Here’s how you do that quickly and easily. Since CSAT scores are also measured on the percentage scale, simply divide each CSAT score table by 10. The polar plot will be made up of 10 data rings, each radial point (the distance between the inner and outer edge of a ring) representing a ten percent increment on a scale from 0 to 100. Now execute the formula for the rest of the cells in the column ( F5:F14) by selecting F4 and dragging down the fill handle. It is important to lock the cell range ( A3:A14) to easily copy the formula into the remaining cells.
With that formula in cell F3, use this other formula in cell F4 to add up a given Angle value to the sum of all the theta values that go before it in the column: =F3+360/COUNTA($A$3:$A$14) Basically, it counts the number of cells that are not empty within the specified range.Ĭopy this formula into cell F3: =360/COUNTA($A$3:$A$14) And that’s where the COUNTA function comes into play. Then, add up that number as you go along from zero to all the way to 360.

As one full circular rotation equals 360 degrees, to pull off the task, you have to divide 360 by the number of categories in your dataset (in our case, twelve months). In this step, our aim is to evenly map out the spokes based on the number of categories in the dataset. If you already have your r and theta values figured out, skip this part and scroll down to Step #4. Step #2: Compute the Angle (theta) values.
To build the plot, you need to compute the polar coordinates first and, once there, convert them to the x- and y-axis values used by Excel to create the chart. Right off the bat, outline a helper table where all the calculations for your chart will take place. Since CSAT scores are commonly expressed as a percentage scale, consider the following table: For the record, this article is based on the tutorial created by Jon Peltier.

In this in-depth, step-by-step tutorial, you will learn how to turn your raw data into a polar plot in Excel from the ground up. Also, don’t forget to check out the Chart Creator Add-In, a powerful tool for building mind-blowing advanced Excel charts and graphs in just a few clicks. The plot enables you to quickly assess the good and bad months for each company, which facilitates better decision making.Įxcel doesn’t support this chart type-in fact, it can’t even read polar coordinates-meaning you will have to build it from scratch. The polar plot comes in handy when the analyzed data has a cyclical nature.Īs an example, the chart below compares the customer satisfaction scores (CSAT), a metric that illustrates a customer’s satisfaction with a brand or product, of two organizations throughout 2019: Simpson Ltd and Griffin Ltd. The plane itself is made up of concentric circles expanding outward from the origin, or the pole-hence the name. Theta (θ) – The angle from a reference angle.Radius ( r) – The distance from the center of the plot.Step #13: Remove the gridlines, the axes, and the irrelevant legend items.Ī polar plot is used to define a point in space within what is called the polar coordinate system, where rather than using the standard x- and y-coordinates, each point on a polar plane is expressed using these two values:.
