plot_datafile_columns.py

"""
Imports a text-based data file and plots multiple specified columns
into a single scatter graph in OriginPro.

This script performs the following steps:
1.  Reads a tab-delimited text file into a pandas DataFrame.
2.  Imports the DataFrame into a new worksheet in the current Origin project.
3.  Creates a new graph using a 'scatter' template.
4.  Iterates through a specified range of column indices, plotting each one
    as a separate data series against the first column (index 0) on the X-axis.
5.  Groups all the plots on the graph layer to apply uniform styling.
6.  Customizes the grouped plots with a 'Candy' colormap, varied symbol
    shapes, and a larger symbol size.
7.  Adjusts the legend's font size, position, and removes its frame.
8.  Finally, rescales the axes to fit all plotted data.
