How to plot a complicated 3D graph

Asked by John
on 11 Jan 2012

Hi there,

I'm only new to matlab but I'm trying to plot a graph like this

I would appreciate any feedback, suggestions, advice on how you could achieve this

I have an array of arrival times and departure times.

x=load('arrivaltimes.txt'); y=load('departuretimes.txt');

Would I start off by plotting a histogram of departure times and arrival times. Then a scatter plot of arrival and departure times. And then some how make them 3D?

Thank you

hist() calls bar() to create the plots. bar() creates a hggroup object whose children are patch objects, each of which has XData and YData properties defining where the patch should be drawn. Each of those patches will also have an empty ZData property.

You can play tricks such as grabbing the YData, setting the ZData to that, and setting the YData to an array of constant value.

For the scatter plot, use scatter3()
