JavaFX 2.0 :: BarChart Axis Tick-labels Missing With JDK1.8

Jul 10, 2014

Currently I try to integrate a JavaFX BarChart into my existing Java application. Therefore I need a BufferedImage of my BarChart, so that I can render that snapshot on a Graphics instance.

I adapted the existing BarChartSample.java (Chart Sample | JavaFX Tutorials and Documentation) and removed all animations. The code itselfs works fine but I identified one problem -> my TickLabels are missing

The TickLabels are visible If I use JDK 1.7u51 but if I change to JDK 1.8u05.... than the stlye of my BarChart will be changed and my tick labels are not visible.

Did I missed something or is that a bug?

using JDK 1.7u51
[URL] .....

using JDK 1.8u05
[URL] .....

My adapted code is the following:

package barchartsample;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.util.concurrent.Callable;
import java.util.concurrent.ExecutionException;
import java.util.concurrent.FutureTask;

[Code] .....

JavaFX 2.0 :: Reordering Barchart Elements

Mar 4, 2015

I am new to JavaFX. I would like to display a bar chart of items that are arranged according to their values.

I have the codes below that I call the function updateChart() after some user interaction. The list is sorted according to their values and on the 1st time the chart is populated, the order is displayed correctly.

However, when I pass in a new list with the same labels but with a different value, the bar chart is still displayed in the same order as the 1st time it is populated, even though I called clear().

@FXML
private BarChart<Number, String> certaintyFactorChart;
//update chart based on cf values
public void updateChart(List<AbstractMap.SimpleEntry<String, Double>> cfValues){
certaintyFactorChart.getData().clear();

[Code] ....

JavaFX 2.0 :: BarChart Wrong Data Displayed

Aug 28, 2014

I'm using BarChart and I've a very strange problem. Is not very simple create a test case to understand where is the problem.

In the first image is displayed a bar with the value of 2 but as you can see the y axis is not correct.

In the second image the value displayed is 4 but the y axis is completely busted.

Important thing: In my real app I change data of the chart every time the user change a combobox value (the period).

First image
Second image

This is a test case that simulate what I'm doing in my app with the only difference that data are fetched remotely with an async request in my real app.

Chart.java

public class Chart extends Application implements Initializable {
    @FXML
    private BarChart<String, Integer> chart;
    private ObjectProperty<ObservableList<Series<String, Integer>>> seriesProperty = new SimpleObjectProperty<ObservableList<Series<String, Integer>>>();

[Code] .....

Unfortunately with this simple test case the chart display correctly data.

JavaFX 2.0 :: Chart Axis Changing Color

Mar 20, 2015

I'm struggling to change the colour of the X and Y axis. I can change the colour of the ticks and the tick labels in CSS... But not the axis themselves.

JavaFX 2.0 :: Panel Effect - Rotation Along Its Y Axis

Dec 14, 2014

I have a UI widget, like a table view for example, displaying real-time data. This table can be configured - so it has many properties. The way I would like to do so, is to have a small 'configure button', once clicked, would rotate the entire table along its y axis, and display another panel with checkboxes etc... So effectively, the hidden properties panel is revealed by rotation.

Print Table (array) Where Have X Axis And Y Axis?

Apr 12, 2015

I want to print a table (array) where I have an X axis and a Y axis. 16x11. My code is as follows:

int Windchill [] [] = new int [16][11];
{
{60, 55, 50, 45, 40, 35, 30, 25, 20, 15, 10, 5, 0, -5, -10, -15} //X
{0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50} //Y
};

The code doesn't work even though it's similar to

int Windchill [][] =
{
{60, 55, 50, 45, 40, 35, 30, 25, 20, 15, 10, 5, 0, -5, -10, -15}, //X
{0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50}, //Y
};

if I remember correctly, the 2 are correct just written in different ways.

and I want it to print like this

{60, 55, 50, 45, 40, 35, 30, 25, 20, 15, 10, 5, 0, -5, -10, -15},
{ 0, 0, 0, 0, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0,
5, 0, 0, 0, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0,
10, 0, 0, 0, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0,
15, 0, 0, 0, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0,
20, 0, 0, 0, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0,
25, 0, 0, 0, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0,
30, 0, 0, 0, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0,
35, 0, 0, 0, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0,
40, 0, 0, 0, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0,
45, 0, 0, 0, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0,
50, 0, 0, 0, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0,}

where 0 is null (for now). I want to fill those in with a formula later, but I don't hardcoding them one by one is the most "efficient" way to do it

Modify Class Time2 To Include Tick Method That Increments Time Stored In Object By One Second

Jul 9, 2014

Modify class Time2 to include a tick method that increments the time stored in a Time2 object by one second. Provide method incrementMinute to increment the minute and method incrementHour to increment the hour. The Time2 object should always remain

a) incrementing into the next minute,

b) incrementing into the next hour and

c) incrementing into the next day (i.e., 11:59:59 PM to 12:00:00 AM).

how to manage case 4 stuff and what's the problem of this CODE.

import java.util.Scanner;
public class Time2Test
{
public static void main( String args[] )
{
Scanner input = new Scanner( System.in );
Time2 time = new Time2();
// input
System.out.println( "Enter the time" );
System.out.print( "Hours: " );
time.setHour( input.nextInt() );

Moving Object In Y Axis

Jul 10, 2014

I just have one problem with a "car" program in java. The objective is to move the car in the direction it is facing. Moving forward in the normal position (when the angle is zero) means moving in the x-axis. Choosing to turn the car function (for example: 90 ) and then using the forward function should move up or down the car in the y-axis. However the y-axis is not working.

