LineGraph

Linegraphs are most commonly used to represent data which changes over time (stock prices or currency values are typical) but may be used wherever pairs of X and Y values are joined by lines. The default is to join the points with straight lines, but for some applications (for example illustrating a graph of Y-squared versus X) then it is better to use smooth curves.

This chart has a wide variety of styles, for example it can draw risers from the X-axis, fill the surface, add arrowheads to the end of each line, and so on. These styles can be combined as required by calling DrawLineGraph several times with different style settings to overlay multiple charts on the same set of axes.

SharpPlot sp = new SharpPlot;
sp.SetMargins(12,12,18,4);
sp.LineGraphStyle = LineGraphStyles.Risers;
data = new int[] {18,27,31,12,19,23};
sp.DrawLineGraph(data);
