I want to create 4 quadrants on a bubble chart. How can I do that. I have already created by bubble chart. The quadrant chart using JFreeChart is given here (Dave Gilbert's Weblog : Weblog) but I want to create it using JavaFX charting.
View RepliesI have to make a flowchart that shows a bubble sort. Here is the exact directions: provide a flowchart for a bubble sort, and write the pseudo-code that corresponds to the flowchart. You can assume the existence of a swapElement method (ie. use the predefined process symbol).one that does one pass through the array and returns a boolean if items were swapped (I'll call this the one pass method) another method that repeatedly calls the one pass method until that method returns false.This means that your flowchart will have two separate pieces for the one pass method and for the overall flow of the program (this one would use the predefined process symbol for the one pass method).
I have looked up what a bubble sort. It says it is another type of sort that involves repeatedly stepping through the array comparing adjacent items and swapping them if they are in the wrong order.The sort steps through the list multiple times until no swaps are needed, at which point the list is sorted.
I need to create a chart for work and comes across this sample from mbostock's chord diagram (bl.ocks.org/mbostock/4062006).
I only need to revise the tick label (names, display positions) but I don't know how to do it as I have 0 experience with Java.
My sample data for the var matrix is
[0,100,100,100]
[0,0,99,98]
[0,0,92,84]
[0,99,0,0]
which shows flows between country A, B, C and D.
I would like to revise the tick labels, so that:
1) Instead of showing 0K 5K 10K, I would like to show the country names (A - D), with no number or tick. I figured out this one by just commenting out all the codes relating to ticks.
2) Place the country names in the center of the arch. I don't know how to do this one.
I'm creating a small program that will be able to chart data that will be transmitted from a sensor device connected to the USB port. I would like to create a running chart that will display the data sequentially with respect to time.

I am not sure how to implement the runLater function and display the data. What should I hope to accomplish using the ranLater function? I understand that I need to an XYChart.Series to keep a continuously modifying chart, but other than that I'm not sure how to implement it.
I have this class and I want to pass "pergunta" from another class:
Java Code:
here* = if I put a number, the code works. I want to receive the parameter "pergunta" here but I can't put a parameter in start .
I want to populate the array pergunta in a previous class and use in this one.

Using the sample, I tried to create a horizontal stacked bar chart, but it didn't render correctly. Only a sliver of one bar shows and cosmetically the bar's rounded corners are at the top instead of the right side.
@Override
public void start(Stage primaryStage) {
String austria = "Austria";
String brazil = "Brazil";
NumberAxis xAxis = new NumberAxis();
xAxis.setLabel("Value");
xAxis.setTickLabelRotation(90);
[Code] ....
Oddly, if I change the second series to this, then only one bar shows:
series2.getData().add(new XYChart.Data(10, austria));
series2.getData().add(new XYChart.Data(15, brazil));
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.

I'm creating UI's that run on top of backend tools that can run from seconds to days and output GB's of generated data (imagine running tar on the Google servers).
I understand how to execute my backed tools using a runtime process and how to interact with them, and running a simple text as a command line Java app works as expected. The issue occurs when I wrap the code in a JavaFX frount end UI try to update the UI elements in a reasonable manner. If I simply use System.out.println() as in the command line version, I see the output from my task. However, simply trying to put that same output into a TextArea using .appendText() doesn't update the TextArea until the background process completes.
I see all sorts of clippings relating to Task, CreateProcess, invokeLater, updateProgress, but none of them seem to solve their original posters' question (nor mine at this point).
I am having trouble with an array out of bounds exception. I understand what the error means (that I am trying to access part of array that does not exist). But I do not see the error in my code.

int i;

I have been doing a program that allows the user to input students names and numerical grade values. I have already completed 3/4 of the program but am stuck on the bubblesort method as this is what it requires:
The program must have an indefinite loop, which prompts the user to select a sorting criterion or to end the program, and must also use bubble sort. Note: The user may either select name or grade as the sorting criteria. The program must use bubble sort to sort that data according to the specific criteria and then use another loop to display the data. This process must continue until the user ends the program.
My problem is, while i can easily do the bubblesort, where to look on how to link elements of the two arraylists I'm using (one for grades, one for names) so that when the user decides what sort they want, the individual's name and grade stays together.
import java.io.*;

Here is the application that does this; test your coding of class PieChartWriter with it.
import java.awt.*;
public class TestPieChart

{ PieChartWriter p = new PieChartWriter();
p.setTitle("How I spend my day");
p.setSlice1("Sleep: 7 hours", 7, Color.black);
p.setSlice4("Recreation: 9 hours", 9, Color.gray);
p.setSlice2("In class: 3 hours", 3, Color.blue);
p.setSlice3("Homework: 5 hours", 5, Color.red);

I need to make a loop that prints out a certain number of asterisks, depending on the random number generated (includes 0-24, not including 25). I'm just in basic java programming and am stuck on this task.
These are the directions given to me:
Write a loop to do the following tasks 10 times:
-Generate a random number in the range of 0 to 24 and store in an int variable named: score
-Write loop to print a bar of asterisks proportional to the value in score :
For example: , if value stored in score is 8, the bar chart should like as follows: (value of score spaced by a tab ( ) and a series of 8 asterisks in one line)
8 ********
//end of the loop
I've tried looking for other questions like this, but this one is a random number, with no input. Yes, I know there are easier ways, but my professor is extremely picky with everything.
This is what I have so far:
public class PA5LoopsA {
public static void main(String [] args) {
//Declare variables
int score;
//Generate random number between 0 and 24
score = (int) (Math.random() * 25);
[Code] ....
Clearly, none of my formatting went through...yes, I know how to space everything out!
Here is the assignment instructions:
Overview: Use the Eclipse Java environment to create and test a program using methods that will display a bar graph.
Specifics: This assignment is an extension of the Module 5 activity, the first bar chart (asterisk) display program. You should also make use of the Bar Chart printing program of Chapter 6 (Fig. 6 in the textbook, p. 217).
Your program should use methods to accept input from the keyboard, store it in an array, and use that data to display a bar graph.
Pseudocode for the program might look like the following.
Main
declare an array of integers
get the number of asterisks in each bar
print the bar graph
get the number of asterisks in each bar
declare a Scanner input object
declare an array to fill and return
[code]....
Problem is I cannot get it to display the number of asterisks I enter as input.

I have a JScrollPane and JTable inside. In the right column of the table at the end (south) I made a ChartPanel in one of the classes where I make the design for the Frame:
Java Code:
ChartPanel chartpanel = new ChartPanel(pieChart);
pCapturing.add(chartpanel, BorderLayout.NORTH); mh_sh_highlight_all('java');
And when I click on any row above, from the list in the column, I would like an appropriate pie chart to be drawn.
I need here (in another class where I define the getTableCellRendererComponent) to enter a code to display the chart in the last row of the panel:
Java Code:
PieChart3 pie=sectionsChartProvider.getSectionPieChart(section);
...
...
if((hasFocus) || (isSelected)) {
if(column == 0)
setBorder( new MatteBorder(1, 1, 1, 0, colorBorder) );
[Code] .....
But, I don't know how to do this. I also have a class for drawing the pie chart.
I use JTable and JScrollpane in my java application, and I would like for every selected row in the scroll pane, the pie chart to be made for the values in % that the row contain.

I am trying to get this program to take 5 integers from a user and print a bar chart made of asterisks. The only way I've been able to access the values stored in the array is when my loops are nested, but this keeps my output from printing the way I would like it to.
