直接从 csv 绘制带标题的矩阵

Question

我想直接从 csv 绘制一个巨大的矩阵。我在帖子中看到了例子在 TikZ 中将大型二进制矩阵绘制为彩色网格。然而，他们正在导入没有标题的矩阵。

time,input,output,neuron1,neuron2,neuron3
1,0,1,0,0,0
2,0,1,0,0,0
3,0,1,1,1,0
4,0,1,0,0,0
5,1,0,1,0,0
6,1,0,1,0,0
7,1,0,1,1,1
8,1,0,0,0,1
9,1,0,0,1,1
10,1,0,0,1,1
11,1,0,1,1,1
12,1,0,0,1,1
13,1,0,1,0,0
14,1,0,0,1,0
15,1,0,0,0,1
16,1,0,0,0,1
17,1,0,0,0,0
18,1,0,1,0,1
19,1,0,1,1,0
20,0,1,0,1,0
21,0,1,1,1,0
22,0,1,0,0,0
23,0,1,0,0,0

它应该类似于这个：

但是 y 轴显示的是标题。在所提出的文件的情况下，第一个图的 y 轴上应该有输入。第二个图的 y 轴上应该有神经元 1、神经元 2 和神经元 3，依此类推...

我希望您说得够清楚。否则请随时联系我。

我不明白是什么决定了图形的形状。但矩阵图可以非常类似地完成我之前的回答。如果你告诉我是什么决定了情节，我会很乐意尝试一下。
