Inheritance diagram for bridges::datastructure::LineChart:

Detailed Description

Show series of data or functions using a line chart.

Line charts (https://en.wikipedia.org/wiki/Line_chart) are used to represent graphically functions such as f(x) = 3*x+1, or data such as temperature of a liquid on a stove as time passes. A individual function or a set of data is called "series".

A series is represented by two arrays xdata and ydata such that there is a point at (xdata[0], ydata[0]), an other at (xdata[1], ydata[1]), ... One can add a series by passing the two arrays using setDataSeries() or add the arrays individually using setXData() and setYData().

The different series have a label associated with them by default which can be disabled (see toggleSeriesLabel()).

The data is typically shown with axes that use a linear scale. However, the scale can be changed to logarithmic for each axis individually (see toggleLogarithmicX() and toggleLogarithmic()).

The LineChart can have a title (see getTitle() and setTitle()) and a subtitle (see setSubTitle() and getSubTitle()).

		vector< double >	ydata
	)

inline

Add a series (or update it)

Parameters

seriesName	indicates the series to add (or change)
xdata	the X data in the series
ydata	the Y data in the series

◆ setSubTitle()

void bridges::datastructure::LineChart::setSubTitle ( string s )

inline

Subtitle of the plot.

Parameters

s	the subtitle to be shown

◆ setTitle()

void bridges::datastructure::LineChart::setTitle ( string t )

inline

Parameters

t	the title to be shown

◆ setXData()

void bridges::datastructure::LineChart::setXData	(	string	series,
		vector< double >	xdata
	)

inline

Changes the X data for a series.

Parameters

series	indicates the series to get
xdata	the X data in the series

◆ setXLabel()

void bridges::datastructure::LineChart::setXLabel ( string xaxisName )

inline

Change the label for the X-axis.

Parameters

xaxisName label to use for the X-axis

◆ setYData()

void bridges::datastructure::LineChart::setYData	(	string	series,
		vector< double >	ydata
	)

inline

Parameters

series	indicates the series to get
ydata	the Y data in the series

◆ setYLabel()

void bridges::datastructure::LineChart::setYLabel ( string yaxisName )

inline

Change the label for the Y-axis.

Parameters

yaxisName label to show for the Y-axis

◆ toggleLogarithmicX()

void bridges::datastructure::LineChart::toggleLogarithmicX ( bool val )

inline

Change the X-axis scale to logarithmic.

When enabled, the X-axis scale becomes logarithmic (as opposed to linear).

Parameters

val	Should the X-axis use a logarithmic scale?

◆ toggleLogarithmicY()

void bridges::datastructure::LineChart::toggleLogarithmicY ( bool val )

inline

Change the Y-axis scale to logarithmic.

When enabled, the Y-axis scale becomes logarithmic (as opposed to linear).

Parameters

val	Should the Y-axis use a logarithmic scale?

◆ toggleMouseTrack()

void bridges::datastructure::LineChart::toggleMouseTrack ( bool val )

inline

Enables or disables mouse tracking.

Mouse tracking show the value of a data point when the mouse hovers on a data point.

Parameters

val	Should mouse tracking be activated or not.

◆ toggleSeriesLabel()

void bridges::datastructure::LineChart::toggleSeriesLabel ( bool val )

inline

Enables or disables series labels.

When enabled, the name of the series will be shown on the line chart.

Parameters

val	Should series be labeled or not
