How To Create A PIE Chart
Jan 14, 2014Here is the application that does this; test your coding of class PieChartWriter with it.
import java.awt.*;
public class TestPieChart
{ public static void main(String[] args)
{ 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);
}

Bar Chart With Asterisks
Oct 12, 2014I 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, 2014Here 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.
Creating A Chart For Work?
Mar 6, 2015I 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.
Displaying Pie Chart In JScrollPane
Mar 12, 2014I 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.
Making Pie Chart For Values That The Row Contain
Mar 9, 2014I 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.

Print Array Asterisk Bar Chart
Jul 6, 2014I 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();

Creating Chart Of Data - SerialPorts

JavaFX 2.0 :: Horizontal Stacked Bar Chart
Sep 14, 2014Using 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));

View Replies View RelatedScheduling Software - Display Chart Showing Lesson Times For Particular Teacher And Students
Aug 27, 2014I 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?
JSF :: Styling PrimeFaces File Upload Tag
Mar 22, 2014I'm having some problems styling the PrimeFaces upload tag <p:fileUpload /> in my application.
In my xhtml code I have the following:
<p:fileUpload id="fileUpload" fileUploadListener="#{filters.upload}"
allowTypes="#{filters.uploadTypes}" invalidFileMessage="#{filters.uploadBadType}"
sizeLimit="#{filters.uploadSize}" invalidSizeMessag="#{filters.uploadBadSize}"
update="fileUpload fileTable filterTab uploadMessage hiddenNum hiddenPhoto uploadError footer
namePhotSystem checkOverwrite"
description="Select Text File" disabled="#{filters.fileuploadDisabled}" fileLimit="1"
fileLimitMessage="You are only allowed to upload one file at a time"
styleClass="fileUploadClass" label="Choose the File to Upload" auto="true" />
This all works correctly, both the AJAX update and on the server, but I'm unable to get the button or buttons displayed in the way I need.
By including the following in my CSS:
.ui-fileupload.fileUploadClass {width:428px;}
.ui-icon-plusthick {display:none;}
.ui-button-text {width:200px; height:20px;}
the first sets the width of the button bar, and by looking at the HTML code generated by PrimeFaces, I discovered that the second hides the "+" to the left of the "Choose" button, which here has been replaced by the text "Choose the File to Upload". However, this text is displayed on two lines, with the word "Upload" on the second. I want the whole text to be on one line, but no matter what I do, I cannot get this to work properly. The third line of my CSS code does indeed reduce the height of the button, but the width does not work at all, and the last part of the text is simply lost. How do I put all the text on one line and adjust the width of the button?
Another question is that when I remove the auto="true" attribute from the tag, which I had originally, the "Upload" button is displayed to the right of the "Choose" button, and when a file is chosen but not yet uploaded, it is displayed below the button. This is a capability that I might still want, however, I am unable to style the display, and in particular the progress window to the right of the file name and size. All the files I want to upload are relatively small text files, and I want to adjust this window or even hide it completely. How is this done?
Incidentally, because the files are all quite small, I have disabled the display of the "Cancel" button, so either only the "Choose" button is shown, or the "Choose" and "upload" buttons.
JSF :: Styling Primefaces Elements With CSS File
Nov 19, 2014Currently I am having difficulties styling a particular prime faces element in a JSF application for work. I'm tasked with giving the ui a styling and color scheme acceptable to our project design. However I am finding myself unable to "hook" a particular pf element with an ID so that I can proceed with styling a imported .css file.
I'm trying to style the commandLink button to display in Orange 20px font with Italic but when I inspect the element in chrome after being rendered It doesn't even show its style linked to the assigned ID. The class style for mainMenuItem is being applied to the commandlink but is immediately over written by ui-widget. I'm trying to style that one single component(override/replace ui-widget with the properties in the #loggedInUserID)
Current .XHTML code and the css file has been linked with
<h:outputStylesheet library="css" name="masterPW.css"/>
<div class="mainMenuItem"><p:commandLink id="loggedInUserId" styleClass="maserPW.css" value="#{loginController.userFullName}"/>
</div><!--End of mainMenuItem-UserID div -->
