Line Chart Tutorial

BRIDGES provides a basic set of line charts (https://en.wikipedia.org/wiki/Line_chart) for plotting single or multiple functions; its most often useful in benchmarking algorithms.

Individual functions are represented by pairs of arrays, say 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()).

This tutorial will illustrate the use of line charts to draw functions in both linear and logarithmic scale.
