在图表上绘制线（y = 2x + 7） [英] Plot a line (y = 2x + 7) on a graph

问题描述

我正在使用C＃中的一个科学计算器。我有解析引擎等，现在我想添加一个图，所以用户可以绘制一条线。有没有任何种类的控制，让我输入一个函数，它会在图表中绘制一条线？

取斜率截距形式的线性方程，例如：

  f（x）= 2x + 7 
  

主要目的是允许用户在文本框中写入 2x + 7 ，然后它将绘制线条。最好是使用自定义函数而不仅仅是线性函数，例如：

 （（x  -  8）* 4 ^ 2）/（7.136 + x）
  

但不是必须的。这是否有第三方控制？

我已经下载了一个程序，用来绘制如下的函数：

解决方案

我搜索了

我在Visual C＃2010 WinForms应用程序中如何实现这个功能？ code> windows 的数学函数图库并找到：

• FPlot a用于绘制函数的.NET库和测量数据（CodeProject上的项目）

，您可以尝试使用以下源代码：

• MathGV


• 图

我没有尝试任何这些，顺便。




I am working on a scientific calculator in C#. I have the parsing engine and such, now I would like to add a graph so the user can plot a line. Is there any kind of control that will let me input a function and it will graph a line in the chart? I'm not talking about plotting individual points by the way.

Take this linear equation in slope-intercept form for instance:

f(x) = 2x + 7

The main goal is to allow the user to write 2x + 7 in a textbox, and then it will graph the line. It would be preferable if custom functions could be used other than just linear functions, such as:

((x - 8) * 4^2)/(7.136 + x)

But it's not a requirement. Is there a third-party control for this? If not could someone give me general help on how I would create such a control?

I have downloaded a program that graphs functions like this:

Can anyone help me on how I can achieve this functionality in my Visual C# 2010 WinForms application?

解决方案

I searched for mathematical function plot library for windows and found this:

• FPlot a ".NET library for plotting functions and measurement data" (a project on CodeProject)

and you can try to use the source code of:

• MathGV
• Graph

You'll have to check the licenses. I didn't try any of these, by the way.
