How can I plot a 3D Histogram with one axis of categorical data?

Hi I'm trying to create a 3D histogram using hist3 and would like the following axes:

1. x-axis: categorical data eg. the type of modification to the set-up
2. y-axis: output data eg. time
3. z-axis: frequency.

I understand how to get the y and z axis conditions, but I am unsure of how to get categorical data on one of the axes in a 3d plot.

Hi Aseer,

For the hist3 function the user should need a 2D Matrix in which 1st column is x value, and 2nd column is y value. Then the function plots number of occurrences of the pairs x, y as the z parameter.

The 2D matrix has to be numeric in data in this function, for this you have to convert categories into numeric data.
