The red bars in the lower graph can represent anything from a single lost sample - to 100% packet loss for a period of time, depending on the scale you're using.<br><br>See <A HREF="http://www.pingplotter.com/forums/showflat.pl?Board=Beta&Number=412" target="_new">the post about packet loss display</A> for more details on how this works. Some red at all means that you've lost at least one packet - which is 100% of the packets sent out that 1 time. Now, it may be that you want to know about a specific period of time. Depending on the scale you're using, that is represented by a red period of some width - the wider, the longer the downtime. If you're normally showing enough samples at once to have it averaging multiple samples, you can change that packet loss percentage scale so that a full-height red bar is 100% (again, see the linked post for some details on this).<br><br>Of more importance, though, is probably setting your "samples to include" for a specific number (ie: if you're doing 1 sample a second, setting "samples to include" to 60 will be one minute), and then double-clicking on the period you're interested in. The upper graph will show the packet loss % for the number of samples you specify - and the "focus rectangle" on the lower graph will move to show which samples you're showing the avg/min/max for. You can then move this focus window (by double-clicking on the lower graph) to see what the percentage is for just that period you want.<br><br>Hopefully, this gives you some additional info on how to tailor and move the display to show your problems to your ISP. Of course, you're welcome to include a link to an image that I can see - and I'll be happy to comment on it to give you some advice on showing the results you want.<br><br>
