.. class:: infomark

This tool allows you to plot values contained in columns of a dataset against each other and also allows you to have different series corresponding to the same or different datasets in one plot.

-----

.. class:: warningmark

This tool throws an error if the columns selected for plotting are absent or are not numeric and also if the lengths of these columns differ.

-----

**Example**

Input file::

    1   68  4.1
    2   71  4.6
    3   62  3.8
    4   75  4.4
    5   58  3.2
    6   60  3.1
    7   67  3.8
    8   68  4.1
    9   71  4.3
    10  69  3.7

Create a two series XY plot on the above data:

- Series 1: Red Dashed-Line plot between columns 1 and 2
- Series 2: Blue Circular-Point plot between columns 3 and 2
