问题描述

  private void DrawFractionChart(Excel.Worksheet activeSheet,Excel.ChartObjects xlCharts ,Excel.Range xRange,Excel.Range yRange)
{
Excel.ChartObject myChart =(Excel.ChartObject)xlCharts.Add(200,500,200,100);
Excel.Chart chartPage = myChart.Chart;

Excel.SeriesCollection seriesCollection = chartPage.SeriesCollection();
Excel.Series series1 = seriesCollection.NewSeries();
series1.XValues = activeSheet.Range [E1,E3];
series1.Values = activeSheet.Range [F1,F3];

chartPage.ApplyDataLabels(Excel.XlDataLabelsType.xlDataLabelsShowPercent,true,true,false,true,true,true,true);
chartPage.ChartType = Excel.XlChartType.xlDoughnut;

Excel.Axis轴= chartPage.Axes(Excel.XlAxisType.xlValue,Microsoft.Office.Interop.Excel.XlAxisGroup.xlPrimary)为Excel.Axis;
}

我不知道如何打开数据标签。我到处都是googled,但是迄今为止,还没有任何帮助。

解决方案

尝试这个( TRIED AND TESTED

  private void DrawFractionChart(Excel.Worksheet activeSheet,Excel.ChartObjects xlCharts,Excel.Range xRange,Excel.Range yRange)
{
Excel.ChartObject myChart =(Excel.ChartObject)xlCharts.Add(200,500,200,100);
Excel.Chart chartPage = myChart.Chart;

Excel.SeriesCollection seriesCollection = chartPage.SeriesCollection();
Excel.Series series1 = seriesCollection.NewSeries();
series1.XValues = activeSheet.Range [E1,E3];
series1.Values = activeSheet.Range [F1,F3];

chartPage.ChartType = Excel.XlChartType.xlDoughnut;

Excel.Axis轴= chartPage.Axes(Excel.XlAxisType.xlValue,Microsoft.Office.Interop.Excel.XlAxisGroup.xlPrimary)为Excel.Axis;

series1.ApplyDataLabels(Excel.XlDataLabelsType.xlDataLabelsShowPercent,true,true,false,true,true,true,true);
}

一个快速的问题。如果您不使用 xRange yRange 那么为什么要声明?



这是经过测试的完整代码。

  using System; 
使用System.Collections.Generic;
使用System.ComponentModel;
使用System.Data;
使用System.Drawing;
使用System.Linq;
使用System.Text;
使用System.Windows.Forms;
使用Excel = Microsoft.Office.Interop.Excel;

命名空间WindowsFormsApplication1
{
public partial class Form1:Form
{
public Form1()
{
InitializeComponent() ;
}

private void button1_Click(object sender,EventArgs e)
{
Microsoft.Office.Interop.Excel.Application xlexcel;
Microsoft.Office.Interop.Excel.Workbook xlWorkBook;
Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet;

object misValue = System.Reflection.Missing.Value;
xlexcel = new Excel.Application();

xlexcel.Visible = true;
//添加一个工作簿
xlWorkBook = xlexcel.Workbooks.Add();

//将Sheet 1作为要使用的工作表
xlWorkSheet =(Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

xlWorkSheet.Cells [1,5] =苹果;
xlWorkSheet.Cells [2,5] =Oranges;
xlWorkSheet.Cells [3,5] =梨;

xlWorkSheet.Cells [1,6] =80;
xlWorkSheet.Cells [2,6] =65;
xlWorkSheet.Cells [3,6] =45;

Excel.ChartObjects myCharts =(Excel.ChartObjects)xlWorkSheet.ChartObjects(Type.Missing);

//指定的xlWorkSheet.Cells [3,6],xlWorkSheet.Cells [3,6]只是为了它。
DrawFractionChart(xlWorkSheet,myCharts,xlWorkSheet.Cells [3,6],xlWorkSheet.Cells [3,6]);

//完成关闭并退出Excel
//xlWorkBook.Close(true,misValue,misValue);
//xlexcel.Quit();

// releaseObject(xlWorkSheet);
// releaseObject(xlWorkBook);
// releaseObject(xlexcel);
}

private void DrawFractionChart(Excel.Worksheet activeSheet,Excel.ChartObjects xlCharts,Excel.Range xRange,Excel.Range yRange)
{
Excel.ChartObject myChart =(Excel.ChartObject)xlCharts.Add(200,500,200,100);
Excel.Chart chartPage = myChart.Chart;

Excel.SeriesCollection seriesCollection = chartPage.SeriesCollection();
Excel.Series series1 = seriesCollection.NewSeries();
series1.XValues = activeSheet.Range [E1,E3];
series1.Values = activeSheet.Range [F1,F3];

chartPage.ChartType = Excel.XlChartType.xlDoughnut;

Excel.Axis轴= chartPage.Axes(Excel.XlAxisType.xlValue,Microsoft.Office.Interop.Excel.XlAxisGroup.xlPrimary)为Excel.Axis;

series1.ApplyDataLabels(Excel.XlDataLabelsType.xlDataLabelsShowPercent,true,true,false,true,true,true,true);
}

