Plotting a 3-D line plot with user defined axis.

I have the x, y and z coordinates of a particle at different times in a matrix and I plotted them on a graph

plot3(point(:,1),point(:,2),point(:,3))

However, I need the x and z axis to switch positions i.e. the x axis should be the vertical one while the z axis the right hand axis. Is there a way to write a code to do this? The above code is in an m-file and I want to add that option to the file.

swapAxis = true; % modify to suit
if(swapAxis)
    plot3(point(:,3),point(:,2),point(:,1))
else
    plot3(point(:,1),point(:,2),point(:,3))
end

Do I misunderstand?

Hi,
The code didn't work. I need the x values to plot along the vertical axis. The code didn't change anything.
