我是否有必要对最佳利用信道表示担忧?
原标题:Do I need to worry about optimal drawing on canvas?

I ve to draw a graph on a canvas (bound by a scrollviewer). And there are about 200 or so nodes in memory.

为使事情简单,我从能够自食其力的用户控制中得出了节点。

但我没有在两点之间打下界线。 我从MSDN知道,

在表面上,地表层和沙皮类相当相似。 两者都用于提供2D图像,而且两者都有类似的具体课程,例如EllipseGeometry和Ellipse。 然而,这两组课程之间有很大差异。 一种情况是,Geometry类缺乏Shape类的某些功能,如能够自我利用。

Because there can be lot many more nodes, the system may render things slowly. Hence, to increase performance, I feel the best choice would be Geometry (custom rendering).

我的问题:

  1. www.un.org/Depts/DGACM/index_spanish.htm 我是否应该与沙皮或地貌相提一下?

  2. www.un.org/Depts/DGACM/index_spanish.htm 我是否应当只给电梯目前的观察区以加快显示速度(在这种情况下,我不得不将电灯从控制变成地貌物体),或者我是否应当只将电灯压在电线上,并在两者之间划线。

  3. www.un.org/Depts/DGACM/index_spanish.htm 我是否应该把图表放在一个轨道地图上,然后把它lip倒? 它更像游戏方案,一般应用方案!

  4. www.un.org/Depts/DGACM/index_spanish.htm 女性生殖器残割是否自动照顾到哪些因素,哪些因素不利于改善业绩?

最佳回答

几个要点是:

议题 我发现,你想要让节们重新思考,因为这样做可能会降低他们的能力。 相反,你要决定什么时候和什么时候? 我是否正确?

然而,从来都不是虚拟的。 我建议通过密码网站下载<代码>WPFToolkit源代码。 在<代码>DataVisualization下,你有几张图表控制的空间(7个ScatterredChart,与你在节点之间没有划定界限的地方类似)及其源代码。 观察他们所做的工作。 他们如何提高其图表工具的业绩。

我也谈到如何执行。 或许可以帮助你迅速使节点变成 can。

1) 地表是轻度,我喜欢。

3] I remember my colleague using even the virtualizing stackpanel with horizontal orientation so that it renders nodes and the unit view i.e. the region specific to one point on X axis so that such repeating regions would automatially fit together to produce a monolithic graph.

Wonder笑!

一切最好,并使我们了解你在这方面取得的进展。
