When I work with users and business managers, there’s one thing they always appreciate: time-saving features, especially those with graphics. My users love them and yours will too. By viewing current graphic data displays, users can instantly see if things are going well or not without waiting for reports or evaluating and crunching numbers manually. In case you did not know, the Google Chart API lets you dynamically generate charts in SharePoint. That’s right—DYNAMICALLY! It’s easy to integrate Google Chart using SharePoint List data. All you need is graph criteria. In this case, I use a Group By view on a list column.
In this article, I’ll show you how to use Google Chart API in SharePoint 2007 (MOSS):
2. Create a Web Part page (used to display graphical representation of the list data)
3. Integrate Google Chart API into SharePoint
The Projects custom list is created.
5. Click Settings > Create Column.
• End Date (Date)
• Status (Choice list: Complete, Deferred, In Progress, Not Started)
To create sample data, click New.
7. Fill the New Item form, and click OK.
8. Repeat until you have enough data to demonstrate your Google Chart API.
For this example, I created 10 items.
• Accept defaults
4. Click Create.
INTEGRATE GOOGLE CHART API INTO SHAREPOINT
To display the graphical representation of any list data, we first need to decide which column of the list we want to use as a graph criteria. Then we need to create a “grouped by” list view on that column. For chart to be displayed, the “grouped by” list view must be on the same page.
I use Status as the criteria for the graph. We first need to add the Projects list web part on the Sample Page to display Projects list “group by” Status column.
1. Click Add a Web Part in any of the zone of the page.
3. Click Add.
4. Click Edit > Modify Shared Web Part.
5. Click Edit the current view link.
8. Select your preference for Ascending or Descending order.
9. Click OK.
The newly created list view will be added on the Sample Page.
Now to add graph for the list view, we need to add another web part on the Sample Page: Content Editor Web Part
13. click Add.
14. Select Edit > Modify Shared Web Part.
16. Copy the following code and paste into the Text Entry dialog box:
<div id="jLoadMe" class="content"><strong>Project Status - Pie Chart Using Google Charting API</strong></div> <script type="text/javascript">if(typeof jQuery=="undefined"){ var jQPath="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/"; document.write("<script src='",jQPath,"jquery.js' type='text/javascript'><\/script>");} </script> <script type="text/javascript"> $("document").ready(function(){ var arrayList=$("td.ms-gb:contains(':')"); var coord= new Array(); var labels= new Array(); $.each(arrayList, function(i,e) { var MyIf= $(e).text(); var txt= MyIf.substring(MyIf.indexOf('(')+1,MyIf.length-1); // Extract the 'Y' coordinates coord[i]=txt; var txt1= MyIf.substring(MyIf.indexOf(':')+2,MyIf.indexOf("(")-1); // Extract the labels labels[i]=txt1+"("+txt+")"; //add also coordinates for better read }); var txt= coord.join(","); var txt1= labels.join("|"); // Adjust Chart Properties below - See Google Charts API for reference var vinc= "<IMG src='http://chart.apis.google.com/chart?cht=p3&chs=750x200&chd=t:"+txt+"&chl="+txt1+"'/>"; $("#jLoadMe").append("<p>"+vinc+"</p>") });</script>
17. Click Save.
You will see that the graph has been added into the web part.
18. Click OK. If you see the Security Warning box as below, click No.