I am drawing a pie chart with some data:

private void DrawFractionChart(Excel.Worksheet activeSheet, Excel.ChartObjects xlCharts, Excel.Range xRange, Excel.Range yRange)
{
        Excel.ChartObject myChart = (Excel.ChartObject)xlCharts.Add(200, 500, 200, 100);
        Excel.Chart chartPage = myChart.Chart;

        Excel.SeriesCollection seriesCollection = chartPage.SeriesCollection();
        Excel.Series series1 = seriesCollection.NewSeries();
        series1.XValues = activeSheet.Range["E1","E3"];
        series1.Values = activeSheet.Range["F1","F3"];

        chartPage.ApplyDataLabels(Excel.XlDataLabelsType.xlDataLabelsShowPercent, true,true,false,true,true,true,true);
        chartPage.ChartType = Excel.XlChartType.xlDoughnut;

        Excel.Axis axis = chartPage.Axes(Excel.XlAxisType.xlValue, Microsoft.Office.Interop.Excel.XlAxisGroup.xlPrimary) as Excel.Axis;
}

I just can't figure out how to turn on data labels. I googled everywhere for it but nothing's been helpful so far sadly.

解决方案

Try this (TRIED AND TESTED)

    private void DrawFractionChart(Excel.Worksheet activeSheet, Excel.ChartObjects xlCharts, Excel.Range xRange, Excel.Range yRange)
    {
        Excel.ChartObject myChart = (Excel.ChartObject)xlCharts.Add(200, 500, 200, 100);
        Excel.Chart chartPage = myChart.Chart;

        Excel.SeriesCollection seriesCollection = chartPage.SeriesCollection();
        Excel.Series series1 = seriesCollection.NewSeries();
        series1.XValues = activeSheet.Range["E1", "E3"];
        series1.Values = activeSheet.Range["F1", "F3"];

        chartPage.ChartType = Excel.XlChartType.xlDoughnut;

        Excel.Axis axis = chartPage.Axes(Excel.XlAxisType.xlValue, Microsoft.Office.Interop.Excel.XlAxisGroup.xlPrimary) as Excel.Axis;

        series1.ApplyDataLabels(Excel.XlDataLabelsType.xlDataLabelsShowPercent, true, true, false, true, true, true, true);
    }

One quick question though. If you are not using xRange and yRange then why declare it?

This is the completed code that is tried and tested.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Excel = Microsoft.Office.Interop.Excel;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Microsoft.Office.Interop.Excel.Application xlexcel;
            Microsoft.Office.Interop.Excel.Workbook xlWorkBook;
            Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet;

            object misValue = System.Reflection.Missing.Value;
            xlexcel = new Excel.Application();

            xlexcel.Visible = true;
            // Add a Workbook
            xlWorkBook = xlexcel.Workbooks.Add();

            // Set Sheet 1 as the sheet you want to work with
            xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

            xlWorkSheet.Cells[1, 5] = "Apples";
            xlWorkSheet.Cells[2, 5] = "Oranges";
            xlWorkSheet.Cells[3, 5] = "Pears";

            xlWorkSheet.Cells[1, 6] = "80";
            xlWorkSheet.Cells[2, 6] = "65";
            xlWorkSheet.Cells[3, 6] = "45";

            Excel.ChartObjects myCharts = (Excel.ChartObjects)xlWorkSheet.ChartObjects(Type.Missing);

            // Specified xlWorkSheet.Cells[3, 6], xlWorkSheet.Cells[3, 6] just for the heck of it.
            DrawFractionChart(xlWorkSheet, myCharts, xlWorkSheet.Cells[3, 6], xlWorkSheet.Cells[3, 6]);

            //Once done close and quit Excel
            //xlWorkBook.Close(true, misValue, misValue);
            //xlexcel.Quit();

            //releaseObject(xlWorkSheet);
            //releaseObject(xlWorkBook);
            //releaseObject(xlexcel);
        }

        private void DrawFractionChart(Excel.Worksheet activeSheet, Excel.ChartObjects xlCharts, Excel.Range xRange, Excel.Range yRange)
        {
            Excel.ChartObject myChart = (Excel.ChartObject)xlCharts.Add(200, 500, 200, 100);
            Excel.Chart chartPage = myChart.Chart;

            Excel.SeriesCollection seriesCollection = chartPage.SeriesCollection();
            Excel.Series series1 = seriesCollection.NewSeries();
            series1.XValues = activeSheet.Range["E1", "E3"];
            series1.Values = activeSheet.Range["F1", "F3"];

            chartPage.ChartType = Excel.XlChartType.xlDoughnut;

            Excel.Axis axis = chartPage.Axes(Excel.XlAxisType.xlValue, Microsoft.Office.Interop.Excel.XlAxisGroup.xlPrimary) as Excel.Axis;

            series1.ApplyDataLabels(Excel.XlDataLabelsType.xlDataLabelsShowPercent, true, true, false, true, true, true, true);
        }

        //private void releaseObject(object obj)
        //{
        //    try
        //    {
        //        System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);
        //        obj = null;
        //    }
        //    catch (Exception ex)
        //    {
        //        obj = null;
        //        MessageBox.Show("Unable to release the Object " + ex.ToString());
