GWT Highcharts 负值柱状图 介绍

我们已经在《GWT Highcharts 入门案例》一章中看到了用于绘制此图表的步骤。现在让我们考虑以下示例以进一步了解负值柱状图。

package com.yiidian.helloWorld.client;


import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.RootPanel;
import org.moxieapps.gwt.highcharts.client.*;
import org.moxieapps.gwt.highcharts.client.labels.DataLabels;
import org.moxieapps.gwt.highcharts.client.plotOptions.ColumnPlotOptions;

public class HelloWorld implements EntryPoint {
    public void onModuleLoad() {
        final Chart chart = new Chart()
                .setType(Series.Type.COLUMN)
                .setChartTitleText("Column chart with negative values");
        chart.getXAxis()
                .setCategories("Apples", "Oranges", "Pears", "Grapes", "Bananas");
        chart.addSeries(chart.createSeries()
                .setName("John")
                .setPoints(new Number[] { 5, 3, 4, 7, 2 })
        );
        chart.addSeries(chart.createSeries()
                .setName("Jane")
                .setPoints(new Number[] { 2, -2, -3, 2, 1 })
        );
        chart.addSeries(chart.createSeries()
                .setName("Joe")
                .setPoints(new Number[] { 3, 4, 4, -2, 5 })
        );
        RootPanel.get().add(chart);
    }
}

输出结果为：
