我想創建溫度圖表,以便在實時溫度下進行監視。更改不同值的圖表顏色
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.chart.NumberAxis;
import javafx.scene.chart.StackedAreaChart;
import javafx.scene.chart.XYChart;
import javafx.stage.Stage;
public class MainApp extends Application
{
final NumberAxis xAxis = new NumberAxis(1, 31, 1);
final NumberAxis yAxis = new NumberAxis();
final StackedAreaChart<Number, Number> sac
= new StackedAreaChart<Number, Number>(xAxis, yAxis);
@Override
public void start(Stage stage)
{
setUserAgentStylesheet(STYLESHEET_CASPIAN);
stage.setTitle("Area Chart Sample");
sac.setTitle("Temperature Monitoring (in Degrees C)");
XYChart.Series<Number, Number> seriesApril
= new XYChart.Series<Number, Number>();
seriesApril.setName("April");
seriesApril.getData().add(new XYChart.Data(1, 4));
seriesApril.getData().add(new XYChart.Data(3, 10));
seriesApril.getData().add(new XYChart.Data(6, 15));
seriesApril.getData().add(new XYChart.Data(9, 8));
seriesApril.getData().add(new XYChart.Data(12, 5));
seriesApril.getData().add(new XYChart.Data(15, 18));
seriesApril.getData().add(new XYChart.Data(18, 15));
seriesApril.getData().add(new XYChart.Data(21, 13));
seriesApril.getData().add(new XYChart.Data(24, 19));
seriesApril.getData().add(new XYChart.Data(27, 21));
seriesApril.getData().add(new XYChart.Data(30, 21));
XYChart.Series<Number, Number> seriesMay
= new XYChart.Series<Number, Number>();
seriesMay.setName("May");
seriesMay.getData().add(new XYChart.Data(1, 20));
seriesMay.getData().add(new XYChart.Data(3, 15));
seriesMay.getData().add(new XYChart.Data(6, 13));
seriesMay.getData().add(new XYChart.Data(9, 12));
seriesMay.getData().add(new XYChart.Data(12, 14));
seriesMay.getData().add(new XYChart.Data(15, 18));
seriesMay.getData().add(new XYChart.Data(18, 25));
seriesMay.getData().add(new XYChart.Data(21, 25));
seriesMay.getData().add(new XYChart.Data(24, 23));
seriesMay.getData().add(new XYChart.Data(27, 26));
seriesMay.getData().add(new XYChart.Data(31, 26));
Scene scene = new Scene(sac, 800, 600);
sac.getData().addAll(seriesApril);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args)
{
launch(args);
}
}
我想改變圖表的高度溫度的顏色。例如,我想看到綠色的溫度在10到20之間,紅色的溫度在40到50之間。你能幫我實施嗎?
我如何將它實現爲Java代碼。我想用Java代碼動態地改變它,所以不能使用CSS的選項。 –
