I am trying to make the plot area and chart area completely transparent (called no fill in the Excel gui). I have tried the following (for the chart area) with no success:
chart.ChartArea.Background = BackgroundMode.Transparent;
chart.ChartArea.Area.FillFormat.Pattern = FillPattern.None;
chart.ChartArea.Area.Formatting = FormattingType.None;
chart.ChartArea.Area.ForegroundColor = Color.Transparent;
chart.ChartArea.Area.BackgroundColor = Color.Transparent;
Can someone point me towards the correct property?
