+=head1 NAME
+
+tsplotv - plot time series given in vertical format
+
+=head1 SYNOPSIS
+
+tsplotv
+[--finalresolution dpi]
+[--legend-position pos]
+[--log-y]
+[--output-format format ]
+[--stacked]
+[--style style]
+[file ...]
+
+=head1 DESCRIPTION
+
+This program expects time series data in vertical format, I.e.,
+each line contains a tab-separated tripel <time, series, value>. 
+
+The default legend position is "top right", same as with gnuplot.
+Another frequently useful position (especially if you have lots of series)
+is "below". Note that positions which consist of several words (such as
+"top right" need to be passed to tsplotv as a single argument, so the 
+space needs to be hidden from the shell by use of quotes or a backslash.
+
+The default output format is "png", the default style is "lines".
+
+See L<TimeSeries> for a description of possible legend positions,
+output formats, and styles.
+
+The --stacked option causes the time series to be stacked on top of each
+other.
