Complete An Application Drawing Of Graphs Or Bar Charts?
Oct 27, 2009
I'm trying to complete an application drawing of graphs or bar charts
I'm attempting to write a script that reads five numbers between 1 and 30.
For each number read, output XHTML text that displays a line containing that number of adjacent asterisks.
This is code I've come up with so far.
<?xml version = "1.0"encoding = "utf-8"?>
<!DOCTYPE html PUBLIC "-w3cDTD XHTML 1.0 StrictEN"
"http:www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns = "http:www.w3.org/1999/xhtml">
[Code].....

I am needing to create a "dashboard" of charts and graphs and have been looking around at all the many different plugins that can handle that. I am wanting to stay away from flash. What is your favorite to use for charts and graphs?

I am working on an application where the user is able to draw using square images placed using absolute positions. The user can draw any shape but it must always be connected. I now need to work out the outline of the shape they created. The only information I have is the x y of the pictures that were placed. Its driving me crazy... I tried to work out a system of looping through all the pictures and seeing if there were any images touching.
My most recent idea was to make the javascript select the images and see if I could get the coordinates of the shape from there... In simple I need a way of merging the images into a shape rather than separate entities.

I've created a wizzy Javascript function embedded within PL/SQL that generates html bar charts. I would like to know if it is possible to get the javascript function to write another javascript function (embedded in PL/SQL) so I can do mouseover and display the values?

I want to create a horizontal stacked bar chart that it will support zoom in/out and mouse over events. I also want some times instead of colors to be able to use patterns. For the first part it seems that only dojo can produce those charts. In addition, i haven't seen any javascript library to support patterns in any kind of chart.

i need something simple without much overhead to read plain text (tab separated, columns & rows of data) .. and with the data i need to generate some charts (plot, bar, etc) better be interactive
since javascript doesn't need webserver like php .... setup is simple .. and can be run on any OS. i think it is my best candidate.
i dont know if javascript has any package to do stuff like this. what about interactive graph/chart? is it possible?

I'm a complete rooking at javascript (and haven't looked at php in months), but am wondering if its possible to do the following with javascript. I have a listing of 10 to 16 teams. I'd like to be able to list the teams in a drop down select box. And when the user selects a team, that teams listing of players is than shown below. The user should than be able to toggle through the listing to review each time.

I heard or read that the next version of HTML will provide long-overdue drawing commands.
Which version of Firefox, Opera or IE supports such new fancy stuff?

I need to use javascript's graphics API to draw the letters of
the alphabet. If necessary, I can map out all 26 letters myself
and use drawline() to draw them, but I am hoping someone out
there might have a better suggestion. The user will click a spot
on the canvas, and the script will draw one of the letters at
that spot.

Is there a small graphics library that I can use? All I need to do is
draw a line of a nominated thickness and colour between two specified
points and to, at some later time, "delete" the line?
I've found a few offerings but either they weren't multi-browser
compatible or they were too big for me to consider (20K instead of 2 or 3K).

jqPlot is an open source plotting plugin for jQuery. The 0.6.2 release adds many new features including:
Rotated axis text. Vertical and horizontal bar charts. Automatic trend line computation. Data point highlighting. Cursor tooltips showing data and grid position. And many other features.
The jqPlot homepage is at [url]

I am trying to create an Asteroids type game using JavaScript along with html5's canvas element for drawing. I have searched around and have looked at examples but I can't figure out what is wrong with my rendering that I do in the game loop that is run every frame. The problem appears to be only that the canvas is not cleared at the beginning of each frame but I feel there might be something wrong also. The code used and shown below only works in Firefox but not Google Chrome or Safari.

We currently have a website that uses the .beforeAfter plugin to switch between two images. In addition we would like to add the possibility to draw a line and/or box using a boxer like option. All our attempts have been unsuccessful so far.
Could anyone tell us if and how it is possible to combine the .beforeAfter option with a drawing line/box one?
For curious users, here is the website we are currently working on:

I've coded in Java before but I'm still having some trouble. I am trying to draw a ribbon type shape on an <canvas> element and for some reason, when I turned it into a function, it seemed not to work. Here is what I have for drawing the ribbon with a function:
function drawRibbon(height,width,Canvas){
var c=document.getElementById(Canvas);
var cxt=c.getContext("2d");
cxt.fillStyle="#bb0044";
cxt.beginPath();
cxt.moveTo(0,0);
cxt.lineTo(0,height-50);
cxt.lineTo((width-20)/2,height-100);
cxt.lineTo((width-20),height-50);
cxt.lineTo(width-20,0);
cxt.shadowOffsetX = 5;
cxt.shadowOffsetY = 10;
cxt.shadowBlur=10;
cxt.shadowColor = "black";
cxt.fill();
cxt.shadowOffsetX = 0;
cxt.shadowOffsetY = 0;
cxt.shadowBlur=0;
cxt.closePath();
cxt.beginPath();
cxt.strokeStyle = "#ffcc22";
for (i=5;i <= 135; i=i+15){
cxt.moveTo(5,i);
cxt.lineTo(5,i+5);
cxt.stroke();
}}
drawRibbon(200,120,navCanvas);
I feel like it has something either to do with the function definition, or the call. Before this script is executed, i create a canvas in the following way:
<canvas id="navCanvas" height="200" width="120">
Why it is not displaying.

I adapted Bresenham line drawing algorithm to draw a dashed line. I want to count the number of dashes. The dashes extend from one city on a map to another city. I don't want the dashes to obscure the city marker which is a small black dot, so I added some logic to skip dashes at the start of the line and at the end of the line. But this logic is confounding my attempt to count the dashes and I haven't been able to figure out why. The function should return the number of dashes as 'count'.
