public class ChartAxisType
- extends java.lang.Object
Utility class containing constants.
Specifies type of chart axis.
Example:
Shows how to pick an appropriate graph type for a chart series.
public void chartSeriesCollection() throws Exception {
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// There are 4 ways of populating a chart's series collection
// 1: Each series has a string array of categories, each with a corresponding data value
// Some of the other possible applications are bar, column, line and surface charts
Chart chart = appendChart(builder, ChartType.COLUMN, 300.0, 300.0);
// Create and name 3 categories with a string array
String[] categories = {"Category 1", "Category 2", "Category 3"};
// Create 2 series of data, each with one point for every category
// This will generate a column graph with 3 clusters of 2 bars
chart.getSeries().add("Series 1", categories, new double[]{76.6, 82.1, 91.6});
chart.getSeries().add("Series 2", categories, new double[]{64.2, 79.5, 94.0});
// Categories are distributed along the X-axis while values are distributed along the Y-axis
Assert.assertEquals(chart.getAxisX().getType(), ChartAxisType.CATEGORY);
Assert.assertEquals(chart.getAxisY().getType(), ChartAxisType.VALUE);
// 2: Each series will have a collection of dates with a corresponding value for each date
// Area, radar and stock charts are some of the appropriate chart types for this
chart = appendChart(builder, ChartType.AREA, 300.0, 300.0);
// Create a collection of dates to serve as categories

// Our sporadic dates will be distributed along the X-axis in a linear fashion

// 3: Each series will take two data arrays
// Appropriate for scatter plots
chart = appendChart(builder, ChartType.SCATTER, 300.0, 300.0);
// In each series, the first array contains the X-coordinates and the second contains respective Y-coordinates of points

// Both axes are value axes in this case
Assert.assertEquals(chart.getAxisX().getType(), ChartAxisType.VALUE);
Assert.assertEquals(chart.getAxisY().getType(), ChartAxisType.VALUE);
// 4: Each series will be built from three data arrays, used for bubble charts
chart = appendChart(builder, ChartType.BUBBLE, 300.0, 300.0);
// The first two arrays contain X/Y coordinates like above and the third determines the thickness of each point
chart.getSeries().add("Series 1", new double[]{1.1, 5.0, 9.8}, new double[]{1.2, 4.9, 9.9}, new double[]{2.0, 4.0, 8.0});
