我使用 Python 制作了下面显示的图（保存为 png）。
它应该有一个通用的颜色条，并且所有数据都是从h5文件中读取的，但我认为将它保存到 txt 文件或使用 Python 脚本读取 TikZ 图形。
共有 5 个图和 1 个色条：
第一个图只有一个变量（值为 0、25、33、50、66、75%），每个彩色方块代表相应的输出，可以用长度为 6 的数组表示。
另外四个图有两个变量（值为 [0,25,33,50,66,75 %] 和 [0,1,2,3,4,5,6,7,8]），因此可以用 6x9 矩阵表示。
我想制作一个像 PNG 一样的 TikZ 图形，但当然带有不重叠的文本，也许每个子图都有一个标题以及更好的颜色条轮廓（png 很快且很脏，能够快速查看输出）。
有人可以帮我从这里出去吗？
（如果这些值有用，请告诉我最简单的格式，我会txt尽快上传文件。）
编辑：添加数据data.txt
编辑2：我忘了说我希望能够使用文件中定义的 \figureheight 和 \figurewidthtex来调整尺寸（就像我在图中所做的那样）另一个问题）。
答案1
因为我对自己能取得的成绩不满意pgf图，我尝试自己写一些东西。基本上它是一个 foreach 循环，它计算特定值的颜色，然后绘制一个正方形。有一些障碍，因为我了解到你需要\xglobal将颜色定义全局化。结果仍然远非自动化，但我正在考虑通过添加一个键值接口鍵盤。无论如何，以下是我目前所拥有的：
