signalsmith::plot::Axis Class Reference

#include <plot.h>

Detailed Description

A map from values to screen-space.

Individual grid/ticks can be added with .major()/.minor()/.tick().

axis.major(4); // default label
axis.major(5, "five"); // explicit label

Multiple grids/ticks can be added using .majors()/.minors()/.ticks(), which accept a variable number of values:

axis.majors(0, 10).minors(2, 4, 6, 8);

Method Details

autoValue()

void signalsmith::plot::Axis::autoValue ( double v )

inline

Register a value for the auto-scale.

blank()

Axis & signalsmith::plot::Axis::blank ( bool includeLinked = false )

inline

Prevent auto-labelling.

blankLabels()

Axis & signalsmith::plot::Axis::blankLabels ( bool includeLinked = false )

inline

Clear the names from any existing labels.

copyFrom()

Axis & signalsmith::plot::Axis::copyFrom ( Axis & other, bool clearLabels = false )

inline

Copy ticks/label from another axis, optionally removing their text.

label()

Axis & signalsmith::plot::Axis::label ( std::string l, PlotStyle::Counter index = -1 )

inline

Sets the label, and optionally style to match a particular line.

linkFrom()

Axis & signalsmith::plot::Axis::linkFrom ( Axis & other )

inline

Link this axis to another, copying any ticks/labels set later as well.

Member Data Documentation

flipped

bool signalsmith::plot::Axis::flipped = false

Whether the axis should draw on the non-default side (e.g. right/top)

styleIndex

PlotStyle::Counter signalsmith::plot::Axis::styleIndex = -1

Not associated with a particular line by default, but can be.
