使用 C 编程实时绘制图形
大家好，有没有一种方法可以使用 C 编程绘制实时图形。就像我在 csv 文件中存储了一些值一样，我将添加列的值并将它们绘制在图表中。实时绘图仪可以在我的应用程序仍在计算数据时自动更新数据图表。以及如何我将图形附加到 GUI 中，并在我的 C 程序中使用该图形绘图仪。
谢谢任何帮助，我们将不胜感激。
hi every one is there a way by which i can draw live graph using c programming. like i have some values stored in a csv file i will add values of the column and plot them in a graph.a real-time plotter that can automatically update graphs of my data while it is still being computed by my application.and how can i append the graph in a gui.and use that graph plotter in my c program.
thanks any help will be appreciated.

gnuplot 可以从管道读取数据，这样您就可以从代码中更新绘图 - 而且您不必这样做自己处理任何 GUI 或窗口代码
gnuplot can read data from a pipe so you can update the plot from your code - and you don'y have to handle any gui or windowing code yourself
我建议您从一些 GTK 编程教程开始。
这是一个简单的线条画教程/示例，可以帮助您入门。

还有一些你认为它应该是什么样子的草图（用笔在纸上）。
既然您说您对此作为编程练习感兴趣，那么我还提供以下提示：
您将需要找出以下问题的答案：
祝您好运，当您遇到困难时返回 stackoverflow
I suggest you start by doing some GTK programming tutorials.
Here's a simple tutorial/example of line drawing to get you started.

Also so some sketches (with a pen, on paper) of what you think it should look like.
Since you said you are interested in this as a programming exercise, I also offer the following hints:
You will need to work out answers to the following questions:
Good luck, and come back to stackoverflow when you get stuck
