This plugin is open source. You can edit and distribute it freely but cite this plugin and Mapcurve (Hargrove et al. 2006) if you are using it to develop another plugin. PyQGIS and OSGeoW environment must be integrated to your IDE if you want use or develop or build from source. Here some command to integrate that from Command Prompt in Windows.

    @echo off
    path %PATH%;%QGIS_PATH%\bin
    path %PATH%;%QGIS_PATH%\apps\grass\grass-78\lib
    path %PATH%;%QGIS_PATH%\apps\Qt5\bin
    path %PATH%;%QGIS_PATH%\apps\Python36\Scripts

    set PYTHONPATH=%PYTHONPATH%;%QGIS_PATH%\apps\qgis\python
    set PYTHONHOME=%QGIS_PATH%\apps\Python37  

    start "VisualStudioCode for QGIS" /B  "%VISUAL_STUDIO_CODE_PATH%\code.exe" %YOUR_PLUGIN_REPOSITORY% %*

or you can configure with Anaconda. (Install QGIS in Anaconda first)

Here some command for integrating terminal with PyQGIS and OSGeoW in Visual Studio Code.

    @echo off
    call "%QGIS_PATH%\bin\o4w_env.bat"
    call "%QGIS_PATH%\qt5_env.bat"
    call "%QGIS_PATH%\py3_env.bat"
    call "%OSGeo4W64_PATH%\bin\o4w_env.bat"
    call "%OSGeo4W64_PATH%\bin\qt5_env.bat"
    call "%OSGeo4W64_PATH%\bin\py3_env.bat"
    call "%OSGeo4W64_PATH%\bin\gdal-dev-env.bat"
    call "%OSGeo4W64_PATH%\bin\gdal-dev-py3-env.bat"
    call "%OSGeo4W64_PATH%\bin\proj-dev-env.bat"

    @echo on
    pyrcc5 -o resources.py resources.qrc

You can deploy the plugin by copying the repository to plugins QGIS folder or you can deploy it with pb_tool with command pb_tool zip. The new plugin can be operated by restarting the QGIS first or using extension called Plugin Reloader. Plugin Reloader available in QGIS Plugin Repository (see https://plugins.qgis.org/plugins/plugin_reloader/).
