I typically just upload the file to cross country.aero. You can see the map and bariogram of your flight plus go through the igc file point by point.. Helpful when trying to figure the min and max altitudes for the altitude leg of a badge.

As you probably know but it might be worth reminding, there's quite a good deal of data available to you when you upload your flight (within 48 hours) on OLC (www.onlinecontest.org) and it's even free. Also, www.glideport.aero is a good source of free flight analysis.

If you want to do any kind of detailed analysis, SeeYou is the only serious tool. It comes with Oudie flight computers or can be bought via a permanent license (~$170) or through an annual subscription for ~$60/year.

Hope this helps.
