考虑构建ASP.NET图表图像的ASP.NET MVC控制器方法。
public FileStreamResult MakeImg(IEnumerable<MyObj> stats)
{
Chart barchart = BarChart(400, 300);
Series series1 = new Series("Series1");
series1.ChartArea = "ca1";
series1.ChartType = SeriesChartType.Column;
series1.IsValueShownAsLabel = true;
series1.Font = new Font("Verdana", 9f, FontStyle.Regular);
barchart.Series.Add(series1);
// Set chart data source
barchart.DataSource = stats;
// Set series members names for the X and Y values
barchart.Series["Series1"].XValueMember = "FriendlyDate";
barchart.Series["Series1"].YValueMembers = "NumRecords";
// Data bind to the selected data source
barchart.DataBind();
MemoryStream ms = new MemoryStream();
barchart.SaveImage(ms, ChartImageFormat.Png);
ms.Seek(0, SeekOrigin.Begin);
return new FileStreamResult(ms, "image/png");
}
图像以不吸引人的方式呈现:

问题:如何以编程方式为:
设置字体答案 0 :(得分:13)
chart.ChartAreas[0].AxisX.LabelStyle.Font
chart.ChartAreas[0].AxisY.LabelStyle.Font
是设置Axes字体所需的属性。
答案 1 :(得分:1)
Chart1.ChartAreas [0] .AxisX.LabelStyle.Font = new System.Drawing.Font(“Verdana”,8f); Chart1.ChartAreas [0] .AxisY.LabelStyle.ForeColor = System.Drawing.Color.Red;
答案 2 :(得分:0)
我遇到的另一个问题是文字上的锯齿。从.png
更改为.jpg
就可以了!
