Dojo Forum

I am trying to develop Bar Chart and Bubble Chart using Dojo 1.0 Chart on WebSphere Portal Server 6.0 and RAD 7.0. For a simple web application this has been done, but for a portlet I am facing problems. It would be great if somone can help me on this. Here are the details of my code for trying to implement dojox.charting.Chart2D.

dojo.require("dojox.charting.Chart2D");
makeObjects = function(){
var chart1 = new dojox.charting.Chart2D("test1");
alert("chart1:" + chart1);
chart1.addAxis("x", {fixLower: "minor", fixUpper: "minor", natural: true});
chart1.addAxis("y", {vertical: true, fixLower: "major", fixUpper: "major", includeZero: true});
chart1.addPlot("default", {type: "ClusteredColumns", gap: 2});
chart1.addSeries("Series A", [1, 2, 3, 4, 5], {stroke: {color: "red"}, fill: "lightpink"});
chart1.addSeries("Series B", [5, 4, 3, 2, 1], {stroke: {color: "blue"}, fill: "lightblue"});
chart1.render();
};
dojo.addOnLoad(makeObjects);

(1) With this code what I am getting is a blank page! I tried IE, Firefox and Safari browsers.

Instead of I also tried writing this to another JSP and including it like:

(2) With I am getting a Java Script error:
'dojo' is undefined for the code dojo.require("dojox.charting.Chart2D");

I am unable to make out whether this is a dojo loading problem, or some rendering problem. It would be great if somebody can help me out.

I am facing problem implementing Chart2D with Dojo 1.0 on Websphere Portal (portlet) 6.0. I am getting a strange JavaScript error:
currentStyle is null

Strange enough, I have not used any JavaScript var called currentStyle. I am unable to understand how I am getting this error. I tried on both IE and Mozilla Firefox. On IE I am getting this JavaScript error and on Mozilla Firefox the page is blank, does not say anything!

Secondly, I have to implement a bubble chart. Does anyone have any idea how I can do this?
