一列中有多个图表区域 [英] Multiple chart areas in one column

问题描述

我有一个包含多个图表区域的图表.当我按下按钮时，正在创建一个新的图表区域等.我的问题是，在添加一些图表区域后，我得到以下结果:我希望每个图表区域只在一列中，像这样一个接一个:

I have a chart with multiple chart areas. When I press a button a new chart area is being created etc. My problem is that after adding some chart areas I get the following result : I want to have each chart area in only one column, one after the other like this :

这可能吗?

动态添加图表区域

左侧是添加了 3 个图表区域的图表，右侧是具有 4 个区域的图表.

on the left it is the chart with 3 chart areas added and the right is the chart with 4 areas.

使用 Position 属性，请阅读代码中的注释:

Use the Position property and please read comments inside the code:

private void button1_Click(object sender, EventArgs e)
{
    List<ChartArea> Areas = new List<ChartArea>();
    int numberOfAreas = 5;
    chart1.Legends[0].Enabled = false;

    for (int k = 1; k <= numberOfAreas; k++) // YOU WANT 5 and not 4 AREAS - changed k< to k<=
    {
        var S1 = new Series();
        chart1.Series.Add(S1);
        S1.Name = k.ToString();
        for (int j = 0; j < 100; j += 10) S1.Points.AddXY(j, j / 10);
        S1.Color = Color.Transparent;

        Areas.Add(new ChartArea(k.ToString()));
        chart1.ChartAreas.Add(Areas[k - 1]); // IT IS k-1 and not k - we start counting from 0                 
        S1.ChartArea = k.ToString();
        chart1.ChartAreas[k - 1].AlignWithChartArea = chart1.ChartAreas[k - 1].Name;
        chart1.ChartAreas[k - 1].AlignmentStyle = AreaAlignmentStyles.Position;
        chart1.ChartAreas[k - 1].AlignmentOrientation = AreaAlignmentOrientations.Vertical;
    }

    // NOW THE IMPORTANT PART
    float currentHeight = 0;
    foreach (var itm in Areas)
    {
        itm.Position.Height = 100 / numberOfAreas; // Note: the valus are in percenteges and not absolute pixels
        itm.Position.Y = currentHeight;
        itm.Position.X = 5;
        itm.Position.Width = 95;
        currentHeight += 100 / numberOfAreas;
    }

}
