Image_Graph_Axis_Logarithmic (Constructor) [line 62]

Image_Graph_Axis_Logarithmic Image_Graph_Axis_Logarithmic(
[int
$type = IMAGE_GRAPH_AXIS_X])

Image_Graph_AxisLogarithmic [Constructor].

Normally a manual creation should not be necessary, axis are created automatically by the Image_Graph_Plotarea constructor unless explicitly defined otherwise

Parameters:

int $type — The type (direction) of the Axis, use IMAGE_GRAPH_AXIS_X for an X-axis (default, may be omitted) and IMAGE_GRAPH_AXIS_Y for Y- axis)

[ Top ]

forceMinimum [line 90]

void forceMinimum(
double
$minimum)

Forces the minimum value of the axis.

For an logarithimc axis this is always 0

Overrides Image_Graph_Axis::forceMinimum() (Forces the minimum value of the axis)

Parameters:

double $minimum — The minumum value to use on the axis
