C#-实时绘制数据 [英] C# - Realtime Plotting of data

问题描述

Hii

我正在一个项目中，我要连续绘制来自串行端口的数据[数据超过4小时].我可以画线图.但是我想通过滚动查看从头到尾的情节.请给我一个解决方案.

Hii

I am working on a project in which i want to plot the data coming from serial port continuously [data more than 4 hrs]. I can draw the line graph. But I want to see the plot from start to end by scrolling. Please give me a solution.

推荐答案

我也有类似的要求，我的解决方案是使用graphicspath ...我将点添加到比例为1:1的图形路径中然后在绘制到屏幕上时，我使用矩阵函数缩放要显示的迹线，并使用裁剪区域仅在屏幕上显示我想要的部分.快速有效.

要使用的对象(假设g是当前图形对象)

设置

g.Clip =在屏幕显示区域上作为剪辑区域:

GraphicsPath gx = new GraphicsPath();

添加线，路径，矩形等...

gx.Transform(缩放和滚动图形)

g.DrawPath(实际上绘制轨迹)

I had a similar requirement, my solution was to use graphicspath ... I add the points to a graphics path scaled 1:1 then when drawing to the screen I use the matrix functions to scale the traces for display and the clip region to only show the part I want on screen. Works a treat and really fast.

Objects to use ( assumes g is the current graphics object)

Set

g.Clip = on screen display area as a clip region:

GraphicsPath gx = new GraphicsPath();

Add line, paths, rectangles etc ......

gx.Transform( to scale and scroll graph)

g.DrawPath( actually draw traces )

我的工作类似，但是数据来自以太网.
