以编程方式设置 Silverlight 图表 ControlTemplate
5.00/5 (2投票s)
演示如何以编程方式编写 Silverlight Chart ControlTemplate 的代码。
引言
我们一直在寻找一种方法，以便以编程方式（代码隐藏）为 Silverlight 中的 Chart 控件创建 ControlTemplate。经过大量搜索，并将来自博客、提示和编码者网站的信息拼凑在一起，我们想出了一种从代码隐藏创建 ControlTemplate 的方法。
这工作起来相当简单。在 XAML 部分放置一个图表控件，给它一个 x:Name，然后从代码隐藏创建图表内部结构。
MainPage.xaml
以下是在主页面上设置的图表 XAML，名称为“cChart”。简单，只是一个图表和一些数据点来显示列。没有设置 ColumnSeries、Axis、Style 或 ControlTemplate。

代码隐藏 - MainPage.xaml.cs
这通过设置一个 ControlTemplate 然后将其放置到 ColumnDataPoint 样式中来添加到 cChart，然后将其添加到 ColumnSeries，最后添加到 cChart。

有关颜色的附加代码
我们真的不喜欢使用像 argb 这样的原始颜色。大多数时候我们都在猜测，并且想出一个令人满意的配色方案的过程从未真正奏效。控件从未好过，所以我们搜索了几种方法，并在 http://en.wikipedia.org/wiki/HSL_and_HSV 上找到了一些关于颜色的好信息。 从那里，我们合并了两种不同的尺度类型，色度和饱和度，以提出一个可移动的尺度来使用。 它可以是所有色度、所有饱和度或介于两者之间。

结果
以下图像来自运行应用程序，其中 Column Series 的数量 ... int a = 3; // Number of Column Series ... 设置为 1、3 和 5。每个系列根据系列的数量使用上述颜色代码更改颜色。 我们有一个实时演示，显示了 10 个 Column Series，请访问 此处。
展开提示
首先，设置样式。 这应该让你对如何处理其他控件的样式编码有一些想法。
其次，创建 controltemplate。 这使得可以将 controltemplate 应用于其他控件。
第三，操作 controltemplate。 这展示了如何插入值，并且可以扩展为包括代码隐藏中 XAML 代码的完整描述（以编程方式）。
第四，添加样式。 样式可以以类似的方式应用于其他控件。
第五，设置图表轴。 我们放置了一个代码隐藏轴，它还可以包括其他属性设置。
第六，颜色控制。 应用 HCBPAtoARGB() 画笔比猜测更好地控制颜色。

嗯，就在这里。
