Question

我的Windows窗体应用程序项目中存在图表绘制问题。

我想画一个这样的图表： http://upload7.ir/imgs/2014-12/84930837744513480976.jpg

X轴和Y轴上的单词是相关的，彩色矩形中的字母是每个关系的值。我想要一张这样的图表。谁能帮我画那样的东西？我要感恩。

问候。

Answer 1

你的问题很模糊，但如果你想要那个图表，这是否意味着你不需要这些值是动态的？如果是这样，最简单的解决方案是将其保存为图像并在您需要的应用程序中显示图像。显然，如果您需要动态的值或颜色，这将无法工作。

Answer 2

这是一个类AreaChart，它绘制的图表就像你展示的那样。

这是它的外观，内置值：

AreaChart

将类添加到项目中并进行编译。它将显示在工具箱中，您可以将其放在表单上。（在你这样做之前备份你的项目！）

您可以在设计器或代码中设置多个值，包括尺寸BackColor, Font, and Labels ..使用提供的方法在代码中设置颜色和文本！

using System.Windows.Forms;
using System.Drawing;
using System.ComponentModel;

class AreaChart : Panel
{
     [Category("Appearance"), Description("Padding around the ChartArea")]
    public Padding ChartPadding { get; set; }
     [Category("Appearance"), 
              Description("Axixs Origin offsets from Bottom Left of the Chart")]
    public Point AxisOriginOffset { get; set; }
     [Category("Appearance"),Description("Number of Rows")]
    public int RowNum { get; set; }
     [Category("Appearance"), Description("Number of Columns")]
    public int ColNum { get; set; }

     [Category("Appearance"), Description("Labeltexts for Y-Axis")]
    public string[] labelsY { get; set; }
     [Category("Appearance"), Description("Labeltexts for X-Axis")]
    public string[] labelsX { get; set; }

    Color[][] colors { get; set; }
    string[][] texts { get; set; }

    Rectangle chartArea = Rectangle.Empty;
    Point axisOrigin = Point.Empty


    public void Init()
    {
        chartArea = new Rectangle(ChartPadding.Left, ChartPadding.Top,
                    this.Width - ChartPadding.Left - ChartPadding.Right, 
                    this.Height - ChartPadding.Top - ChartPadding.Bottom);

        axisOrigin = new Point(AxisOriginOffset.X, this.Height - AxisOriginOffset.Y);

        colors = new Color[RowNum][];
        for (int r = 0; r < RowNum; r++) colors[r] = new Color[ColNum];
        texts = new string[RowNum][];

    }


    public AreaChart()
    {
        ChartPadding = new Padding(80, 40, 40, 40);
        AxisOriginOffset = new Point(60, 20);
        RowNum = 3;
        ColNum = 2;
        BackColor = Color.AntiqueWhite;

        Init();
    }

    protected override void OnPaint(PaintEventArgs e)
    {
        if (this.DesignMode) Init();      // make the designer show the current
        if (this.DesignMode) InitDemo();  // ...sizes, colors and texts

        int x = chartArea.X;
        int y = chartArea.Y;
        SizeF tSize = e.Graphics.MeasureString("XX", this.Font, 9999);
        int th = (int)tSize.Height / 2;
        int tw = (int)tSize.Width / 2;
        int h = chartArea.Height / RowNum;
        int w = chartArea.Width / ColNum; e.Graphics.Clear(BackColor);

        e.Graphics.DrawLine(Pens.Black, axisOrigin, 
                            new Point(axisOrigin.X, chartArea.Top));
        e.Graphics.DrawLine(Pens.Black, axisOrigin, 
                            new Point( chartArea.Right, axisOrigin.Y));

        for (int r = 0; r < RowNum; r++)
            for (int c = 0; c < ColNum; c++)
            {
                e.Graphics.FillRectangle(new SolidBrush(colors[r][c]), 
                  x + c * w, y + r * h, w, h);
                e.Graphics.DrawRectangle(Pens.Black, x + c * w, y + r * h, w, h);
                e.Graphics.DrawString(texts[r][c], this.Font, Brushes.Black, 
                  x + c * w  + w / 2 - tw, y + r * h + h / 2 - th);

            }
        for (int r = 0; r < RowNum; r++)
            e.Graphics.DrawString(labelsY[r], this.Font, Brushes.Black, 
              AxisOriginOffset.X - tw * 2, y + r * h + h / 2 - th);  //*

        for (int c = 0; c < ColNum; c++)
            e.Graphics.DrawString(labelsX[c], this.Font, Brushes.Black,
                x + c * w + w / 2 - tw, axisOrigin.Y );             //*

        base.OnPaint(e);;
    }

    public void setColor (int row, int col, Color color)
    {
        try
        {
            colors[row][col] = color;
        } catch { throw new Exception("setColor : array index out of bounds!"); }
    }

    public void setText(int row, int col, string text)
    {
        try
        {
            texts[row][col] = text;
        } catch { throw new Exception("setText: array index out of bounds!"); }
    }

    public void setLabelX(int col, string text)      //*
    {
        try
        {
            labelsX[col] = text;
        } catch { throw new Exception("array index out of bounds!"); }
    }

    public void setLabelY(int row, string text)      //*
    {
        try
        {
            labelsY[row] = text;
        } catch { throw new Exception("array index out of bounds!"); }
    }

    public void InitDemo()
    {
        setColor(0, 0, Color.Plum);
        setColor(1, 0, Color.GreenYellow);
        setColor(2, 0, Color.Gold);
        setColor(0, 1, Color.LightSkyBlue);
        setColor(1, 1, Color.NavajoWhite);
        setColor(2, 1, Color.Pink);

        setText(0, 0, "AA");
        setText(1, 0, "BA");
        setText(2, 0, "CA");
        setText(0, 1, "AB");
        setText(1, 1, "BB");
        setText(2, 1, "BC");

        setLabelY(0, "A");     //*
        setLabelY(1, "B");     //*
        setLabelY(2, "C");     //*

        setLabelX(0, "A");     //*
        setLabelX(1, "B");     //*
    }


}

在您的表格Initializecomponent()之后，您应该致电

areaChart1.Init();
areaChart1.InitDemo();

显示我显示的演示图表。要更改它，请使用以下调用：

areaChart1.ColNum = 3;
areaChart1.Init();
areaChart1.InitDemo();
areaChart1.setColor(0, 2, Color.Yellow);
areaChart1.setLabelY(2, "ZZ");
//..
