Hello, 
I have a problem with the graphs generated by the rrdtool. I'm using RRDtool
1.3.8, and when I select a graph that display valuses for more than 2 days, 
then the values showed are incorrect.

I attach graphs for the next descriptions of the problem, and how i generate
the graphs, also attach the rrd files used to genrate this graphs

this case de graph is incorrect because the max of the graph must be 183 and
