I have been using your /help pages to read about how to use the various controls. Right now I'm working with the RadChart. Although there are some examples that are instructive I find a need for detail docs on the various classes and objects such as we have with MSDN.
For instance I see how to roughly use SeriesMapping because there is an example that uses it and I can create a SeriesMapping/ItemMapping object and see that intellisense has a one line description for the properties, methods, and events. But is there a discussion of the methods somewhere?
In your "Create a Data Bound Chart" section I see how you are using the seriesMapping object to setup a chart but it leaves me wondering how I would, for instance, set the X-Axis to a specific max value.
In your next example "Create a line chart with Static Data" you are using radChart.DefaultView.ChartArea.AxisX.MaxValue = 12 to accomplish this. It looks like there are two different ways in which to setup a chart: SeriesMapping and RadChart.DefaultView....
I wonder which one is best.
Although I am using examples from RadChart, this is really more a question about the documentation in general which is why I'm posting it both in general and radchart sections. Does such documentation exist or am I just missing it?
Thanks,
Gary

Hi Gary Blakely,
The best approach to populate the RadChart control is using the ItemsSource property together with series mappings. This approach enables using of zooming and scrolling, sorting, filtering, grouping and aggregation. As you can see from most of our examples we try to use that approach.
About the Axis - usually you would want to leave the default setting AutoRange=true and the axis will configure itself according to the data series you have. It will find the min and max values across all series, and choose a reasonable step. In certain cases you can turn this automatic logic off and manually set the axis min, max and step.
We understand that some of these concepts are not ideally explained for customers who are new to charts and we take your feedback seriously. We will do our best to improve our help not only with "hows" but with explanations of "why" a certain setting is more appropriate etc. etc.
Sincerely yours,

Vladimir,
Well, this thread is almost a year old and it doesn't look like you take "new to charts" seriously at all. I've not seen any documentation that describes the various controls, elements, objects used in Charts ... nothing like MSDN level of documentation ... either online or local.
If this has happened, is there any chance you can show us where this documentation exists? I can't find any for Q3 2011.
I had no problem figuring out Microsoft's Toolkit Chart and I'm sure that isn't Telerik's goal to push developers to use MS Charts rather than Telerik's?
How about some documentation that says exactly what each property does? Binding samples, etc. etc.
Like I said, this thread is a year old so I do sorta believe documentation is not important to Telerik?

Hello Rob,
During the last year our team was busy pushing out the new RadChartView control which is due to ship in Q1 2012. We have poured all our documentation resources towards the new product and we have produced a help topic which should cover you. It includes code samples and instructions on how to databind a chart.
Please take a look at it here: http://www.telerik.com/help/silverlight/radchartview-series-databinding.html
As always, we have our online demos at your disposal as well which include a source code viewer for your convenience.
I am eager to learn if this sort of documentation feels adequate and looking for feedback if and how it can be improved further.
Kind regards,
Vladimir Milev
