                                     AxisTypeProperties axisTypeProperties)
        Computes the number of pixels between each value on the axis. public void computeScalePixelWidth( int numberOfValuesOnXAxis ) { super.setScalePixelWidth( super.getPixelLength() / numberOfValuesOnXAxis ); } /****************************************************************************************************
        Parameters:

        Determines if we should start x-axis ticks at the y-axis or space it out a half a scale item width.
        Parameters:
        iAxisDataSeries -
        axisTypeProperties -
      • computeTickStart

        public void computeTickStart()
        Computes the screen pixel location of the first tick mark
      • computeScalePixelWidth

        public void computeScalePixelWidth()
        Computes the number of pixels between each value on the axis.
        Overrides:
        computeScalePixelWidth in class Axis
      • render

        public void render​(java.awt.Graphics2D graphics2D,
                           AxisProperties axisProperties,
                           java.lang.String axisTitle)
        Renders the YAxis on the passes Graphics2D object
        Parameters:
        graphics2D -
        axisProperties -
        axisTitle -
      • computeLabelFilter

        public void computeLabelFilter()
        Method to compute the filter to use on the x-axis label display so labels do not overlap
      • toHTML

        public void toHTML​(HTMLGenerator htmlGenerator)
        Enables the testing routines to display the contents of this Object.
        Specified by:
        toHTML in interface HTMLTestable
        Overrides:

      • computeAxisCoordinate

        public float computeAxisCoordinate​(float origin,
                                           double value,
                                           double axisMinValue)
        Takes a value and determines the screen coordinate it should be drawn at. THe only difference between this and the y-axis is we add to the origin versus subtract from it.
        Parameters:
        origin -
        value -
        axisMinValue - the minimum value on the axis
        Returns:
        float the screen pixel coordinate
