    Since StripTool defines the same line width for all curves while TimeChart lets each curve have its own line width,
    here we must import the global StripTool line width, save it to a global variable, and then, whenever it's time
    to provide the line width for a curve, retrieve the global line width variable to assign to that curve.

    line_width_value : str
        The line width as set by the StripTool config file.
