You have plenty of converters in your package... but no DateTimeToDoubleConverter??

Even though this is essential for your charts because it uses doubles for the date axis?

Turns out that binding the axis min/max/step values dont work anyway (they should)... perhaps thats there is no converter...

Also I like the way that no data is displayed unless you specify a step... good way to make ur product hard to use.

Hello Schneider,

Onto your questions:
  • We have added your feature request for DateTimeToDoubleConverter in our public issue tracking system and we will forward it to our developers for further consideration.
  • You cannot bind the Axis.MinValue / MaxValue / Step properties as ChartArea.AxisX / ChartArea.AxisY properties do not expose the actual visual axis elements (i.e. these are "data" axes and are DependencyObjects and not FrameworkElements). In Silverlight 3 the binding target can be a DependencyProperty of a FrameworkElement only (not a generic DependencyObject) and this limitation cannot be worked around. We will consider improving this behavior for the Silverlight 4 version of the control as the new version of the Silverlight framework should loosen up this restriction.
  • Indeed you are right -- this behavior was not intuitive and is already fixed (default step value equals 1 now). You can download the weekly internal build from your Client.Net account and you will be able to use the updated version of the control.


Kind regards,
Freddie
