Plot benchmark's result in Go
问题
假设我已经编写了不同的函数来计算斐波那契数列的第n个数字：
func fiboIterative(n int) {
...
}
func fiboRecursive(n int) {
...
}
我想要获得一个图表，显示每个函数在不同n值下的性能。
到目前为止，我一直在使用内置的testing包进行基准测试，它会将每个操作的时间打印到控制台。是否有一种简单的方法/包可以运行多个n值的基准测试，将结果存储在csv文件或类似的文件中，然后绘制它们的图表？
英文:
Let's say I have written different functions to compute Fibonacci's nth number:
func fiboIterative(n int) {
...
}
func fiboRecursive(n int) {
...
}
And I'd like to get a chart showing the performances of each function depending on the value of n.
So far, I have been benchmarking using the built-in testing package which prints the time per operations to the console. Is there a simple way/package to run the benchmark for multiple values of n, stores the result in a csv or something similar and then plot them?

我本来期望这样的功能会被内置进来...提供一个没有这个功能的基准测试工具确实有些奇怪。
在语言包中包含一个跨平台的绘图库似乎并不明显，这将需要进行维护。
目前，你需要依赖第三方项目来进行基准测试的绘图功能。
例如，项目 aybabtme/benchkit 可以从基准测试生成 svg 绘图。

It doesn't seem obvious to include a cross-platform plot library within the language packages, that will have to be maintained.
As it is now, you need to rely on third-party projects for a plot feature for benchmarks.
For example, the project aybabtme/benchkit generates svg plot pictures from benchmarks.
