WPF中的图表缩放 [英] Chart scaling in WPF

问题描述

大家好，

我有一个图表线(例如，窦)作为WPF折线对象呈现.现在，我有一个画布对象要在其上放置该行.

canvas1.Children.Add(myPolyline);

现在在画布上显示了窦，但是只有一个小(小)曲线在画布上.有没有办法缩放折线，使其适合整个画布?我必须自己计算该转换，还是WPF中有任何支持.

任何帮助都将非常有用.

干杯，
Franz

Hi together,

I have got a chart line (e.g. a sinus) which is presented as a WPF polyline object. Now I have a canvas object where I want to put that line on.

canvas1.Children.Add(myPolyline);

Now the sinus is shown on the canvas, but only a small (little) curve on the canvas. Is there a way to scale that polyline so that it fits on the whole canvas? Do I have to calculate that transformation by myself or is there any support in the WPF.

Any help would be great.

Cheers,
Franz

推荐答案

画布支持显式布局(您必须显式指定x和y坐标).这几乎意味着，您需要检测画布大小何时更改，并适当地缩放线条.

Canvas supports explicit layout (you have to specify the x and y coordinates explicitly). This pretty much means, you need to detect when the canvas size changes and scale your line appropriately.

为什么不将行添加到隐式提供布局支持的面板类型中(例如DockPanel，GridPanel等)?

Why don't you add the line into a panel type that provides layout support implicitly (e.g. DockPanel, GridPanel, etc)?
