iphone - Creating a spectrogram in iphone for a fixed length of data samples

Question

I am pretty new to iOS programming and i need to create and display a spectrogram given a fixed length array of samples. Is it possible to display it using core plot? If so, how? I would really love to have some help on this.

Answer 1

尝试创建一个 2D 彩色位图并使用核心图形而不是使用核心绘图来显示该位图。
