I think there are some problems with the latest builds. I will try to fix this soon!
I think this is the same problem as reported in issue #175, not solved yet...
In ScatterSeries<T>, I suggest renaming the current ActualPoints to e.g. ActualPointsList and create a new ActualPoints property:
        /// <summary>
        /// Gets the actual points.
        /// </summary>
        /// <value>
        /// A read-only list of points.
        /// </value>
        public System.Collections.ObjectModel.ReadOnlyCollection<T> ActualPoints
        {
            get
            {
                return new System.Collections.ObjectModel.ReadOnlyCollection<T>(this.ActualPointsList);
            }
        }

        /// <summary>
        /// Gets the list of points that should be rendered.
        /// </summary>
        /// <value>A list of <see cref="DataPoint" />.</value>
        protected List<T> ActualPointsList
        {
            get
            {
                return this.ItemsSource != null ? this.ItemsSourcePoints : this.points;
            }
        }
Will this work?
I think the Angle property is currently not being used by the AngleAxis. See issue #137. I will add some comments on how to implement it!
I think this can be solved by changing the protected ActualPoints property to public. But this property should really only be exposed as a readonly collection or an IEnumerable<T>... The current implementation is a List<T> for performance reasons. Should we add another property or method that returns the actual points as IEnumerable<T>?
That issue should be reported to userecho. I fixed your post, Sir :-)
cool, I will check this one out too!
that sounds great! I will have a look at it as soon as I get a chance! sorry it is taking such a long time, I have too many things on my todo list :)
