Why can't I can't modify a Chart from the .fxml in my Controller?
I defined a BarChart in my .fxml file that i inject into my controller using the @FXML annotation. But when I insert a data series, the chart still shows up as empty in my application, even though debugger output confirms that I successfully insert the data series into my chart. Do I need to tell the chart's view to update somehow?
I could surely just work around the problem by getting a pane from the fxml into which I would then insert the chart (that does work, and I used this workaround in the past). But I'm curious about what I'm doing wrong.
Thanks for your help!
Controller code:
@FXML private BarChart<Number,String> barChart;
//...
barChart.getData().add( new XYChart.Series<Number,String>("blabla",
eventService
.getTopTen(EventType.MUSICAL)
.entrySet()
.stream()
.map(entry -> new XYChart.Data<>((Number)entry.getValue(),entry.getKey().getName(),entry))
.collect(Collectors.collectingAndThen(toList(), FXCollections::observableArrayList))
));
My FXML:
//...
<AnchorPane prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/10.0.1" xmlns:fx="http://javafx.com/fxml/1" fx:controller="at.ac.tuwien.inso.sepm.ticketline.client.gui.event.EventTopTenController">
<children>
<Button layoutX="267.0" layoutY="361.0" mnemonicParsing="false" onAction="#MusicalTopTenButtonHandler" text="Literature" />
<BarChart fx:id="barChart" layoutX="52.0" layoutY="14.0" prefHeight="338.0" prefWidth="510.0">
<xAxis>
<NumberAxis side="BOTTOM" />
</xAxis>
<yAxis>
<CategoryAxis side="LEFT" />
</yAxis>
</BarChart>

You can use highcharts library instead of this. It support json format which can simplify your problem.

I figured it out already. I had the fxml loaded into my program twice, by mistake. After calling the method in the controller, one of those Nodes was updated, the other one wasn't. I was just looking at the one that wasn't. Thanks anyways!
