```
    Gets the index in data with given pixel position in the graphic. The wrapping index in the data is contained in ixDataShown.

  - selectTrack
```
protected boolean selectTrack(int xpos,
                              int ypos,
                              int xsize,
                              int ysize)
```
    Determines and switches a curve to select by mouse click. The curve should be at least 10 pixel near the mouse position.
    Algorithm: From mouse position the index in the data are calculated: getIxDataFromPixelRight(int). Any track is checked: The value (float) is read, the scaling is used to calculate the y-Position. Then the distance between mouse and track is calculated.
    
    Parameters:
    
    xpos - Mouse position on click in pixel
    
    ypos -
    
    xsize - size of the curve view widget.
    
    ysize -
    
    Returns:
    
    true if a track is selected. false if the position is more as 10 pixels far of any track.
  - setCursors
```
protected void setCursors(int xPos)
```
  - moveCursor
```
protected void moveCursor(int xMousePixel)
```
  - zoomToPresent
```
protected void zoomToPresent()
```
    Zooms the curve presentation with same index right with a lesser time spread. If the curve presentation is running yet, a finer solution in the present is given. Note that in this case the right index is the actual write index.
  - zoomToPast
```
protected void zoomToPast()
```
    Zooms the curve presentation with same index right with a greater time spread. If the curve presentation is running yet, a broader solution in the present is given. Note that in this case the right index is the actual write index.
  - zoomBetweenCursors
```
protected void zoomBetweenCursors()
```
    Zooms between the given vertical cursors. The time spread is calculated so that the cursors are places on the same data indices at 1/10 and 9/10 of the presentation range.
  - cursorUnzoom
```
protected void cursorUnzoom()
```
    Unzooms between the given vertical cursors. The cursors will be set newly in graphic at the same data indices. The middle value of both cursors will be at the same position. The time spread is multiplied by the value 5. If the right border of presentation will be in the future, the ixDataShowRight will be greater than GralCurveView.ixDataWr, then the presentation will be adjusted to the current right GralCurveView.ixDataWr and the cursor positions are changed adequate.
  - viewToPresentOrGoIrRefresh
```
protected void viewToPresentOrGoIrRefresh()
```
    Shifts the curve presentation to the present (actual values). If the TODO
  - stopAndViewToPast
```
protected void stopAndViewToPast()
```
    Shifts the curve presentation to the past. If the presentation is running, it is stopped firstly. If it is stopped, the data index on 20% of current presentation will be adjusted to the right border. It means 20% are presented overlapping. The time spread is not changed.
  - mouseSelectCursur
```
protected void mouseSelectCursur(int xMousePixel,
                                 int yMousePixel)
```
  - prepareIndicesDataForDrawing
```
protected int prepareIndicesDataForDrawing(int ixDataRight,
                                           int xViewPart,
                                           int timePart,
                                           boolean bPaintAll)
```
    prepares indices of data. All data have a timestamp. the xpixel-values are calculated from the timestamp. The ixDataShown array will be filled with the indices to the data for each x pixel from right to left. If there are more as one data record for one pixel, the step width of ixData is >1, If there are more as one x-pixel for one data record, the same index is written for that pixel
    
    It uses the timeValues to get the timestamp of the values starting from param ixDataRight for the right pixel of view. The ixDataRight will be decremented. It is a wrapping index with step width of GralCurveView.adIxData. If the timestamp of any next index is greater than the last one, it is a indication that any newer data are reached after wrapping. Then the preparation stops.
    
    It fills ixDataShown with indices to data per x pixel point. If there are the same data for more as one pixel (zoomed near), then ixDataShown will contain the same index. The presentation can decide whether it should be shown with the same level (stepwise) or with any linear approximation
    
    Parameters:
    
    ixDataRight - Index in data array for the right point. It is a index which wraps around full integer range, see GralCurveView.adIxData.
    
    xViewPart - width of the spread to prepare in pixel
    
    Returns:
    
    nrof pixel to draw. It is xViewPart if enough data are available, elsewhere less. TODO move to ImplAccess
