I have the data with all colnames but the first one being 'year'

which looks like this:

```
Products      1999   2000   2001   2002   2003  ...

   Rice     23.254  19.42  17.30  10.22   8.05 
   Meat     45.123  30.15   5.33   4.08   1.09
  Metal     60.347  12.48   6.79   4.98   0.86
   ...

```

I would like to plot a graph of each row (separately or all in one graph) against time with x-axis being year (1999, 2000, and so on) and y-axis is the data. For example,

I have searched but couldn't find the way to do this. 
I could rearrange my data in the normal way (with year as a column) but I would like to know whether there is a way to plot a graph with the data being like this. 

Any advice would be highly appreciated. Thank you very much in advance!
