单击按钮增加条形图值

Question

我正在尝试创建一个图表，以显示锻炼的进度。每单击五个按钮，应将一个勾号添加到图形中。这是外观的一个例子。

出于演示目的，我使用按钮点击，在生产中，点击是车轮每旋转20圈。

    private int counter = 0;
    private void button1_Click(object sender, EventArgs e)
    {
        counter++;
        // code will go here
    }

提前致谢

您可以使用 aBitmap Buffer或 apanel进行绘制。这是一个先机：只是一个示例。 参考。

该解决方案基于WinForms& Panel_Paint()。您可以尝试添加垂直进度标签和图表的Y轴值标签。

代码：

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;

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

        private int counter = 0;
        private int px = 10;
        private int py = 180;
        private int total5Clicks = 0;

        private void button1_Click(object sender, EventArgs e)
        {
            counter++;
            label1.Text = "Total Clicks = " + counter.ToString();
            if (Math.Abs(counter % 5) == 0){
                if (Math.Abs(counter / 5) > 0){
                    total5Clicks = total5Clicks + 1;
                    PaintOnChartPanel(total5Clicks);}
             }
         }

      private void panel1_Paint(object sender, PaintEventArgs e){           
      }

      private void PaintOnChartPanel(int total5Times)
      {            
        //Add a new Panel Paint EventHandler
        panel1.Paint += new PaintEventHandler(panel1_Paint);

        using (Graphics g = this.panel1.CreateGraphics())
        {
            Brush brush = new SolidBrush(Color.Green);
            g.FillRectangle(brush, px, py, 20, 20);                           
            Pen pen = new Pen(new SolidBrush(Color.White));
            g.DrawRectangle(pen, px, py, 20, 20);                    

            //add each total5Click into chart block
            g.DrawString((total5Times).ToString(), new Font("Arial", 7), 
            new SolidBrush(Color.AntiqueWhite),
            px + 1, py+8, StringFormat.GenericDefault);
            pen.Dispose();}

            if (py > 20){
                py = py - 20;}
            else{
                MessageBox.Show("Reached Top of the Panel");
                if (px < 200){
                    px = px + 20;
                    py = 180;}
                else{
                    MessageBox.Show("Reached Right of the Panel");
                }
            }
        }
    }
}

输出形式：
