suppose i have,

x=50 100 150 200;

y=200 400 600 800;

z=5 10 15 20;

how can i plot these values?

You don't have gridded data, so to plot just those points I'd use plot3.

If you have the variables you want to plot selected in the Workspace browser you can open the Plots tab on the toolstrip to see some of the available plotting functions that can accept the selected data. If you click on the thumbnail MATLAB will create the selected plot.

As @Steven Lord mentions, you don't have gridded data, thus you won't be able to plot a surface with the given data, just a line.

Hi Asif,

As per my understanding, you want to plot 3D graphs in MATLAB.

Similar to plotting 2D graphs, where we use plot(), scatter(), bar(), etc., we use plot3(), scatter3(), bar3(), etc. functions to plot 3D graphs in MATLAB.

Whereas to plot the surface plots which you have mentioned in the question, we use surf() function.

For further reference, please refer these links to know more about ‘plot3’, ‘surf’ functions.

I hope this helps resolving the issue.
