Creating Chart Of Data - SerialPorts

Apr 10, 2015

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.

[URL] ....

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.

Creating A Chart For Work?

Mar 6, 2015

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.

Oct 10, 2014

i need to create an array with attributes name, gender, phone, age.and then sort acording to age in ascending order.

i created like this,

public class Array{
private String[] name={"ram", "katy", "priti", "john"};
private String[] gender={"male","female","female","male"};
private int[] phone={989898089,89898989,8982989089,898908989};

Creating Table Model For Data From Database

Sep 9, 2014

I'd like to create my own Table Model to handle data from an SQLite database using JSwing, but I'm having difficulty. How to confirm the following:

-- A table model is an object that contains methods for manipulating data in the table, right?

If that's the case, then how should I create a Table Model to handle data coming from a database. From what I understand...

My custom Table Model needs to subclass AbstractTableModelI then override 3 methods from AbstractTableModel (getRowCount(), getColumnCount(), getValueAt())

As it relates to drawing data from a database, how should I be thinking about this problem (i.e. creating a Table Model that can work with a database)?

Creating New Data Type VeryLargeInteger With / Without Premade Java Classes

Jan 22, 2014

What I'm doing about it: googling the shit out of my problems, consulting you fine readers, consulting my friends, and yesterday I signed up for Lynda.com. I'm hoping 30hrs+ or so of watching, rewatching, and analyzing the example code will catch me up before I get too behind in CS302

** Assignment Prompt **

Integer types are very convenient, but their limited width and precision makes them unsuitable for some applications where precision is more important than speed. Develop a class VeryLargeInteger that can handle arbitrary long integer numbers (both negative and positive) and the basic arith- metic operations (addition, subtraction, multiplication, division, and remainder).

Hint: The number could be represented as string, the sign could be represented either as boolean or as part of the string.

Note: Implementations of addition/subtraction through repeated use of a constant incremen- t/decrement will not be accepted. Implementations of multiplication and division that rely only on addition and subtraction will not be accepted.

I know I'm going to have to create a separate tester to call on the VeryLargeInteger class and it's math methods. For the new data type, should I convert the integer/string into an array in order to handle the large length of the number? I know he wants us to use recursion for the math methods. My gut tells me addition and subtraction will be slightly easier than multiplication and division. I know I'll have to reference the other methods for division. We aren't allowed to use the BigInteger class.

How I should construct any of the methods.

Java Code:

import java.util.ArrayList;
/**
∗ VeryLargeInteger (VLI) is a class for arbitrary precision integer computation
*/
public class VeryLargeInteger {
private int[] num1;
private int[] num2;
private int[] num3;

[code]....

Bar Chart With Asterisks

Oct 12, 2014

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!

Bar Chart With Asterisks?

Oct 19, 2014

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.

Displaying Pie Chart In JScrollPane

Mar 12, 2014

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.

Print Array Asterisk Bar Chart

Jul 6, 2014

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.

It prints:
Enter a number:
2
**
Enter a number...and so on

I want it to take the values say(2,3,5,8,4) and do this:
**
***
*****
********
****

public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner in = new Scanner(System.in);
int[] barArray = new int[5];
for(int i =0; i < barArray.length; i++){
System.out.println("Enter a number: ");
barArray[i] = in.nextInt();
for(int j = 0; j < barArray[i]; j++){
System.out.print("* ");
}System.out.println("");
in.close();
}

JavaFX 2.0 :: Horizontal Stacked Bar Chart

Sep 14, 2014

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));

You may assume that all values are positive. First figure out the maximum value. That value's bar should be drawn with 40 asterisks. Shorter bars should use proportionally fewer asterisks.

import java.util.Scanner;
import java.util.ArrayList;
import java.util.Arrays;
public class Array717
{
public static void main( String[] args )

The problem is that all this code does is print 1 line of *'s and what seems to be thousands of them

Scheduling Software - Display Chart Showing Lesson Times For Particular Teacher And Students

Aug 27, 2014

I want to develop a dynamic scheduling application that I hope to use at work, but I have some questions about the design approach since this is my first undertaking of this kind of project.

The purpose of the application is to display a chart showing the lesson times for a particular teacher and her students.

Here's are more important details:

-The chart displays the current day's schedule.
-The top row displays the teacher's name. There are at least 4 teachers each day.
-The leftmost column shows the times (from 3:00 to 8:00).
-The table is filled with the names of the students.

My current problem is deciding on the best approach to storing this data containing the teacher and her students and times. I should also note that there are about 500 students and around 20 teachers (i.e. the dataset is small). Is this a problem solved using a database and JDBC or could I just write the data to file? Are there other approaches that would solve this problem?
