If I use one xml-file in more than one plot the plugin isn't working anymore. It simply doesn't store the values anymore.

I try to generate one plot for <rom> and one for <ram> from this data which is stored in one file:

<rom>
  <Total>343284</Total>
  <Config>102031</Config>
</rom>
<ram>
  <Total>274552</Total>
  <Config>45862</Config>
</ram>
