Scale of the angle.

Definition at line 114 of file basicgraph.h.
References getYScale().

bool BasicGraph::getAxisState ( ) const [inline, virtual]

Returns :
Scale of the radius.

Definition at line 111 of file basicgraph.h.
References getXScale().

bool BasicGraph::getScaleState ( ) const [inline, virtual]

Returns :
Whether of not the labeling of the scale is turned on.

Implements CommonGraph.
Definition at line 123 of file basicgraph.h.

double BasicGraph::getXMax ( ) const [inline]

Returns :
Maximum x bounds

Definition at line 96 of file basicgraph.h.

double BasicGraph::getXMin ( ) const [inline]

Returns :
Minimum x bounds

Definition at line 93 of file basicgraph.h.

double BasicGraph::getXScale ( ) const [inline]

Returns :
Scale on the x direction.

Definition at line 105 of file basicgraph.h.
Referenced by getRScale().

int BasicGraph::getXZoomFactor ( ) const [virtual]

Returns :
Factor of zoom in the x direction which is used in a call to zoomIn() or zoomOut().

Implements CommonGraph.
Definition at line 607 of file basicgraph.cpp.

double BasicGraph::getYMax ( ) const [inline]

Returns :
Maximum x bounds

Definition at line 102 of file basicgraph.h.

double BasicGraph::getYMin ( ) const [inline]

Returns :

Definition at line 612 of file basicgraph.cpp.

QColor BasicGraph::gridColor ( ) const [virtual]

Returns :
Color of the grid.

Implements CommonGraph.
Definition at line 592 of file basicgraph.cpp.

void BasicGraph::installMathFunctions ( ) [virtual]

Implement this function to install any MathFunction's to a specific class.
A math function should be added by calling addMathFunction( MathFunction*, const char * id ) Example: addMathFunction(new DistanceMathFunction(this), "Distance");
Reimplemented from MathFunctionImplementor.
Reimplemented in FunctionGraph, and ParametricGraph.
Definition at line 733 of file basicgraph.cpp.
References MathFunctionImplementor::addMathFunction().
Referenced by ParametricGraph::installMathFunctions(), and FunctionGraph::installMathFunctions().

void BasicGraph::offscreenResize ( int width,

int height

)

Resizes the on- and off-screen buffer of the graph.
Call this, as opposed to resize(), when the graph needs to be resized, but is not currently shown. This essentially forces a resizeEvent(), as a resizeEvent() will not be called when the graph is not visible.
Definition at line 321 of file basicgraph.cpp.

void BasicGraph::print ( QPrinter * ) [virtual]

Prints graph as is.
A printer setup dialog will be opened.
Implements CommonGraph.
Reimplemented in ExpressionGraph, and StatPlotGraph.
Definition at line 661 of file basicgraph.cpp.

QColor BasicGraph::scaleColor ( ) const [virtual]

Returns :
Color of the scale.

Implements CommonGraph.
Definition at line 602 of file basicgraph.cpp.

void BasicGraph::setMouseX ( double x_coordiniate,

bool snapToGrid = true

) [protected]

Sets the x-coordinate at which you wish the graph to think the mouse is at to the value in "x_coordinate".
The second argument can optionally be given and this is a boolean which overrides the global option of whether or not to snap to the grid.
Definition at line 683 of file basicgraph.cpp.

void BasicGraph::setMouseY ( double y_coordiniate,

bool snapToGrid = true

) [protected]

Sets the y-coordinate at which you wish the graph to think the mouse is at to the value in "y_coordinate".
The second argument can optionally be given and this is a boolean which overrides whether the global option to snap to the grid.
Definition at line 708 of file basicgraph.cpp.

int BasicGraph::setRange ( double xMin,

double xMax,

double yMin,

double yMax

)

Sets the x and y minimum and maximum bounds all in one call.
This is equivalent to calling each seperate setXMin, setXMax, etc. function except calling this function will only update the graph once.
Definition at line 441 of file basicgraph.cpp.

int BasicGraph::setXScale ( double xScale )

Sets the scale on the x direction.
This is the distance that the grid is spaced in the x direction and the spacing of the x scale.
Definition at line 480 of file basicgraph.cpp.

int BasicGraph::setYScale ( double yScale )

Sets the scale on the x direction.
This is the distance that the grid is spaced in the x direction and the spacing of the x scale.
