Scales and Grid Configuration

In this chapter, you will learn how to configure the scales that control how your chart is displayed in a Cartesian or radial grid. Scales are used in all charts except pie and doughnut. Cartesian charts, such as line, bar, scatter, and bubble, use a pair of perpendicular axes, each one with a scale automatically calculated by Chart.js to position data points. Data in charts, such as polar area and radar, use a single scale, placing the data points at different positions that originate from the center. You can configure scales, altering the way the data points are presented, for example, by using a logarithmic scale instead of a default linear scale for numerical values. You may also choose a sequential time scale instead of a category scale. There are also many ways to configure styles and change the way axes, grid lines, ticks, and labels are shown...
