Image_Graph_Plot_Smoothed_Bezier:: (5 méthodes):
  Image_Graph_Plot_Smoothed_Bezier()
  _minimumY()
  _maximumY()
  _getControlPoints()
  _addSamplePoints()

Classe: Image_Graph_Plot_Smoothed_Bezier - X-Ref

Bezier smoothed plottype.

The framework for calculating the Bezier smoothed curve from the dataset.
Used in {@link Image_Graph_Plot_Smoothed_Line} and {@link
Image_Graph_Plot_Smoothed_Area}. Smoothed charts are only supported with non-
stacked types

Image_Graph_Plot_Smoothed_Bezier(& $dataset, $title = '') X-Ref

Image_Graph_Plot_Smoothed_Bezier [Constructor]

Only 'normal' multitype supported

param: Dataset $dataset The data set (value containter) to plot
param: string $title The title of the plot (used for legends, {@link

_minimumY() X-Ref

Return the minimum Y point

return: double The minumum Y point

_maximumY() X-Ref

Return the maximum Y point

return: double The maximum Y point

_getControlPoints($p1, $p0, $p2, $p3) X-Ref

Calculates all Bezier points, for the curve

param: array $p1 The actual point to calculate control points for
param: array $p0 The point "just before" $p1
param: array $p2 The point "just after" $p1
param: array $p3 The point "just after" $p2
return: array Array of Bezier points

_addSamplePoints($x0, $y0, $x1, $y1) X-Ref

Create legend sample data for the canvas.

Common for all smoothed plots
