Classe: Image_Graph_Plotarea - X-Ref
Plot area used for drawing plots.| Image_Graph_Plotarea($axisX = 'Image_Graph_Axis_Category', $axisY = 'Image_Graph_Axis', $direction = 'vertical') X-Ref |
| Image_Graph_Plotarea [Constructor] param: string $axisX The class of the X axis (if omitted a std. axis is created) param: string $axisY The class of the Y axis (if omitted a std. axis is created) param: string $direction The direction of the plotarea - 'horizontal' or 'vertical' (default) |
| _setParent(& $parent) X-Ref |
| Sets the parent. The parent chain should ultimately be a GraPHP object param: Image_Graph_Common $parent The parent |
| setPlotBorderStyle(& $plotBorderStyle) X-Ref |
| Sets the plot border line style of the element. param: Image_Graph_Line $lineStyle The line style of the border |
| add(& $element, $axis = IMAGE_GRAPH_AXIS_Y) X-Ref |
| Adds an element to the plotarea param: Image_Graph_Element $element The element to add param: int $axis The axis to associate the element with, either return: Image_Graph_Element The added element |
| _plotWidth() X-Ref |
| Get the width of the 'real' plotarea return: int The width of the 'real' plotarea, ie not including space occupied by padding and axis |
| _plotHeight() X-Ref |
| Get the height of the 'real' plotarea return: int The height of the 'real' plotarea, ie not including space |
| _setExtrema(& $plot) X-Ref |
| Set the extrema of the axis param: Image_Graph_Plot $plot The plot that 'hold' the values |
| _fillLeft() X-Ref |
| Left boundary of the background fill area return: int Leftmost position on the canvas |
| _fillTop() X-Ref |
| Top boundary of the background fill area return: int Topmost position on the canvas |
| _fillRight() X-Ref |
| Right boundary of the background fill area return: int Rightmost position on the canvas |
| _fillBottom() X-Ref |
| Bottom boundary of the background fill area return: int Bottommost position on the canvas |
| _axisPointX($value, $min, $max) X-Ref |
| Get the point from the x-axis param: array $value The value array param: int $min The minimum pixel position possible param: int $max The maximum pixel position possible return: int The pixel position from the axis |
| _axisPointY($value, $min, $max) X-Ref |
| Get the point from the x-axis param: array $value The value array param: int $min The minimum pixel position possible param: int $max The maximum pixel position possible return: int The pixel position from the axis |
| _pointX($value) X-Ref |
| Get the X pixel position represented by a value param: double Value the value to get the pixel-point for return: double The pixel position along the axis |
| _pointY($value) X-Ref |
| Get the Y pixel position represented by a value param: double Value the value to get the pixel-point for return: double The pixel position along the axis |
| _getMinimum($axis = IMAGE_GRAPH_AXIS_Y) X-Ref |
| Return the minimum value of the specified axis param: int $axis The axis to return the minimum value of (see {$link return: double The minimum value of the axis |
| _getMaximum($axis = IMAGE_GRAPH_AXIS_Y) X-Ref |
| Return the maximum value of the specified axis param: int $axis The axis to return the maximum value of(see {$link return: double The maximum value of the axis |
| _labelDistance($axis) X-Ref |
| Return the label distance for the specified axis. param: int $axis The axis to return the label distance for return: int The distance between 2 adjacent labels |
| hideAxis($axis = false) X-Ref |
| Hides the axis |
| clearAxis() X-Ref |
| Clears/removes the axis |
| getAxis($axis = IMAGE_GRAPH_AXIS_X) X-Ref |
| Get axis. Possible values are IMAGE_GRAPH_AXIS_X, IMAGE_GRAPH_AXIS_Y, IMAGE_GRAPH_AXIS_Y_SECONDARY or a short hand notation using string identifiers: 'x', 'y', 'ysec' param: int $axis The axis to return return: Image_Graph_Axis The axis |
| _updateCoords() X-Ref |
| Update coordinates |
| setAxisPadding($value, $position = false) X-Ref |
| Set the axis padding for a specified position. The axis padding is padding "inside" the plotarea (i.e. to put some space between the axis line and the actual plot). This can be specified in a number of ways: 1) Specify an associated array with 'left', 'top', 'right' and 'bottom' indices with values for the paddings. Leave out 2nd parameter. 2) Specify an overall padding as the first parameter 3) Specify the padding and position with position values as mentioned above Normally you'd only consider applying axis padding to a category x-axis. param: mixed $value The value/padding param: mixed $position The "position" of the padding |
| _done() X-Ref |
| Output the plotarea to the canvas return: bool Was the output 'good' (true) or 'bad' (false). |
