In the pie chart, we represent the data values as slices of a circle. Each slice is differentiated from other (typically by color). In JavaFX, you can create a pie chart by instantiating the javafx.scene.chart.PieChart class.This class provides various properties, by setting values to them using their respective setter methods, you can customize the pie chart.The slices of the pie chart are placed clockwise (from the start angle) by default. You can arrange them anti-clockwise by setting the clockwise property to false, using the setClockwise() method.Each slice is associated with a label. (name of the slice as value) By default, these ... Read More
All the XY charts have an abstract method named layoutPlotChildren(). To color the plotted area (region) of an XY chart one way is to override this method. Generally, it is called to update and layout the plot of children.In the body of this method −Get the series data.Extract the plotted points.Draw a polygon in the plotted area using the extracted points.Set the desired color to the polygon.Exampleimport javafx.application.Application; import javafx.collections.FXCollections; import javafx.collections.ObservableList; import javafx.scene.Scene; import javafx.stage.Stage; import javafx.scene.chart.LineChart; import javafx.scene.chart.NumberAxis; import javafx.scene.chart.XYChart; import javafx.scene.chart.XYChart.Series; import javafx.scene.layout.StackPane; import javafx.scene.paint.Color; import javafx.scene.shape.Polygon; public class EnhancingGraphPlot extends Application { public void start(Stage ...

The javafx.scene.chart package provides classes to create various charts namely − line chart, area chart, bar chart, pie chart, bubble chart, scatter chart, etc.You can create the required chart by instantiating the respective class.Setting background image and the color −The -fx-background-color class of JavaFX CSS is used to set a colored background to a chart.The -fx-background-color (of the region chart-plot-background) class of JavaFX CSS is used to set the back ground color.JavaFX Scene class has an observable list to hold all the required style sheets. You can get this list using the getStylesheets() method.To set an image as a background ... Read More

The javafx.scene.chart package provides classes to create various charts namely &minusl line chart, area chart, bar chart, pie chart, bubble chart, scatter chart, etc.Except for pie chart, all other charts are plotted on the XY planes. You can create the required XY chart by instantiating the respective class.Changing the color of axis lines −The fx-border-color class of JavaFX CSS is used to set the color of the border of a node.The -fx-border-width class of JavaFX CSS is used to set the width of the border of a node.The setStyle() method of the Node (Base class of all the nodes) class ...

The javafx.scene.chart package of JavaFX provides classes to create various charts namely: line chart, area chart, bar chart, pie chart, bubble chart, scatter chart, etc..To create either of these charts you need to −Instantiate the respective class.Set the required properties.Create a layout/group object to hold the chart.Add the layout/group object to the scene.Show the scene by invoking the show() method.This will show the desired chart on the JavaFX window.Saving the image without showing the windowThe snapshot() method of the Scene class takes a snapshot of the current scene and returns it as a WritableImage Object.Using the FromFXImage() method of the ...

Transformation refers to a change on the node is in the XY plane. JavaFX supports four basic transforms namely −Scale − Increase or decrease the size.Rotate − Movement of the coordinates of a node around a fixed point with an angle.Translate − Movement of the node in the XY plane.Shear − Displacement of an object in a fixed direction such that its shape is slanted.Every node in JavaFX contains an observable list to hold all the transforms to be applied on a node. You can get this list using the getTransforms() method. You can also add multiple transforms to a node.ExampleThe ... Read More
In this tutorial, we will be discussing a program to find the root of an equation using secant method.For this we will be provided with an equation. Our task is to find the roots of that equation using the iterative secant method.Example Live Demo#include using namespace std; float f(float x) { float f = pow(x, 3) + x - 1; return f; } void secant(float x1, float x2, float E) { float n = 0, xm, x0, c; if (f(x1) * f(x2) < 0) { do { //calculating the ...

In this tutorial, we will be discussing a program to find prime numbers between given intervals.For this we would be provided with two integers. Our task is to find the prime numbers in that particular range.Example Live Demo#include using namespace std; int main() { int a, b, i, j, flag; //getting lower range a = 3; //getting upper range b = 12; cout
In this tutorial, we will be discussing a program to find parity.For this we will be provided with a number. Our task is to find its parity i.e count of whether the number of ones are odd or even.Example Live Demo# include # define bool int using namespace std; //finding the parity of given number bool getParity(unsigned int n) { bool parity = 0; while (n){ parity = !parity; n = n & (n - 1); } return parity; } int main() { unsigned int n = 7; cout
