bridges.line_chart.LineChart Class Reference

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()).
