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.LogFolderlogqbit.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 PySide6pyqtgraph 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。
