the matrix will not be updated automatically until some other operation has been done, such as generating another vector,etc. 
 
Example:
Open kst, construct a matrix from a data source called mx.dat in attached file.
Data-->New Matrix... --> select the file name: mx.dat and field [MATRIX,5,0,0,1,1]
A new matrix [MATRIX,5,0,0,1,1] with 10 samples is shown in data manager.

Right Click on this matrix and choose Edit... 
Uncheck Read to end options for X/Ynumber of fames,
 and change X number of frame = 2 and Y number of frames =2

Now, in Data Manager, the sample number of the matrix is still 10, but it should be 4.

Select View Matrix Values... in Data menu, the matrix entries are not updated.

However, if you do another operation at this time, such as generating a new static vector from Data Manager. The matrix [MATRIX,5,0,0,1,1] will be updated in both Data Manager and View Matrix Value.
