Matplotlib 绘制盒子

发布于 2024-09-25 06:14:06 字数 408 浏览 3 评论 0原文

我有一组数据，其中每个值都有一个 (x, y) 坐标。不同的值可以具有相同的坐标。我想把它们画在一个矩形的盒子集合中。

例如，如果我有数据：

A -> (0, 0)
B -> (0, 1)
C -> (1, 2)
D -> (0, 1)

我想得到以下绘图：

    0   1   2
  +++++++++++++
0 + A + B +   +
  +   + D +   +
  +++++++++++++
1 +   +   + C +
  +++++++++++++
2 +   +   +   +
  +++++++++++++

如何使用 Matplotlib 在 Python 中完成它？

谢谢！

I have a set of data, where each value has a (x, y) coordinate. Different values can have the same coordinate. And I want to draw them in a rectangular collection of boxes.

For example, if I have the data:

A -> (0, 0)
B -> (0, 1)
C -> (1, 2)
D -> (0, 1)

I want to get the following drawing:

    0   1   2
  +++++++++++++
0 + A + B +   +
  +   + D +   +
  +++++++++++++
1 +   +   + C +
  +++++++++++++
2 +   +   +   +
  +++++++++++++

How can I do it in Python using Matplotlib?

THANKS!

只是想，也许你真正想知道的只是这个：

def drawbox(list,x,y):
  # write some graphics code to draw box index x,y containing items 'list'

[[drawbox(u,x,y) for u in X.keys() if X[u]==(y,x)] for x in range(0,3) for y in range(0,3)]

Just thought, maybe what you actually wanted to know was just this:

def drawbox(list,x,y):
  # write some graphics code to draw box index x,y containing items 'list'

[[drawbox(u,x,y) for u in X.keys() if X[u]==(y,x)] for x in range(0,3) for y in range(0,3)]
