I'm not the world's greatest computer whiz, but I thought that perhaps someone on here might be able to point me in the right direction.

I have kept a bi-weekly record of my weight for the last several years (on calendars) and I want to turn this data into simple line graphs that display one year at a time, two lines, one for the high weight for the week, one for the low weight for the week.

If anybody has any ideas of what sort of program I would use to make such a chart I'd love to hear them.

regards
