Question

嗨，我正在做一个图表，需要放大并观察不同的距离并在上下班

不是放置缩放参数

从数据库中获取数据，但这是我完成项目所需的最后一部分

asp.net

    <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Grafica.aspx.cs" Inherits="GraficaPrueba.Grafica" %>

<!DOCTYPE html>

           <asp:Literal id="chrtMyChart" runat="server"></asp:Literal>
        </div>
     </form>

以及从中获取的数据 -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- ------------------------------.................... .................................................. .................................................. .......................

            chrtMyChart.Text = chart.ToHtmlString(); // Let's visualize the chart into the webform.

        }



    }
}
