I create my chart by inserting data points like so:
The points themselves are created thusly. I explicitly specify types for your convenience.
When I call the add method, I obtain the graph (supplied) "mychartnormal.png". I'm happy with this graph.
When I do the following manipulation of the graph, I obtain a new figure (supplied) "mychartweird.png". The number formatting of the highlighted values shows unnecessary precision.
You may wonder at this point why I am not manipulating the Definition.Appearance.Fill property of the series that I pick out on line one directly. Well, the reason being is that I want to the drawing animation to restart, and I didn't find another way in the API do that. As such I am open to two possible solutions.
Firstly there's the obvious rewrite that solves the problem, but I find it in bad taste to have to recreate the series, since I may need to modify other properties separately, and the copying on line 3 can easily become unwieldy.
Secondly all I really need is to restart the animation. I only found one relevant post, which said to use Chart.ResetTheme(), which didn't work for me.
