OCTAVE PLOT BAR3

How can I do this? Also I’ve used functions not available in Octave like membrane and spiral to build sample matrices, but those are not essential to the code, just replace them with your own data: Sign up using Email and Password. The function could have been implemented by specifying coordinates of connected vertices that form polygons, by using the XData , YData , ZData and CData properties instead of the Vertices and Faces properties. This is machine translation Translated by. Choose a web site to get translated content where available and see local events and offers. In fact this is what bar3 internally does.

Other MathWorks country sites are not optimized for visits from your location. This solution generates a surface in a similar way to the internals of Matlabs hist3d function. Each group contains one bar per column in Z. But why not incorporate the colouring bars by height as a C-data extra parameter to the function? One cool thing about that is you can very easily make much more funky-looking bars:. Have you looked at this tutorial on bar3? Or say you wanted to color the bars using gradient according to their heights:.

What is close to bar3?

Post as a guest Name. Amro Amro k 19 Below is a function I implemented that acts as a bar3 replacement partially. The automated translation of this page is provided by a general purpose third party translator tool.

Each bar is shifted and scaled according to kctave position and height. But why not incorporate the colouring bars by height as a C-data extra parameter to the function? MathWorks does not warrant, and disclaims all liability for, the accuracy, suitability, or fitness for purpose of the translation.

Have you looked at this tutorial on bar3? Each group contains one bar per column in Z. Hence the face [1 3 5] is a triangle connecting the first, third and fifth vertices.

Dan a face is a list of vertices, I suspect that octave does not support non-planar faces and therefore all faces here are triangles 3 vertices. Note that in the last example, bbar3 “Renderer” property of the figure will affect the appearance of the gradients.

Each is surrounded by zeros, which are also plotted at each bin edge. By default, the style is detached. Choose pllt web site to get translated content where available and see local events and offers.

Octave – General – What is close to bar3?

The function could have pllt implemented by specifying coordinates of connected vertices that form polygons, by using the XDataOtcaveZData and CData properties instead of the Vertices and Faces properties. Can you explain your faces matrix? I normally check here: I guess it could done, but bar3 which I tried to replicate doesn’t offer such syntax.

Load the data set count. I would suspect that if it doesn’t error then it does work though octaev I’m afraid I can’t really check. When Z is a vector, the y -axis scale ranges from 1 to length Z. One cool thing about that is you can very easily make much more funky-looking bars:. Great solution for Matlab – but it looks like bar3 doesn’t exist for Octave: When Z is a matrix, bar3 creates one Surface object per column in Z. Now you can call the function in of the following ways: Dan why have you added the matlab tag?

I think the following should do the trick.

Plot 3-D bar graph – MATLAB bar3

At least I sorta showed how to do some of it in the examples: It doesn’t error on the online version, but I can’t check if it makes the right plot unfortunately. Trial Software Product Updates. LineSpec bar bar3h barh. Description bar3 draws a three-dimensional bar graph.

Or say you wanted to color the bars using gradient according to their heights:. If you run the examples I showed above, you’ll find that some of the advanced 3D features are not yet implemented correctly in Octave this includes transparency, lighting, and such. I think the default C can be one solid colour as your function creates now. Select the China site in Chinese or English for best site performance.
