What is a chart Axis in Excel?

A chart axis works like a reference line or scale for data plotted in a chart. Excel has two primary types of chart axes. The first type is called a value axis, which is used to plot numeric data. Often, the vertical axis in a chart is a value axis. The other primary axis type is called a category axis, which often appears as a horizontal axis.

What types of charts do not use axes?

Bubble, radar, and pie charts are some chart types that do not use axes to display data. In addition to horizontal and vertical axes, 3-D charts have a third axis. The z-axis, also called the secondary vertical axis or depth axis, plots data along the third dimension (the depth) of a chart.

How many axes does a two dimensional chart have?

Excel's standard two dimensional charts have two axes, as you can see in these examples of a bar chart, column chart, line chart, and area chart. Many chart types allow a secondary vertical axis. In this example, a secondary vertical axis is used to plot net profit. So, in this case the chart has 3 axes.

What axis does a 3D chart have?
