Here I will be explaining the similar concept using JQuery. As everyone aware that JQuery is getting very famous and even Microsoft announced that JQuery will be available as part of the Visual Studio 2010 with intellisence too.
Most of the times our customers expect to develop the charts with no time for preparing lots of dashboards or metrics. Lets consider that we have a Task List with all the tasks assigned to different users and are at the different status like:
1. Not Started
2. In Progress
3. Completed
4. Deferred
5. Waiting for someone else
At this point of time we may get lots of request for building the charts for this list data. I will be concentrating on generating the Pie Chart for Different Status available in this Task List, to identify how many tasks are there at different statuses. Following is the sample image showing the List Data:
Following are the steps to implement the fusion charts:
1. Download Fusion Charts and upload to a document library. In this case I created a separate document library called FusionCharts where all the fusion charts are uploaded.
2. Come up with the RPC Protocol URL for extracting the data from the task list.
In our case following is the URL:
http://localhost/sites/MOSSDemos/_vti_bin/owssvr.dll?Cmd=Display&Query=Status&List=%7B7C6C7072%2D12B5%2D4B05%2D90A4%2D052160CC8F74%7D&XMLDATA=TRUE
Note that we are extracting only the Status field from the Task List.
And the List id is the Task List Guiid within the SharePoint Site.
3. Download JQuery script from the site and upload to the Shared Documents.
4. Copy the following javascript which uses JQuery Script into the content editor web part:
<!-- JScript from shared documents -->
<script type="text/javascript" src="/Shared Documents/jquery-1.3.2.min.js"></script>
<!-- Div tag for appending the graph -->
<div id="divGraph"></div>
<script type="text/javascript">
// Declare all local variables
var iNotStarted = 0;
var iInProgress = 0;
var iCompleted = 0;
var iDeferred = 0;
var iWaitingonsomeoneelse = 0;
var sObjectData = "";
// Call the function once the document is loaded
$(document).ready(function() {
var sSiteUrl = "http://localhost/sites/MOSSDemos/_vti_bin/owssvr.dll?";
// This Parameter Contains List Id too
var sCmdParameters = "Cmd=Display&Query=Status&List=%7B7C6C7072%2D12B5%2D4B05%2D90A4%2D052160CC8F74%7D&XMLDATA=TRUE"
// Ajax call using a JavaScript
$.ajax({
url: sSiteUrl + sCmdParameters,
type: "GET",
dataType: "xml",
data: "",
complete: processResult,
contentType: "text/xml; charset=\"utf-8\""
});
});
function processResult(xData, status) {
//alert(xData.responseXML.xml);
var NS = '#RowsetSchema'
$(xData.responseXML).children(1).children(1).children().each(function() {
var Status = $(this).attr("ows_Status");
switch (Status) {
case "Not Started":
iNotStarted = iNotStarted + 1; break;
case "In Progress":
iInProgress = iInProgress + 1; break;
case "Completed":
iCompleted = iCompleted + 1; break;
case "Deferred":
iDeferred = iDeferred + 1; break;
case "Waiting on someone else":
iWaitingonsomeoneelse = iWaitingonsomeoneelse + 1; break;
default:
break;
}
});
// Create the Object for the Fusion Chart
// Opening Object Tag
sObjectData = "<object classid=\"clsid:D27CDB6E-AE6D-11cf-96B8-444553540000\" ";
sObjectData += "codebase=\"http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0\" ";
sObjectData += "width=\"400\" ";
sObjectData += "height=\"300\" ";
sObjectData += "id=\"Pie3D\"> ";
// Setting Parameters
sObjectData += "<param name=\"movie\" value=\"http://localhost/sites/MOSSDemos/FusionCharts/FusionCharts/FCF_Pie3D.swf?chartWidth=400&chartHeight=300\"> ";
sObjectData += "<param name=\"FlashVars\" value=\"&dataXML=<graph caption='Tasks By Status Percentage' ";
sObjectData += "xAxisName='Site' yAxisName='Qty by Site' showNames='1' decimalPrecision='1' showPercentageInLabel='1' formatNumberScale='0' ";
sObjectData += "pieYScale='70' pieBorderAlpha='40' pieFillAlpha='80' pieSliceDepth='15'> ";
sObjectData += "<set name='Not Started' value='" + iNotStarted + "' color='#660033' link='' /> ";
sObjectData += "<set name='Completed' value='" + iInProgress + "' color='#3399ff' link='' /> ";
sObjectData += "<set name='In Progress' value='" + iCompleted + "' color='#99cc99' link='' /> ";
sObjectData += "<set name='Deferred' value='" + iDeferred + "' color='#00ff99' link='' /> ";
sObjectData += "<set name='Waiting for someone else' value='" + iWaitingonsomeoneelse + "' color='#000033' link='' /> ";
sObjectData += "</graph>\"> ";
sObjectData += "<param name=\"quality\" value=\"high\"> ";
sObjectData += "</object> ";
$("#divGraph").append(sObjectData);
}
</script>
Following are the lines to be changed in the script:
A. Location of the FCF_Pie3D.swf file within the "object" tag.
B. Site Url in the variable "sSiteUrl".
C. Task List Id in the variable "sCmdParameters".
D. Path of the JScript (Assumed it is available in the Shared Documents)
With this, A Pie chart representations the Task Data within the SharePoint List as shown below:
