参数大小不成比例的气泡图 [英] Unproportional Bubble Chart with the size paramater

问题描述

我创建了一个气泡图，并输入了一些测试值，如下所示:

I´ve created a bubble chart and I put in some testing values as follow:

    this.chart1.Series["blueBubble"].Points.AddXY(2, 3, 6);
    this.chart1.Series["redBubble"].Points.AddXY(1, 0, 7);
    this.chart1.Series["yellowBubble"].Points.AddXY(1, 3, 8);

当我将特定气泡的大小放入AddXY函数的第三个参数时，按完全错误的比例表示法进行大小调整.见图片:

As I put in the size of the particular bubble to the third parameter of AddXY function, the sizing is done in a completely wrong proportional representation. See picture:

如何将气泡大小更改为正确的命题表示形式?

How can I change the bubble sizes to the right proposition representation?

推荐答案

这看起来很奇怪.

我最好的解释是，大小总是从最小的一组开始，然后按比例将其从1缩放到最大的一组.

The best explanation I have is that the sizes always start with the smallest one set and scale them going from 1 to the largest one set in proprtional steps.

听起来很奇怪?是的.

以下是 BubbleScaleMax 和 BubbleScaleMin

如果设置为自动"，则使用 最小尺寸.

If set to Auto, the smallest plotted bubble is displayed using the minimum size.

如果设置为自动"，将使用 最大尺寸.

If set to Auto, the largest plotted bubble will be displayed using the maximum size.

将这些属性设置为除Auto以外的其他任何选项都非常棘手；您可以使用此:

Setting these properties to anything else but Auto is tricky; you could use this:

 chart1.Series[0]["BubbleScaleMin"] = "0";

或者小于您的最小尺寸的任何数字小.

Or any number smaller than your smallest size.

或者，如果您愿意，这是一种解决方法:添加一个透明的虚拟点，其大小= 0并具有合适的x和y值:

Or, if you prefer, here is a workaround: Add a transparent dummy point with size = 0 and suitable x- and y-values:

int i = this.chart1.Series[0].Points.AddXY(1, 1, 0);
this.chart1.Series[0].Points[i].Color = Color.Transparent;
