An array of the x-axis values for the third “y-axis” of the graph.After inserting the chart, I created three arrays: I also added some color to the axes and axis labels for clarity.įor an Excel graph with 3 variables, the third variable must be scaled to fill the chart. In that case, I would have had to use a different scaling factor. The scaled acceleration data could have been on the primary axis. I put the velocity and scaled acceleration data on the secondary axis of the chart. Next, I created a chart by selecting the angle, position, velocity, and scaled acceleration data. Select the Data for the 3 Axis Graph in Excel Of course, we can always change this later. I picked a value of 285 degrees, since the position, and therefore the velocity and acceleration, are zero beyond this point. The third y-axis (which will really be a data series) will be on the chart area, so it has to cross the x-axis at some point. See also Installing the Power Query Add In for Excel 2010/2013ĭecide on a Position for the Third Y-Axis To do this, I entered an appropriate scaling factor in the spreadsheet and created a new column of scaled acceleration data by multiplying the original acceleration data by the scaling factor. However, we’ll want to scale the acceleration data so that it fills the chart area. Scale the Data for an Excel Graph with 3 VariablesĮxcel allows us to add a second axis to a scatter chart and we’ll use this for velocity and acceleration. It’s not a perfect solution, but to my knowledge, it’s the best we can do in Excel with the currently available toolset. Unfortunately, there isn’t native functionality to create one, but we can fake an Excel graph with 3 variables by creating another data series with a constant x-value, like I’ve done in the image below. So he wanted to know if there was a way to create a 3 axis graph in Excel. This makes it hard to view the acceleration curve on the chart without a unique axis. The challenge is that all three curves have very different scales, with acceleration being the smallest. I’ll show all the steps necessary to create an Excel graph with 3 variables below. Multiple y-axis charts in Excel are straightforward if you only need to plot 2 y-axes but 3 y-axes take some more work and a little creativity. The industry-standard way of graphing this data is to include all three curves on the same chart, like in the image below, and he wanted create one like it in Excel. He uses Excel to create charts of cam position, velocity, and acceleration. Ever wanted to know how to create a 3 axis graph in Excel? The other day I got a question from Todd, an subscriber.
