# Plot XYZ in Tableau

Before anyone starts the "3D is bad practice" lecture, I don't want a 3D bar chart or something similarly stupid.  And I'm sure someone can think of a better way to represent my data than a simple XYZ scatter plot.  However this is such a basic, expected visualization within my community that without it, my higher ups will never shell out a penny for Tableau.

I just need to create a lat/long/time and lat/long/altitude chart.  Anyone know how?

Can you provide some sample data and the expected visualization with it?

Can't provide my real data or viz.  But here is some dummy data I created real quick in Matlab

Hi Megan,

There isn't a lot I could work out with 3 columns of data (and 2 of them were lat/long), but I found a correlation between your z numbers and their respective lat/long

If you let us know what type of visualization you are looking for, it would be easier. I just went with something that looked a little like your example post.

I am trying to create the visualization that I provided.  A simple scatter plot with 3 axes.  The data I attached is just dummy data.  I created a random z and then used it to create the x & y (hence the correlation).  Rigged it up in Matlab in about 10 seconds.

I'm not sure what you are trying to show in your visualization but I don't want a static 2D plot with a color and/or size for the 3rd dimension.  I need to know how to force Tableau to create 3rd axis.

Hi Megan, did you end up getting a solution to this problem? I'm looking for something similar.....

I found this blog that gives some examples of 3D visualizations:

While very clever (and I truly was impressed by the creativity of the creator of the 3D visualizations in the above example), they are practically useless. In any graphing program (not just Matlab) but even in stupid Excel and other programs like JMP, Origin, Igor Pro etc, I can easily plot scatter or surface plots in seconds. This solution requires creating bunch of new variables, doing math and a lot of gymnastics to get a pseudo-3D visualization of the data.

I would say the clever developers at Tableau should just provide various 3D options (surface, scatter, mesh, contour) as a built-in graphing option.

我也覺得3D有多維度分析中是很重要的功能..

最近有一個案例需要分析多維度的效能關系曲線...只能用EXCEL作出不好看的3D分析

使用Tableau 怎麼都很難作到很好的曲線變化分析..
