我有一个XY图集在Y轴上以线性步骤绘制数据, 我想用对数或半对数Y比例来绘制数据, 如何修改我的以下代码?
public class BaseXYChart extends Application {
@Override
public void start(Stage stage) {
stage.setTitle("Linear plot");
final CategoryAxis xAxis = new CategoryAxis();
final NumberAxis yAxis = new NumberAxis(1, 22, 0.5);
yAxis.setTickLabelFormatter(new NumberAxis.DefaultFormatter(yAxis){
@Override
public String toString(Number object){
return String.format("%7.2f", object);
}
});
final LineChart<String, Number>lineChart = new LineChart<String, Number>(xAxis, yAxis);
lineChart.setCreateSymbols(false);
lineChart.setAlternativeRowFillVisible(false);
XYChart.Series series1 = new XYChart.Series();
series1.getData().add(new XYChart.Data("Jan", 1));
series1.getData().add(new XYChart.Data("Feb", 1.5));
series1.getData().add(new XYChart.Data("Mar", 2));
series1.getData().add(new XYChart.Data("Apr", 2.5));
series1.getData().add(new XYChart.Data("May", 3));
series1.getData().add(new XYChart.Data("Jun", 4));
series1.getData().add(new XYChart.Data("Jul", 6));
series1.getData().add(new XYChart.Data("Aug", 9));
series1.getData().add(new XYChart.Data("Sep", 12));
series1.getData().add(new XYChart.Data("Oct", 15));
series1.getData().add(new XYChart.Data("Nov", 20));
series1.getData().add(new XYChart.Data("Dec", 22));
BorderPane pane = new BorderPane();
pane.setCenter(lineChart);
Scene scene = new Scene(pane, 800, 600);
lineChart.getData().addAll(series1);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
谢谢大家多谢
