+**Syntax**
+
+This tool creates a simple scatter plot between two variables containing numeric values of a selected dataset. 
+
+- All invalid, blank and comment lines in the dataset are skipped.  The number of skipped lines is displayed in the resulting history item.
+
+- **Plot title** The scatterplot title
+- **Label for x axis** and **Label for y axis** The labels for x and y axis of the scatterplot.
+
+-----
+
+**Example**
+
+- Input file::
+
+    1   68  4.1
+    2   71  4.6
