JavaFX 2.1: javafx.scene.chart.StackedBarChart

JavaFX 2.1 introduce a new StackedBarChart class. StackedBarChart is a variation of BarChart that plots bars indicating data values for a category. The bars can be vertical or horizontal depending on which axis is a category axis. The bar for each series is stacked on top of the previous series.

Define the range and space of NumberAxis in JavaFX charts

In the last post of StackedAreaChart, the month axis is displayed from 0~13. In order to specify the horizontal axis, we can use 3-parameters/4-parameters constructor of NumberAxis.

public NumberAxis(double lowerBound, double upperBound, double tickUnit)
Create a non-auto-ranging NumberAxis with the given upper bound, lower bound and tick unit.
Parameters:

• lowerBound - The lower bound for this axis, ie min plottable value
• upperBound - The upper bound for this axis, ie max plottable value
• tickUnit - The tick unit, ie space between tickmarks

Example:

package javafx21;

import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.chart.NumberAxis;
import javafx.scene.chart.StackedAreaChart;
import javafx.scene.chart.XYChart;

JavaFX 2.1: javafx.scene.chart.StackedAreaChart

JavaFX 2.1 introduce a new StackedAreaChart class. StackedAreaChart is a variation of AreaChart that displays trends of the contribution of each value. (over time e.g.) The areas are stacked so that each series adjoins but does not overlap the preceding series. This contrasts with the Area chart where each series overlays the preceding series. The cumulative nature of the StackedAreaChart gives an idea of the total Y data value at any given point along the X axis. Since data points across multiple series may not be common, StackedAreaChart interpolates values along the line joining the data points whenever necessary.

In the example, some column in series 2 are missed. From the graph, it can be noticed how JavaFX display the StackedAreaChart with missed column.

Apply shadow on charts

To add shadow on charts, we can create a Shadow object, and apply on charts using setEffect() method.

Example:

package javafx_charts;

import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.chart.AreaChart;
import javafx.scene.chart.CategoryAxis;
import javafx.scene.chart.NumberAxis;
import javafx.scene.chart.XYChart;
import javafx.scene.effect.BlurType;
import javafx.scene.effect.DropShadow;
import javafx.scene.paint.Color;
import javafx.stage.Stage;

        Group root = new Group();

        yAxis.setLabel("Value");
        
        final AreaChart<String,Number> areaChart = new AreaChart<>(xAxis,yAxis);

        areaChart.setTitle("AreaChart");
        XYChart.Series series = new XYChart.Series();
        series.setName("XYChart.Series");
        
        series.getData().add(new XYChart.Data("January", 100));

        DropShadow dropShadow = new DropShadow();
        dropShadow.setOffsetX(5);
        dropShadow.setOffsetY(10);
        dropShadow.setColor(Color.GRAY);
        dropShadow.setBlurType(BlurType.GAUSSIAN);
        areaChart.setEffect(dropShadow);
            
        root.getChildren().add(areaChart);

Create and update PieChart from TableView

In previous article, I demonstrate how to create PieChart and Editable TableView. They will be merged in this article to make the PieChart update with Table.




First of all, compare my Record class in last article of Editable TableView and PieChart.Data of JavaFX 2.0. We can replace Record in the TableView with PieChart.Data.

Then we can easy to create PieChart using with dataList of ObservableList<PieChart.Data>. When the content of dataList changed, the PieChart will change accordingly.

JavaFX 2: TableView

JavaFX provide API of TableView, TableColumn, and TableCell to help creating tables. You can populate a table by implementing the data model and by applying a cell factory.

The table classes provide built-in capabilities to sort data in columns and to resize columns when necessary.

It's a example of JavaFX 2 TableView.



Please note that the setCellValueFactory() method specifies a cell factory for each column. It uses the "fieldMonth", "fieldValue" properties of the table columns as references to the corresponding methods of the Record class. It assume that there are callback method named getFieldMonth() and getFieldValue() in Record class. Remark - if you name it getfieldMonth() and getfieldValue(); it will not work!

JavaFX 2: Change scale in runtime

To change scale (ex. of a Rectangle) in runtime, call setScaleX(double) and setScaleY(double) methods.

In this example, user can press and drag the mouse to change the scale of the rectangle at runtime.

JavaFX Scene Builder - A Visual Layout Tool for JavaFX Applications

JavaFX Scene Builder is a visual layout tool that lets users quickly design JavaFX application user interfaces, without coding. Users can drag and drop UI components to a work area, modify their properties, apply style sheets, and the FXML code for the layout that they are creating is automatically generated in the background. The result is an FXML file that can then be combined with a Java project by binding the UI to the application’s logic.

• UI Layout Tool
  Scene Builder allows you to easily layout JavaFX UI controls, charts, shapes, and containers, so that you can quickly prototype user interfaces. Animations and effects can be applied seamlessly for more sophisticated UIs.


• Integrated Developer Workflow
  Scene Builder can be used in combination with any Java IDE, but is more tightly integrated with NetBeans IDE. You can bind the UI to the source code that will handle the events and actions taken on each element through a simple process, run your application in NetBeans, and any changes to FXML in NetBeans will also reflect in your Scene Builder project.


• Windows and Mac OS X
  Scene Builder is written as a JavaFX application, with native desktop integration on Windows and Mac OS X.
  It is the perfect example of a full-fledge JavaFX desktop application.


• FXML Visual Editor
  Scene Builder generates FXML, an XML-based markup language that enables users to define an application’s user interface, separately from the application logic. You can also open and edit existing FXML files authored by other users.


• Preview Your Work
  At any time during the creation of your project, you can preview what the user interface will really look like when deployed, unencumbered by the tool’s menus and palettes.


• CSS Support
  You can apply the look and feel of your choice to your GUI layout by using style sheets. It’s as easy as selecting a GUI component, and pointing to the CSS file of your choice from the Properties Panel.
