    • toHTML

    • computeScalePixelWidth

      public void computeScalePixelWidth()
      Computes the number of pixels between each value on the axis.

    • computeScalePixelWidthDataAxis

      public void computeScalePixelWidthDataAxis()

    • getOneUnitPixelSize

      public double getOneUnitPixelSize()
      Returns the number of pixels one value unit occupies.
      Returns:
      double the number of pixels one value unit occupies.

    • getZeroLineCoordinate

      public float getZeroLineCoordinate()
      Returns the screen coordinate of the zero line. This will not always be the same as the origin as not all charts start at zero. This is needed not only by the Axis, but some of the Chart implementations as well.
      Returns:
      float the screen pixel location of the zero line.

    • setZeroLineCoordinate

      public void setZeroLineCoordinate(float value)
      Sets the screen coordinate of the zero line. This will not always be the same as the origin as not all charts start at zero.
      Parameters:
      value - the screen pixel location of the zero line.

    • computeOneUnitPixelSize

      public void computeOneUnitPixelSize(float scalePixelLength, double increment)
      Computes the relationship of data point values to pixel values so know where along the axis a value is.
      Parameters:
      scalePixelLength -
      increment -
