Examples of org.jfree.chart.axis.NumberAxis

org.jfree.chart.axis.NumberAxis
An axis for displaying numerical data.
If the axis is set up to automatically determine its range to fit the data, you can ensure that the range includes zero (statisticians usually prefer this) by setting the autoRangeIncludesZero flag to true.
The NumberAxis class has a mechanism for automatically selecting a tick unit that is appropriate for the current axis range. This mechanism is an adaptation of code suggested by Laurence Vanhelsuwe.

            domainAxis.setCategoryLabelPositions(CategoryLabelPositions.UP_90);
            domainAxis.setLowerMargin(0.0);
            domainAxis.setUpperMargin(0.0);
            domainAxis.setCategoryMargin(0.0);


            final NumberAxis rangeAxis = (NumberAxis) plot.getRangeAxis();
            ChartUtil.adjustChebyshev(dataset, rangeAxis);
            rangeAxis.setStandardTickUnits(NumberAxis.createIntegerTickUnits());
            rangeAxis.setAutoRange(true);


            StackedAreaRenderer ar = new StackedAreaRenderer2() {
                @Override
                public Paint getItemPaint(int row, int column) {
                    ChartLabel key = (ChartLabel) dataset.getColumnKey(column);
