Hi hardik,

It might be too late to change the series after the chart is already rendered and in the browser. There are a couple of options... One is to use Legend Interactivity and on MouseClick, toggle the series visibility.

Another alternative is to select hyperlink as the Interactivity option and run the report again passing a parameter that decides which series to use for the chart.

thanks in advance!

Hi hardik,<br />
<br />
There is a great article on BIRT Report Interactivity available at:<br />
<a class='bbc_url' href='http://www.birt-exchange.com/modules/wfdownloads/singlefile.php?cid=2&lid=40'>http://www.birt-exchange.com/modules/wfdownloads/singlefile.php?cid=2&lid=40</a><br />
<br />
There are several examples and screenshots to get you started.<br />
<br />
I've also enclosed a simple example that hides a series when that series is clicked on from the legend.<br />
<br />
This examples uses BIRT 2.2. To see some of the Interactivity features, like visibility, you have to enable SVG charts. Do this in Eclipse IDE at Window | Preferences | Report Design | Preview... and make sure Enable SVG Chart is selected... then run the report in the browser or Web Viewer. Your browser must have an SVG plugin to see the SVG chart correctly.

When you select Enable SVG Chart, the chart will be created in SVG..so if you can't view SVG, you wont see anything. Disabling that creates the chart as an image which is why you can see it under this circumstance. <br />
<br />
I'm using Firefox and can see the SVG chart without installing any plug-ins. For other browsers, you may need an SVG Viewer. You can get one from Adobe at <br />

I had the same issue, tried to enable toggle visibility, changed the chart foramt to SVG. but as I tried to render it in browser. The returned format is png.

Do I need to change anything else?

Thanks
Farid

I meant the char is rendered in png instead of svg.

Hi faridadham,

The only other change is in Window | Preferences | Report Design | Preview. You have to make sure 'Enable SVG Chart' is selected then run the report in the browser or Web Viewer. Your browser must have an SVG plugin to see the SVG chart correctly, otherwise you see a red X.
