Axes are an integral part of a chart. They are used to determine how data maps to a pixel value on the chart.
In a cartesian chart, there is 1 or more X axis and 1 or more Y axis to map points onto the 2 dimensional canvas. These axes are know as 'cartesian axes'.
Axes that follow a cartesian grid are known as 'Cartesian Axes'. Cartesian axes are used for line, bar, and bubble charts. Four cartesian axes are included by default.
- linear
- logarithmic
- category
- time
