By default rrdtool will display the last 24 hours of data. Presuming you have the additional RRA's defined (or have data covering the time period), you'll need to use the Time Range arguments as documented at http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/doc/rrdgraph.en.html

For example, to graph the last 48 hours you might use something like the following --

rrdtool graph $GIFPAL --start end-2d --end now DEF:ccpal=$RRD:ccpal:AVERAGE AREA:ccpal#00b871s
rrdtool graph $GIFPEN --start end-2d --end now DEF:ctpen=$RRD:ctpen:AVERAGE AREA:ctpen#00b871s
