如何用字符串替换Bar GraphView底部的数字？

Question

我正在使用jjoe64 GraphView库在我的应用中创建一个GraphView栏。

当我创建一个新的DataPoint时，它需要2个值：X int和Y int，如下所示：

GraphView graph = (GraphView) findViewById(R.id.graph);
BarGraphSeries<DataPoint> series = new BarGraphSeries<DataPoint>(new DataPoint[] {
    new DataPoint(0, -1),
    new DataPoint(1, 5),
    new DataPoint(2, 3),
    new DataPoint(3, 2),
    new DataPoint(4, 6)
});
graph.addSeries(series);

如何使用字符串替换底部的X int？

Answer 1

你叫什么＆＃34;底部＆＃34;是＆＃34; X轴＆＃34;。要标记它，请使用

StaticLabelsFormatter staticLabelsFormatter = new StaticLabelsFormatter(graph);
staticLabelsFormatter.setHorizontalLabels(new String[] {"old", "middle", "new"});
graph.getGridLabelRenderer().setLabelFormatter(staticLabelsFormatter);

进一步阅读：Documentation

或者如果您使用GraphView 3.x：

graphView.setHorizontalLabels(new String[] {"0.5", "1", "1.5", "2.0"});
