+.. 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
