    • Method Detail

      • setDefaultSeriesRenderStyle

        public PieStyler setDefaultSeriesRenderStyle​(PieSeries.PieSeriesRenderStyle chartPieSeriesRenderStyle)
        Sets the default series render style for the chart (line, scatter, area, etc.) You can override the series render style individually on each Series object.
        Parameters:
        chartPieSeriesRenderStyle -

      • isCircular

        public boolean isCircular()

      • setCircular

        public PieStyler setCircular​(boolean isCircular)
        Sets whether or not the pie chart is forced to be circular. Otherwise it's shape is oval, matching the containing plot.
        Parameters:
        isCircular -

      • getStartAngleInDegrees

        public double getStartAngleInDegrees()

      • setStartAngleInDegrees

        public PieStyler setStartAngleInDegrees​(double startAngleInDegrees)
        Sets the start angle in degrees. Zero degrees is straight up.
        Parameters:
        startAngleInDegrees -

      • getLabelsDistance

        public double getLabelsDistance()

      • setLabelsDistance

        public PieStyler setLabelsDistance​(double labelsDistance)
        Sets the distance of the pie chart's annotation where 0 is the center, 1 is at the edge and greater than 1 is outside of the pie chart.
        Parameters:
        labelsDistance -

      • setLabelType

        public PieStyler setLabelType​(PieStyler.LabelType labelType)
        Sets the Pie chart's annotation type
        Parameters:
        labelType -

      • isForceAllLabelsVisible

        public boolean isForceAllLabelsVisible()

      • setForceAllLabelsVisible

        public PieStyler setForceAllLabelsVisible​(boolean forceAllLabelsVisible)
        By default, only the labels that will "fit", as determined algorithmically, will be drawn. Otherwise, you can end up with annotations drawn overlapping. If `drawAllAnnotations` is set true with this method, it will override the algorithmic determination, and always draw all the annotations, one for each slice. You can also try playing around with the method `setStartAngleInDegrees` so the the slices are orientated in a more optimal way. You can also try changing the font size. Also, you can order the slices so that a small slice is followed by a larger slice, while setting this method with `true`.
        Parameters:
        forceAllLabelsVisible -

      • getDonutThickness

        public double getDonutThickness()

      • setDonutThickness

        public PieStyler setDonutThickness​(double donutThickness)
        Sets the thickness of the donut ring for donut style pie chart series.
        Parameters:
        donutThickness - - Valid range is between 0 and 1.

      • isSumVisible

        public boolean isSumVisible()

      • setSumFormat

        public PieStyler setSumFormat​(java.lang.String sumFormat)
        Set the Format to be applied to the sum, the default is just to display the sum as a number using the PieStyler DecimalFormat. This allows a separate Formatter @see java.util.Formatter#format()
        Parameters:
        sumFormat - Format to use for the sum display, the Double sum value will be passed to this to generate the overall sum string.
        Returns:
        PieStyler so that modifiers can be chained.

      • getSumFormat

        public java.lang.String getSumFormat()
        Access the current sumFormat value, a value of "" or null implies use the original sum formatted using the PieStyler DecimalFormat.
        Returns:
        Formatter string to be used when displaying the sum value or null
