pyqt5使用pyqtgraph實(shí)現(xiàn)動(dòng)態(tài)熱力圖

一、效果圖

二、流程

1、打開Designer創(chuàng)建一個(gè)UI界面
2、把UI轉(zhuǎn)成py
3、創(chuàng)建一個(gè)main.py文件
4、在main文件中渲染畫布、創(chuàng)建初始數(shù)據(jù)、畫熱力圖、創(chuàng)建更新數(shù)據(jù)線程、綁定按鈕觸發(fā)事件

三、UI界面

其中h_map.py代碼如下:

# -*- coding: utf-8 -*-# Form implementation generated from reading ui file 'h_map.ui'
