-''Profile plot''
+'''Profile plot''' -  User can choose on which raster to draw the profile and which is the display unit (meter, foot or unknow) of the raster. Note that the display unit has only an effect on the label profile and on raster statistics. It is not an unit converter
 <br />
 The following check boxes allow either to draw a linestring as trace or to use a selected linestring as base trace for the profile, These option will be operative wnhe the dialog is closed using the '''OK''' button
 <br />
-''Options''
+'''Options''' - The Options fileds allow to define the text on both horizontal and vertical axes of the profile
