# tlp::GlNominativeAxis Class Reference `#include <GlNominativeAxis.h>` Inherits tlp::GlAxis. Inheritance diagram for tlp::GlNominativeAxis: [legend] Collaboration diagram for tlp::GlNominativeAxis: [legend] List of all members. ## Detailed Description A class to render an axis graduated with string values. This class allow to draw a nominative axis (i.e. an axis graduated with string values) ## Public Member Functions GlNominativeAxis (const std::string &axisName, const Coord &axisBaseCoord, const float axisLength, const AxisOrientation &axisOrientation, const Color &axisColor) void setAxisGraduationsLabels (const std::vector< std::string > &axisGradsLabels, const LabelPosition &labelsPosition) void updateAxis () Coord getAxisPointCoordForValue (std::string value) std::string getValueAtAxisPoint (const Coord &axisPointCoord) void translate (const Coord &c) ## Constructor & Destructor Documentation
tlp::GlNominativeAxis::GlNominativeAxis | ( | const std::string & | axisName,
|  | const Coord & | axisBaseCoord,
|  | const float | axisLength,
|  | const AxisOrientation & | axisOrientation,
|  | const Color & | axisColor
| ) |
  | GlNominativeAxis constructor. Build a nominative axis with no graduations (need to call setAxisGraduationsLabels 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
## Member Function Documentation
Coord tlp::GlNominativeAxis::getAxisPointCoordForValue | ( | std::string | value | ) |
  | Method to get the axis point coordinates associated to string value Parameters:
  | value | the string value we want to retrieve axis point coordinates
std::string tlp::GlNominativeAxis::getValueAtAxisPoint | ( | const Coord & | axisPointCoord | ) |
  | Method to get the string value associated to an axis point. Return "" if there is not. Parameters:
  | axisPointCoord | the axis point coordinates we want to retrieve the associated string value
void tlp::GlNominativeAxis::setAxisGraduationsLabels | ( | const std::vector< std::string > & | axisGradsLabels,
|  | const LabelPosition & | labelsPosition
| ) |
  | Method to set the axis graduations labels. A call to updateAxis has to be done after calling this method to build or update the axis graduations. The labels will be placed on the axis in the same order as the vector passed as parameter (from bottom to top if the axis is vertical, from left to right if it is horizontal). Parameters:
  | axisGradsLabels | a vector of string containing the graduations labels
  | labelsPosition | 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
void tlp::GlNominativeAxis::translate | ( | const Coord & | c | ) | `[virtual]`
| translate the composite with children Reimplemented from tlp::GlAxis.
void tlp::GlNominativeAxis::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.