Swing/AWT/SWT :: Getting Key Labels To Show In Textfield?

Apr 2, 2014

I am working on a keypad for a phone app for school. I cannot get the numbers from the keys to show up in the textField. I have made multiple tweaks, but think maybe my case statement is the problem?We did a calculator application in the class, so I have based my code off of that. Although the telephone keypad seemed much simpler to code, I can't seem to get the numbers to show up.

public void actionPerformed(ActionEvent e) {
//test for button clicks
foundKey = false;
//search for clicked key
for (int i=0; i<keys.length && !foundKey; i++)

Pong Game - Y Axis Collision Detection

Jan 28, 2014

I have made a "Pong" game and how to check if the ball has hit the top or the bottom of a paddle, however I do know how to check if it has hit the left or right side:

Java Code:

if((BALL.getX() >= LEFT_BAT.getX() && BALL.getX() <= LEFT_BAT.getX() + LEFT_BAT.getWidth()
&& BALL.getY() >= LEFT_BAT.getY() && BALL.getY() <= LEFT_BAT.getY() + LEFT_BAT.getHeight())
&& (BALL.getX() >= RIGHT_BAT.getX() && BALL.getX() <= RIGHT_BAT.getX() + RIGHT_BAT.getWidth()
&& BALL.getY() >= RIGHT_BAT.getY() && BALL.getY() <= RIGHT_BAT.getY() + RIGHT_BAT.getHeight())){
BALL.increaseDX();
BALL.setDX(-BALL.getDX());
} mh_sh_highlight_all('java');

It seems as though I would use the same code for checking the top or bottom.

Which Axis To Increment / Decrement With Inclusion Of Speed Variable

Jan 30, 2015

if I move object A to one area of the screen I want object B to to move to object A's location but I also want object B to move at a fixed speed (movement variable). How do I go about doing this? Both the x and y coordinates of object B would need to know the coordinates of object A to calculate the distance between the two and to determine how much of which axis to increment/decrement (if that makes sense?) with the inclusion of the speed variable.In other words I'm just trying to create a homing object.

Java Swing Project - Updating Labels And Other Stuff

May 28, 2014

I wrote a simple random spelling game for a class project, was never able to get the labels to update when they should. I have tried .updateUI, .paintImmediately followed by .revalidate and by .repaint. Nothing seems to be working.

What the game does is show a random word for about 10 seconds, disappear and they user is to spell that word, you have 3 tries then will start over. The "brains" of the game work just fine, it is the labels updating with new text when they should doesn't seem to be working. There is 4 classes but the below is the "Main" that has the problems. Also have a null exception problem with the timer.stop(); not sure why. I am still pretty new to java.

Public class SpellMe extends JFrame {
// variables
JPanel mainPanel, secondPanel, thirdPanel;
JLabel mainLabel, wordLabel;
String spWord, sp;
JTextArea guess;

Now, I need to divide the x & y axes with frequencies (Ex: On Y-axis: 0 10 20 30 40 etc ..) and then plot points (Ex: [34, 54] etc) accordingly.

Which methods to use or way out to make this implementation?

Drawing A Square In Quadrant I Grid - Axis Not Display Properly

Feb 3, 2015

Currently, I am trying to create a program that draws a square anywhere in a 15x15 Quadrant I (Coordinate plane) grid. I am stuck on trying to get the axes displaying correctly. This is the code I have thus far:

import java.util.Scanner;
public class Question2square {
public static void main(String[] args) {
// Axis variables
int yAxismin = 0;
int yAxismax = 15;

[Code] ....

Unfortunately, instead of drawing the 'L' shaped axes I desire, it displays an 'r' shape instead. I'm trying to figure out how to display the axis properly. I tried flipping the for loops but that didn't work. I don't see what else could be inhibiting this.

Vector Math - Calculate Equation Of A Plane That Would Rely On All Axis

Jan 27, 2014

I am running into some trouble with Line-Plane intersection, my method works, provided I am perpendicular to the plane I want to intersect. This is caused be the plane equation (with my given x, y, and z coordinates, the equation is -Z - 1 = 0). So the equation is only relying on the Z value of anything inputted. Is there another way to calculate the equation of a plane that would rely on all axis? Here is my current code:

Java Code:

Vector3f A = new Vector3f(0, 0, -1);
Vector3f B = new Vector3f(0, 1, -1);
Vector3f C = new Vector3f(1, 1, -1);

Vector3f v1 = new Vector3f(B.x - A.x, B.y - A.y, B.z - A.z);
Vector3f v2 = new Vector3f(C.x - A.x, C.y - A.y, C.z - A.z);

float[] i = new float[]{v1.x, v2.x};
float[] j = new float[]{v1.y, v2.y};
float[] k = new float[]{v1.z, v2.z};
