I am evaluating the Infragistics products for new Financial application. I am looking at both "NetAdvantage for WPF line of business" and "NetAdvantage for WPF data visualisation".
Currently nearly all of my required functionality appears to be present. There is one big feature outstanding: How can you allow users to annotate the charts?
For example, a user may indicate an area of a bar chart that refers to the 1930's. They would be able to indicate this with a shape (circle or square) or line. They would then be able to write a text description that would be shown on the chart.
Ideally we would be able to create these annotations programmatically too and, optionally, for the user to be able to interact with these programmatically created annotations.
Is this possible in either "NetAdvantage for WPF line of business" or "NetAdvantage for WPF data visualisation"? If not, can you suggest an approach to create them outside your model? My concern about creating them myself is that the zooming and panning won't work.
Alternatively, could I somehow extend the ToolTip model to make them always visible? This could be helpful.
There are annotation features on our roadmap, but they have not been added to the xamDataChart as of yet.
That being said there are many ways that you can annotate the chart in its current state. They amount to registering for various events to know when the chart's zoom level or size changes, and then using information that the chart publishes to you to render your annotations into the chart. Here are some links to implemenations of various annotation types:
Let me know if you have any questions or have different requirements that aren't covered by these and was should be able to help out.
Hope this helps!
Have this functionality from your roadmap been added? It's been almost 3.5 years now.
Currently this feature is not implemented as build in functionality, so you can check this forum thread where there are different approaches for adding annotations to the XamDataChart:
