Detailed Description
A class to render an axis graduated with numerical values for a given
range.
This class allows to draw a quantitative axis (i.e. an axis axis
graduated with numerical values for a given range)
Constructor & Destructor Documentation
tlp::GlQuantitativeAxis::GlQuantitativeAxis (const std::string & axisName,
const Coord & axisBaseCoord, const float axisLength, const
AxisOrientation & axisOrientation, const Color & axisColor, const bool
addArrow = true, const bool ascendingOrder = true) GlQuantitativeAxis
constructor. Create an quantitative axis without graduations (need to
call setAxisParameters to build them)
Parameters:
axisName the name of the axis the base coord of the axis (if the
axis is horizontal, it is the the left end, if vertical it is the
down end) the length of the axis the orientation of the axis, 2
possible values (HORIZONTAL_AXIS or VERTICAL_AXIS) the color of
the axis If true, an arrow will be added to one end of the axis
according to the axis order (ascending or descending) If true, the
min value will be at the bottom end and the max will be at the top
end if the axis is vertical (min at the left and max at the right
if it is horizontal). If false this positions are switched
Member Function Documentation
Coord tlp::GlQuantitativeAxis::getAxisPointCoordForValue (double value)
const Method to get the axis point coordinates for a given value
Parameters:
value the value we want to retrieve axis point coordinates
double tlp::GlQuantitativeAxis::getValueForAxisPoint (const Coord &
axisPointCoord) Method to get the value associated to an axis point
Parameters:
axisPointCoord the axis point coordinates we want to retrieve
associated value
bool tlp::GlQuantitativeAxis::hasAscendingOrder () const [inline] Method to
get the order of the values on the axis (ascending or descending)
void tlp::GlQuantitativeAxis::setAscendingOrder (const bool ascendingOrder)
[inline] Method to set the order of the values on the axis (ascending
or descending). A call to updateAxis has to be done after calling this
method to build or update the axis graduations
void tlp::GlQuantitativeAxis::setAxisParameters (const int min, const int
max, const unsigned int incrementStep, const LabelPosition &
axisGradsLabelsPosition = LEFT_OR_BELOW, const bool drawFirstLabel =
true)
void tlp::GlQuantitativeAxis::setAxisParameters (const double min, const
double max, const unsigned int nbGraduations, const LabelPosition &
axisGradsLabelsPosition = LEFT_OR_BELOW, const bool drawFirstLabel =
true) Method to set the quantitative axis parameters. A call to
updateAxis has to be done after calling this method to build or update
the axis graduations
Parameters:
min the min value of the range the axis represents
max the max value of the range the axis represents
nbGraduations the number of graduations to build
axisGradsLabelsPosition the relative position of the axis
graduations label. Two possible values : LEFT_OR_BELOW (if the axis
is vertical, labels will be on the left of the axis, otherwise
below) or RIGHT_OR_ABOVE
drawFirstLabel If false, the first graduation label will not be
drawn (usefull when some axis have the same base coord to avoid
labels overlapping)
void tlp::GlQuantitativeAxis::setLogScale (const bool logScale, const
unsigned int logBase = 10) Method to set a logarithmic scale on the
axis. A call to updateAxis has to be done after calling this method to
build or update the axis graduations
Parameters:
logScale If true, activate the logarithmic scale on the axis
logBase If filled, set the logarithm base
void tlp::GlQuantitativeAxis::updateAxis () [virtual] Method to update the
axis drawing. It has to be called when one (or more) of the setters
method above has been used. This method redraw the whole axis and the
graduations.
Reimplemented from tlp::GlAxis.
