gnuplot statistics with time data (converted from string as float) fails as single argument
<p>I have a data file with time data as one column. Since the <code>stats</code> command is not compatible with time data(<code>Stats command not available in timedata mode</code>), we have to do some conversion first:</p>

<pre><code>set xdata
stats 'data' u (strptime(fmt,strcol(1)))
</code></pre>

<p>this does not work however. gnuplot prints the following error: <code>All points out of range</code></p>

<p>I don't know why, but I had the idea to use a second artificial column:</p>

<pre><code>stats 'data' u (strptime(fmt,strcol(1))):(1.0)
</code></pre>

<p>This works as intended (<strong>why?</strong>), but with an unnecessary second column. For me, this "workaround" is ok, because I don't have big data files to plot, but if people had... This could be quite annoying.</p>

<p>Did I miss something?<br>
Why does gnuplot stats behaves this way?<br>
Is this a bug, worth reporting?</p>
