如何绘制四个（或更多）水平workareas？ [英] how to draw four (or more) workareas horizontally?

问题描述

下面是其中提请1/2/3/4码和平（取决于备注）图表：

Here is a peace of code which draws 1/2/3/4 (depends on remarks) charts:

private void button1_Click(object sender, EventArgs e)
    {
        List<int> queue = new List<int>();
        queue.Add(1); queue.Add(2); queue.Add(3); queue.Add(4);
        chart1.ChartAreas.Add(queue[0].ToString());
        chart1.ChartAreas.Add(queue[1].ToString());
        chart1.ChartAreas.Add(queue[2].ToString());
        chart1.ChartAreas.Add(queue[3].ToString());
        chart1.Series.Add("test1");
        chart1.Series.Add("test2");
        chart1.Series.Add("test3");
        chart1.Series.Add("test4");
        chart1.Series["test1"].ChartArea = "1";
        chart1.Series["test2"].ChartArea = "2";
        chart1.Series["test3"].ChartArea = "3";
        chart1.Series["test4"].ChartArea = "4";
        Random rdn = new Random();
        for (int i = 0; i < 50; i++)
        {
            chart1.Series["test1"].Points.AddXY(rdn.Next(0, 10), rdn.Next(0, 10));
            chart1.Series["test2"].Points.AddXY(rdn.Next(0, 10), rdn.Next(0, 10));
            chart1.Series["test3"].Points.AddXY(rdn.Next(0, 10), rdn.Next(0, 10));
            chart1.Series["test4"].Points.AddXY(rdn.Next(0, 10), rdn.Next(0, 10));
        }
        chart1.Series["test1"].ChartType = SeriesChartType.FastLine;
        chart1.Series["test2"].ChartType = SeriesChartType.FastLine;
        chart1.Series["test3"].ChartType = SeriesChartType.FastLine;
        chart1.Series["test4"].ChartType = SeriesChartType.FastLine;
    }

如果我画两个或三个图表其水平似乎是这样的：

If I draw two or three charts it appears horizontally something like:

............

............

...........

............

或

............

............

............

............

............

............

当我加入第四chartarea它开始打造第二个列

When I add fourth chartarea it starts create second "column"

.......... .. ............

............ ............

............ ......... ...

............ ............

怎样做才能迫使布局有一列？我已经找到位置属性，但无法找到如何正确地使用它的方式：（

What to do to force layout with one column ? I have found "Position" property but couldn't find the way how to use it correctly :(

推荐答案

我认为所有的对齐属性居然比对区本身..

I think all the alignment properties actually are more about data aligning than about the areas themselves..

貌似默认的了解数据对齐位置=自动将与有关如何最好地利用空间，直到你关掉自己的想法赢，所以我相信，你必须设置位置 > ChartAreas 中的代码下面是玩一个例子：

Looks like the default Position = Auto will win with its own ideas about how to use the space best, until you switch it off; so I believe that you have to set the Positions of the ChartAreas in code. Here is an example to play with:

float dist = 1f;
float h = 23f;
float w = 80f;

CA1.Position = new ElementPosition(dist, dist * 2 + h * 0, w, h);
CA2.Position = new ElementPosition(dist, dist * 3 + h * 1, w, h);
CA3.Position = new ElementPosition(dist, dist * 4 + h * 2, w, h);
CA4.Position = new ElementPosition(dist, dist * 5 + h * 3, w, h);

这四个数字的的 ElementPosition 是持有总图表区的百分比（！）浮动。我已经允许了一点距离，并设置ChartAreas至23％的高度和80％的宽度。

The four numbers of an ElementPosition are floats that hold percentages (!) of the total chart area. I have allowed a little distance and set the ChartAreas to 23% height and 80% width.

好消息是，这些数字将调整期间举行..

The good news is that these numbers will hold during resize..

这不是奇怪的是，这些东西所以非常难找了呢？ （这是我第3次尝试吧..）

Isn't is strange that these things are so very hard to find out? (This is my 3rd try at it..)
