Simple data logger and live plotter for lab-scale experiments.
Project description
LogQbit
LogQbit 是一个面向实验室场景的轻量数据记录工具包,适合记录中小规模实验数据。
它的核心设计目标是:
- 用简单的接口和运行逻辑实验数据。
- 基于目录的实验数据组织,用通用可读的格式储存数据。
- 在需要时再启用浏览器和实时绘图等 GUI 能力。
完整文档见:https://qiujv.github.io/logqbit/
安装
常规安装:
pip install logqbit
如果你不想让安装过程修改当前 Python 环境,可以跳过依赖解析:
pip install --no-deps logqbit
通常 logqbit.logfolder.LogFolder、logqbit.registry.Registry 等核心接口仍然可用;
但浏览器、实时绘图和快捷方式等 GUI 功能仍然依赖 PySide6、pyqtgraph 等组件。
更详细的安装说明见:https://qiujv.github.io/logqbit/install/
用例
用例 1:记录一组实验数据
from pathlib import Path
from logqbit.logfolder import LogFolder
lf = LogFolder.new("./demo_data", title="My Experiment")
lf.add_row(x=0.0, y=1.2)
lf.add_row(x=1.0, y=1.8)
lf.flush()
lf.meta.plot_axes = ["x"]
lf.const["temperature"] = "300 K"
print(lf.df)
用例 2:打开数据查看器
logqbit browser
或者也可以通过 logqbit shortcuts 创建桌面快捷方式(仅 Windows 可用)。
用例 3:快速生成示例数据并打开浏览器
logqbit browser-demo
这会在当前目录创建 logqbit_example/,生成多组示例数据,并启动图形化浏览器。
