Custom Charting

Hey can I write my own charting component for Reporting Services? Where
could I find information on that?
Thanks,
CJHello CJ,
Generally the answer you'll get to that question is "no" you cannot create
your own charting component for Reporting Services.
What you can't do easily is create a new custom component that you can host
in a Report and in the Report Designer.
However if you are prepared to make some compromises you most certainly can
create a custom component that takes your data and generates an image stream
that is displayed in a Reporting Services Image control.
This is usually best done by creating a custom data processing extension,
and ensuring that one field is an image stream of the data, but if you think
carfully about how to get all the data your component requires parsed into a
DataSet field then you can do this entirely in a function within a custom
assembly. What you do there is pass in the DataSet field containing your
parsed data, and have the Function work with this data and return an image
stream.
ok - so that is indeed only going to return a static image of your
component, but depending on what you are trying to do, you may be able to
programmatically set the Jump to URL Action property of the image control
containing the image of your component to jump to a URL in which you might
have a more fully functional and interactive version of the component.
I think future versions of Reporting Services would be missing a trick if
they don't provide a straightforward mechanism for hosting custom components
within reports, although there are doubtless architechural issues that the
developers will have to work out.
