I have some xls files that contain a several graphs that are generated from thousands of data points.

• Open Office takes 10 minutes or more to open them.
• Gnumeric opens them quickly but doesn't draw the graphs correctly.
• KSpread doesn't draw the graphs.

However, I just tried the trial version of PlanMaker for LInux and it had no trouble displaying the graphs exactly as they should and was able to open even the largest file in just a few seconds.

Horay for a viable alternative, even if it is not open source.

Wow! That is so cool that you were actually there to measure the length of a day! So, like, you've got a really good pension plan, right? Do you still have the same clock?

Or is this just more uniformitarian assumptions masquerading as science?
