ASP.NET MVC 3 MSChart Error: Only 1 Y values can be set for this data series

Question

I\'m attempting to build a stock chart using Microsoft\'s charting library.

I\'m using this code to create the chart in my view:

@{
    System.Web.H         


        

Answer 1

I was able to work around this issue by building the chart myself, bypassing the helper.

using (Chart chart = new Chart())
{
    chart.Width = 600;
    chart.Height = 400;
    chart.RenderType = RenderType.BinaryStreaming;
    chart.Palette = ChartColorPalette.Bright;

    chart.ChartAreas.Add("Top");
    chart.ChartAreas.Add("Bottom");

    chart.Series.Add("Price");
    chart.Series.Add("Volume");

    chart.Series["Price"].ChartArea = "Top";
    chart.Series["Volume"].ChartArea = "Bottom";

    chart.Series["Price"].ChartType = SeriesChartType.Stock;
    chart.Series["Volume"].ChartType = SeriesChartType.Column;

    for (int x = 0; x < data.Quotes.Count / 2; x++)
    {
        Quote quote = data.Quotes[x];

        chart.Series["Price"].Points.AddXY(quote.Date, quote.Open, quote.High, quote.Low, quote.Close);
        chart.Series["Volume"].Points.AddXY(quote.Date, quote.Volume);
    }

    using (MemoryStream memStream = new MemoryStream())
    {
        chart.SaveImage(memStream, ChartImageFormat.Jpeg);

        return File(memStream.ToArray(), "image/jpeg");
    }
}

This code is in my controller, and no view exists for it, because it is returning an actual image resource.
