Answer 1

I am not sure whether this is the best way to do it but its a workaround for now. Try this code and set the attributes of the chart manually.

            Chart chart2 = new Chart();
            chart2.ChartAreas.Add(Chart1.ChartAreas["ChartArea1"]);
            foreach (Series series in Chart1.Series)
            {
                chart2.Series.Add(series);
            }
            foreach (Series series in chart2.Series)
            {
                series.Points.Clear();
                //Add new points manually.
            }
            chart2.Titles.Add(Chart1.Titles["Title1"]);
            chart2.Legends.Add(Chart1.Legends["Default"]);
            chart2.Series["Series1"].ShadowColor = Chart1.Series["Series1"].ShadowColor;
            chart2.Series["Series1"].ShadowOffset = Chart1.Series["Series1"].ShadowOffset;
            chart2.Palette = Chart1.Palette;
            chart2.BackColor = Chart1.BackColor;
            chart2.BackHatchStyle = Chart1.BackHatchStyle;
            chart2.BackGradientStyle = Chart1.BackGradientStyle;
            chart2.BorderlineDashStyle = Chart1.BorderlineDashStyle;
            chart2.BorderlineWidth = Chart1.BorderlineWidth;
            chart2.BorderlineColor = Chart1.BorderlineColor;
            chart2.BorderSkin = Chart1.BorderSkin;
            chart2.Width = Chart1.Width;
            chart2.Height = Chart1.Height;
            Form1.Controls.Add(chart2);

Hope this helps,

There is a chart serializer that lets you save the appearence (as well as other aspects) of a chart as a file, using something like this

aChart.Serializer.Content = SerializationContents.Appearance;
FileStream output = new FileStream(fileName , FileMode.OpenOrCreate , FileAccess.Write);
aChart.Serializer.Save(output);
output.Close();

You can then apply it to another chart,

FileStream input = new FileStream(fileName , FileMode.Open , FileAccess.Read);
aChart.LoadTemplate(input);

If you are just interested in the colours there is also the Palette feature,

cChart.Palette = ChartColorPalette.Excel;
