What is a Radar Chart?
A radar chart is an informative visual tool in which multiple variables (three or more) and compared on a two-dimensional plane. For this, we will create different axes emerging from a common central point. In most of the cases, all the axes are equally distributed and uniformly drawn from each other. Sometimes, the axes are also connected to each other to form different grids that make it easier for us to plot the spider chart.

What is a radar chart?
A radar chart is a method of graphing data in a two-dimensional diagram when there are multiple variables. You can use a radar chart to graph one group of variables or to compare multiple groups of the same variables. You graph each variable on axes you arrange equally around a central origination point. Gridlines connect the axes and make it easier to read the chart. When you connect each group of variables on the graph, the connections form a polygon.
What does a radar chart represent?
However, the radar chart may also represent data using different techniques of quantifying data. Understanding whether each category uses the same scales of measurement is important for determining how the categories relate to each other overall.
How to compare two radar charts?
Compare data: There are two primary methods you can use to compare data on a radar chart. The first is to set up a group of individual radar charts next to each other and compare the shapes on each to look for outliers. The other approach is to compare shapes by laying them directly on top of one another and changing the opacity so you can see each one. If you have several shapes that need comparison, it may be better to use the first approach. If you only need to compare two or three shapes, it may be easier to use the layover method.

Once all the information is in your workbook, select the data by highlighting it. 2 Select the radar chart you want to use: Next click on the button that says “Insert” on the top toolbar. Then select “Other Charts” and then “Radar.” Finally, pick the specific type of chart you want to use. 3 Excel creates the radar chart: Excel will produce the radar chart using the information you selected in step one. This chart will show the labels for each axis, but you can remove these labels if you prefer to make viewing easier. 4 Remove axis labels: If you want to remove the axis labels, right-click at the axis and select “Format Axis” from the context menu that pops up. A dialog box will open. In this box, select “None” in the “Axis Labels” drop-down menu, and then close the box.
