How to put User-Defined Image into the scatter diagram

iiiJenny commented 5 years ago

Describe your question

在画散点图时，无法将点的形状设置为自定义图片（并设置图片的像素大小）

目前画的图如下：

希望将下图“全部完成”替换“绿色的9个不同位置的点”，像素设置为532 × 140，并覆盖在其他蓝色点上（可以覆盖一部分）长条按钮480

code

（以下代码只给出了绿色点）

import matplotlib.pyplot as plt

xpos = [-300, -300, -300, 0, 0, 0, 300, 300, 300]
ypos = [-533, 0, 533, -533, 0, 533, -533, 0, 533]

fig,ax = plt.subplots(figsize=(6,8))# 设置图大小
ax.set_ylim(800,-800) # 设置坐标轴
ax.set_xlim(-600,600)

# ax.scatter(x, y, marker='o', color='blue', alpha=0.3, edgecolor='black') 蓝色点就先不传数据啦
ax.scatter(xpos, ypos, marker='o', color='green')
plt.title('hotzone scatter plot ')

长条按钮480

from PIL import Image
im_path = '长条按钮480.png'
target = Image.open(im_path)
target

@hupili Could you please help me？

最后希望呈现的效果大致是这样～（图片像素大小为：532 × 140）

ax.scatter(x, y, marker='o', color='blue', alpha=0.3, edgecolor='black') 蓝色点就先不传数据啦

It is good to have some sample data -- you can generate some random ones if the data is commercial secret.

import csv
import pandas as pd

df = pd.read_csv('cleaning_10.csv')

x = df['cursor_x']
y = df['cursor_y']

数据： cleaning_10.csv
