I attemtping to use Charts in MVC 3 and asside from the default ChartThemes provided it seems way harder to specify themes. There is no longer a way to edit ChartAreas or access many strongly typed properties (the argument type for chart area is just a string).
Previously you could do something like this:
Old Way
ChartArea area = new ChartArea {
BackColor = Color.Transparent,
AxisX = new Axis {
Interval = 7,
IntervalType = DateTimeIntervalType.Days,
IsMarginVisible = false,
LabelStyle = new LabelStyle { ForeColor = Color.FromArgb(255, 128, 128, 128), Font = new Font("Arial", 10, FontStyle.Regular), Format = "MMM dd" },
LineColor = Color.FromArgb(255, 208, 208, 208),
MajorGrid = new Grid { LineColor = Color.FromArgb(255, 242, 242, 242), LineDashStyle = ChartDashStyle.Solid },
MajorTickMark = new TickMark { LineColor = Color.Transparent, Size = 4.8f }
},
AxisY = new Axis {
IntervalAutoMode = IntervalAutoMode.VariableCount,
LabelStyle = new LabelStyle { ForeColor = Color.FromArgb(255, 128, 128, 128), Font = new Font("Arial", 10, FontStyle.Regular) },
LineColor = Color.Transparent,
MajorGrid = new Grid { LineColor = Color.FromArgb(255, 242, 242, 242), LineDashStyle = ChartDashStyle.Solid },
MajorTickMark = new TickMark { LineColor = Color.Transparent, Size = 0.8f }
},
Position = new ElementPosition { Height = 90, Width = 99, X = 0, Y = 10 }
};
New Way
Chart chart = new Chart(width: 400, height: 200, theme: ChartTheme.Yellow)
.AddSeries(
chartType: "line",
xValue: dates.ToArray(),
yValues: data.ToArray(),
chartArea: someString)
The chart area data is now just a string and you have chart themes are a string and there are a few defaults.
This seems like a massive step backwards? Am I missing something fundamental?

I think you'll find the the default themes are just that. You still have the ability to override styling by substituting your own chartarea xml. Take a look here at the ChartTheme reference

I agree the Charts helpers is very basic. Dundas charts provided a better way of doing things.
Microsoft acquired Dundas Data Visualization Intellectual Property in April 2007 and is integrating this technology in different Microsoft products since then.
These still sends images a better alternative is HighCharts which is build on javascript.

No, the chart helper is pretty weak. But you can still do it the old way using the Data Vizualization package. Of course, that package is extremely poorly documented. Here's something to help get you started at least.
