Matlab 3D bar plot

Hi,

This is basic but could not find the solution. I wanted to plot a 3D Bar graph on MATLAB of the following array:

X Y Z

6.50319529000000 10 5

6.50463629000000 10 10

6.50548840000000 10 15

6.50607061000000 10 20

6.26503134000000 12 5

6.26630878000000 12 10

6.26717043000000 12 15

6.26777792000000 12 20

6.01515388000000 14 5

6.01623726000000 14 10

6.01715994000000 14 15

6.01779366000000 14 20

5.74271154000000 16 5

5.74320126000000 16 10

5.74414110000000 16 15

5.74482298000000 16 20

Can someone help me with this?

Thank you so much! This was really helpful.

However, now if I want to plot the x axis values on the z axis with axis values in 0.1(5.6 to 6.6) increments. How do I go about it?

See above.

I got it! Thank you so much!

Use zlim:

zlim([4 6])         % adjust value
