如何在全屏显示图表图像？

Question

图表生成得太小了。我正在使用asp.net图表控件。如何显示图表图像大小而不进行缩放。如何根据asp.net中的数据使图表高度和宽度动态变化？

It depends on how you are using it exactly, but System.Web.UI.DataVisualization.Charting.Chart has a Width and a Height property:

System.Web.UI.DataVisualization.Charting.Chart Chart1 = new System.Web.UI.DataVisualization.Charting.Chart();
Chart1.Width = 412;
Chart1.Height = 296;
Chart1.RenderType = RenderType.ImageTag;
//....
// Render chart control
Chart1.Page = this;
HtmlTextWriter writer = new HtmlTextWriter(Page.Response.Output);
Chart1.RenderControl(writer);

or

<asp:chart id="Chart1" runat="server" Height="296px" Width="412px" ImageLocation="~/TempImages/ChartPic_#SEQ(300,3)" Palette="BrightPastel" imagetype="Png" BorderDashStyle="Solid" ...
