    CartesianCategoryAxis, CartesianLinearAxis, CartesianLogarithmicAxis, CartesianTimeAxis

    public abstract class CartesianAxis<T extends org.pepstock.charba.client.configuration.CartesianTick>
    extends Axis
    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.

    • logarithmic
    • category

      • setPosition

        public void setPosition​(AxisPosition position)
        An axis can either be positioned at the edge of the chart, at the center of the chart area, or dynamically with respect to a data value.
        To position the axis at the edge of the chart, set the position option to one of: 'top', 'left', 'bottom', 'right'.
        To position the axis at the center of the chart area, set the position option to 'center'.
        Parameters:
        position - position of axis
      • getPosition

        public AxisPosition getPosition()
        An axis can either be positioned at the edge of the chart, at the center of the chart area, or dynamically with respect to a data value.
        To position the axis at the edge of the chart, set the position option to one of: 'top', 'left', 'bottom', 'right'.
        To position the axis at the center of the chart area, set the position option to 'center'.
        Returns:
        position of axis.
