With the equation(s) above you can graph XYZ values on a 2D graph in X and Y. That is the tricky part, and the equation is broken down for you on the right: Therefor you need to convert XYZ into just XY. Excel can only graph two points of data at one time (X and Y). There are several different equations you need in order to graph XYZ data inside Excel. He offers many tutorials on this and we highly suggest you visit his page if you have an interest in creating amazing graphs using Excel Excel Unusual. George Lungu has done an amazing job explaining the mathematic equations behind 3D graphing inside of Microsoft Excel. Simply put, we really do not feel like recreating the wheel. This method is very complicated, and we will do a brief job explaining the complexities of this. When you are dealing with wider areas like geographical data, you really should be using surface graphs. When you are creating 3D data in Excel, which we outline in the next section, you need to convert the data into 2D data. You see, Excel was not created to plot things in 3D. What I mean, if you have a set of 20, 30 or 40 data points close together, then it plots great! If you are plotting, say, Lat. Something to know about XYZ Mesh’s scatter plots is that it is really good with data that is close together and now wide spread. That’s it! Once loaded you will see a new Excel document with your 3D plot rotation, zoom and pan bars included! In this new window select ‘3D Line’ or ‘3D Scatter’, and then ‘Export to Excel’. Simply add in your X Y Z values into XYZ Mesh and click ‘Excel 3D Export’. XYZ Mesh makes plotting 3D scatter plots in Excel easy. After we figured that hurtle, we moved to plotting X Y Z scatter plots in 3D. XYZ Mesh was originally made to take X Y Z data and convert it into a MESH format compatible with Excel. Yes, XYZ Mesh again, but, when you dedicate over 10 years to make an application that does one thing, it does that one thing pretty good! How to plot XYZ data in 3D – Scatter Plot and 3D Lines in Excel If you skip this part than Excel will assume your empty data points are zero and your graph will look like this (image to the right ->). You need to calculate the differences between values to get a correct curving of the data. The reason why is because you are going to need to track down and paste every single Z value in the correct place to make this MESH format graph properly. To get a better understanding of this, please see the image provided below:Īs the image above illustrates, the X and Y values are easy enough to place, however the Z values will take time. X values are set stationary in the first column of every row, Y values are set stationary in the first row of every column and Z values are placed exactly where the X means the Y for the corresponding Z value. A MESH format is a structure that contains rows and columns, much like a spread sheet. In order for Excel to plot this into a 3D Surface graph the data must be in a MESH format. First thing you need to realize is that XYZ data is plotted in three columns, X, Y and Z. This is the section where we teach you how to accomplish the curving yourself. This oversite can cause data to be plotted incorrectly, which is why using XYZ Mesh is very important for creating smooth data. While this might be true in some instances (where zero means nothing), as far as numbers are concerned, zero is an actual number. (Surface) Method 2: DIY – Placing values! And one formula…Īs previously mentioned, Excel has a nasty habit of thinking that no values are the same as zero. Fast and easy conversions with curving and none of the hassle associated with the next portion of this post…. From here the data can be exported into Excel. In no time the data is converted and displayed for you in a preview window, displaying a wireframe mesh, surface graph, heat chart, or many other graphing options. But, for 99% of users, the default settings are perfect! Simply paste your values into the corresponding X, Y and Z columns, select your settings and click convert. Of course, there are many customization options inside of XYZ Mesh color variation, decimal replacements, user preferences, etc. XYZ Mesh is currently the only software available that will take XYZ data and convert it directly into Excel’s MESH format with data curving. This means that instead of simply skipping these values (like most graphing engines would do), Excel reads them as zeros ‘0’, and in return inputs false data into the graphed picture. Why are the missing data points such a big issue? Microsoft Excel looks at these empty data points as data and not missing values.
