HI

我试图使用MS Chart控件创建简单的饼图。当我的饼图在浏览器中呈现时,我得到饼图周围的填充,我无法摆脱。我想饼图坐在图像的边缘没有填充或边距。关于如何实现这一目标的任何想法?

在我的代码下面,填充以蓝色突出显示。即Chart1.BackColor = System.Drawing.Color.Blue;

 <script type="text/C#" runat="server">
        protected void Page_Load(object sender, EventArgs e)
        {
            //Set the chart type
            Chart1.Series["Series1"].ChartType = SeriesChartType.Pie;

            //add points
            Chart1.Series["Series1"].Points.AddY(12);
            Chart1.Series["Series1"].Points.AddY(45);
            Chart1.Series["Series1"].Points.AddY(67);

            //set back color of chart object
            Chart1.BackColor = System.Drawing.Color.Blue;

            //set back color of chart area
            Chart1.ChartAreas["ChartArea1"].BackColor = System.Drawing.Color.Green;

        }
    </script>

    <asp:Chart ID="Chart1" runat="server">
        <Series>
            <asp:Series Name="Series1" ChartType="Pie">
            </asp:Series>
        </Series>
        <ChartAreas>
            <asp:ChartArea Name="ChartArea1">
            </asp:ChartArea>
        </ChartAreas>
    </asp:Chart>

我并不是特别熟悉饼图,但对于折线图,需要在ChartArea中设置位置:

<ChartArea Name="ChartArea1" BackColor="Transparent" BorderWidth="0" >
      <AxisX LineWidth="0" IsMarginVisible="False">
      </AxisX>
      <Position Height="100" Width="100" X="0" Y="0" />
    </ChartArea>

将图表区域设置为从左上角开始,我相信并占据图表的整个区域(100%)。然后你需要IsMarginVisible = false来阻止左边和右边的边距。希望这对你有用。
