Show Text values in Scatter chart [message #1111543]

Hi

I'm relatively new to Birt. I'm using BIRT to create charts in RAP. I have managed to create a scatter chart with different points depicted in the chart.

However, all the points shown in the graph are associated with unique names and I want these names to be shown in the legend. As of now, I'm able to show either series values in the legend, but not a totally new set of values/identifiers. Can anyone help with regard to this? So this is basically a set of text values.

I generate my charts programatically.

Attached is the pic of the chart I generate as of now, I need text values to show up in the legend instead of the numbers shown.
index.php/fa/16234/0/

Cheers
Prince

Have you tried using the string field as the y-series grouping field?

Thanks for your response Michael. I have not used grouping before, so I will give it a try. Meanwhile, if you have an existing example of the same, can you please provide it. That will expedite my try Smile

Appreciate your time.

I might have an example lying around somewhere, but I'll have to find it. Smile

I'll post it if I find it.

Hi Michael

I could not get the grouping thing to work, but I managed to try out chart scripting and used the beforeDrawLengendEntry() method to replace the legend items to the text values I wanted. I stored my own dataset in the one of the series, which I read from this method to achieve it.

So while this is resolved, I'm still curious to find out the grouping approach you mentioned. So if you do get a chance to find that example, please share. Thank you.
