Hello,
Can someone please help me out with displaying a series of graphs on a webpage? Essentially, what I want to do is have a webpage that clients can log into to view visual statistics of a web survey. But I can't find any information about how to do this using reporting -specifically, how to get the graphs working in a web page. Is there any tutorials on this?

The Chart report item uses the same engine as RadChart for ASP.NET AJAX, so if you are familiar with it, you should easily get on the right track. There are some differences and limitations however both from chart and report point of view:
  • as explained in the chart help article referenced above, the chart does not use the reporting data engine and therefore it can be bound only manually by using the chart's NeedDataSource event.
  • interactive features such as tooltips, maps, active regions and events inherent to the RadChart control are not supported.
Although it shares the same API as the chart web control, our suggestion is to look at the chart documentation in the report help as it is updated according to the supported features. You can also see the chart in action in two of our demo reports:
As for showing the chart in a web page - you can use the Web Report viewer to display the report you have created in your web app/site.

Cheers!

Where is the full documentation for the Graph object? or any samples/demos that we could use to learn to use this object.

Hi Wadigzon,

You can find more information about the Graph item in our online help under Designing Reports - Report Structure - Graph. In addition, we have illustrated the Graph item use in our local demos installed by default in C:\Program Files (x86)\Telerik\Reporting <version> and more precisely in the following report definitions:

I hope this helps.

Hi,
my Problem is similar. In the documation I found the Charts marked as obsolete, better use Graph. Is it possible to select a skin or theme in Graphs?
thanks

Hi Telerik,

I have some problems to bild a Chart. I have a very simple SQL-DataSource like this:
select jahr, sum(menge) as menge
from   v104_mont_jahr_monat_kw_land
where  jahr >= 2010
and    land = 'DE'
group by jahr

this is the datasource of my Chart. I defined a Serie with DataXColumn = jahr and DataYColumn = menge and DefaultLabelValue = #Y{N0}. So I followed all the examples you offer in Videos an tutorials. But the chart does not work. On preview there is always shown the error: the type of column with name menge is not numeric.

what is going wrong?
I need urgently help.
many thanks
Irmgard

Hi Irmgard,

Please take a look at the forum thread you have opened on the same question. In future please avoid double-posting or switching the main topic of the thread.

I see there is a lot of documentation on the obsolete Chart, but not so much for the Graph.  Can you point me in the direction of the full documentation for the Graph properties?  I have found this:
http://www.telerik.com/help/reporting/properties_t_telerik_reporting_graph.html

I feel like I have too many individual questions about the graph, and before I start hammering you guys with trouble tickets and forum posts, maybe you have an unpublished list of properties for the Graph.  Thanks.

Hi Ray,

Looking at the Graph's API reference itself could be boring and unavailing. That's why we created several how-to articles and conceptual topics to introduce the users to the most common tasks that can be done using the Graph item. Some of the articles involve more advanced techniques like sharing a common axis between the series and creating the Graph definition programmatically.

Please take a look at this part of documentation and in case you have more specific questions, do not hesitate to ask.

Regards,
