public class AxisScaleType
Specifies the possible scale types for an axis.
Examples:
Shows how to apply logarithmic scaling to a chart axis.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
Shape chartShape = builder.insertChart(ChartType.SCATTER, 450.0, 300.0);
Chart chart = chartShape.getChart();
// Clear the chart's demo data series to start with a clean chart.
chart.getSeries().clear();
// Insert a series with X/Y coordinates for five points.
chart.getSeries().add("Series 1",
new double[]{1.0, 2.0, 3.0, 4.0, 5.0},
new double[]{1.0, 20.0, 400.0, 8000.0, 160000.0});
// The scaling of the X-axis is linear by default,
// displaying evenly incrementing values that cover our X-value range (0, 1, 2, 3...).
// A linear axis is not ideal for our Y-values
// since the points with the smaller Y-values will be harder to read.
// A logarithmic scaling with a base of 20 (1, 20, 400, 8000...)
// will spread the plotted points, allowing us to read their values on the chart more easily.
chart.getAxisY().getScaling().setType(AxisScaleType.LOGARITHMIC);
chart.getAxisY().getScaling().setLogBase(20.0);
