I'd like to create horizontal scrolling linechart
with a locked y axis on JAVAFX . I have been searching an example or something similar but I did not find anything with JAVAFX. I try to put the linechart
into a scrollpane
but all is moving right and left when I scroll (of course) and I want to see always at least the legend and the y axis...
Any ideas? Thank you!
For example on chart.js something like this:
Hi i created a new Application which does what you want. The trick is, that you set the minHeight of the chart smaller than the size of the ScrollPane because the ScrollPane needs Space for the Scrollbar. Here my example:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.chart.LineChart;
import javafx.scene.chart.NumberAxis;
import javafx.scene.chart.XYChart;
import javafx.scene.control.ScrollPane;
import javafx.stage.Stage;
public class LineChartSample extends Application {
@Override public void start(Stage stage) {
stage.setTitle("Line Chart Sample");
//defining the axes
final NumberAxis xAxis = new NumberAxis();
final NumberAxis yAxis = new NumberAxis();
xAxis.setLabel("Number of Month");
//creating the chart
final LineChart<Number,Number> lineChart =
new LineChart<>(xAxis, yAxis);
lineChart.setTitle("Stock Monitoring, 2010");
//defining a series
XYChart.Series series = new XYChart.Series();
series.setName("My portfolio");
//populating the series with data
series.getData().add(new XYChart.Data(1, 23));
series.getData().add(new XYChart.Data(2, 14));
series.getData().add(new XYChart.Data(3, 15));
series.getData().add(new XYChart.Data(4, 24));
series.getData().add(new XYChart.Data(5, 34));
series.getData().add(new XYChart.Data(6, 36));
series.getData().add(new XYChart.Data(7, 22));
series.getData().add(new XYChart.Data(8, 45));
series.getData().add(new XYChart.Data(9, 43));
series.getData().add(new XYChart.Data(10, 17));
series.getData().add(new XYChart.Data(11, 29));
series.getData().add(new XYChart.Data(12, 25));
ScrollPane root = new ScrollPane(lineChart);
root.setMinSize(1000,600);
lineChart.setMinSize(root.getMinWidth(),root.getMinHeight()-20);
Scene scene = new Scene(root,800,600);
lineChart.getData().add(series);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
