Fancy DualGraphs

Create double axis to use with matlab plotting tools, and automatically draw markers.

Most dual axis functions take the data to be plot as arguments, thus, losing the flexibility given by existing plotting functions. Moreover, they are not suited for Black/White printing.

Fancy DualGraphs separates the dual-axis feature, from plotting, so you can keep using your plotting tools and options, but in a dual axis fashion. Moreover, it has the option of adding elliptical markers onto data, pointing to the proper axis. This improves the readibility, mainly in B/W prints.

The horizontal position of the markers, as well as their size, are configurable in a simple and documented fashion.

The code of the screenshot is as simple as follows

[ax] = dualCreate();

% Left axis
plot(ax(1), x, y1)
ylabel(ax(1),'Output 1')

% Right axis
plot(ax(2), x, y2,'g')
hold(ax(2), 'on')
plot(ax(2), x, y3,'r')

ylabel(ax(2),'Output 2')
grid(ax(2),'on')

% Figure parameters
xlabel('Input')
title('Tile')
legend('Line 1','Line 2','Line 3')

% Finalize graph
dualFinalize(ax, [0.2 0.8], 0.1,[1 -1]);

% Some makeup
fancyGraph(gcf)
