Ajax and XML, and Nested Axis Feature Questions

[User (Legacy)]

I've been using your ChartFX Product for over 5 years now, and I'm very 

excitied about the possibilities that I see in the 2005 release, but in 

order to help me convince my clients to make the jump, I have  few 

questions.

1) Utilizing the New Ajax DHTML display method, will I be able to "Catch" on 

the server display changes that the user makes on the client, so that I may 

be able to persist these changes to database (The application in question 

allows users to save custome reports - and the lack of this feature in the 

ActiveX control has always been a topic of complaints amoung the user base).

2) Can a Chart be Completely rendered from an XML definition? Internal to 

this application, all the information regarding a chart is stored in xml 

(both visual attributes, as well as data). With ChartFX 2005 can a Single 

XML data structure be utilized to render the desired chart? if so, where can 

I find the schema information.

3) In many of our charts we utilize mulitple "Nested" X-Axis. In 

ChartFX.Net - This has to be kuldged together by looping theough the 

inner-most data groups, and adding the secondary and tertiary X-Axis with 

what amounts to a colspan type feature - This method works well enough 

(though is far from graceful) but fails to render anything but the innermost 

Group in the header of the "Data Table" view - forcing us to render our own 

data-tables in HTML, and negating some of the cooler UI features of the 

Client Control (Mouseover Highlights). Does ChartFX 2005 Address this issue 

at all?

Thanks for great products!

Yes. You can capture the InternalCommand event in the server to be able to 

save the chart, also Server-Side personalization features are available when 

using the DHTML renderer, check the docs on "End User Experience - 

Personalization" for more information.

Chart FX can export/import chart properties to/from a proprietary XML 

format,  Data is not included in this format.

Chart FX can read data from a different proprietary format, this is a 

different format.

There is no ONE format that includes both properties and data, for this you 

will have to implement your own.

Information about these formats can be found in the documentation at 

"Passing Data - Passing Data Using XML".

Nothing new in ChartFX 7.0 here except for the object model (for the 

attributes XML).

I´m afraid not. There is no added support for multi-level data in the 

datagrid. I would be very interested in knowing the details of your 

requirements, we are already working on a new version and if I feel the 

feature is compelling I will propose it for inclusion.

Thank you, it´s being a pleasure developing them.
