| 21/6/01 Sun Day 2001 |
| 15/5/01 Photo Voltaics - evaluation of 4 panels, and some research |
| 31/12/00 Display Version 2.20 A re-work
of the x-axis time scale logic. Previous versions were limited to 31
days of data. This limit has been removed. The day of the week is now displayed, as well as the date. "Day on Day" traces now clip at midnight boundary. "Power Copy" added. This features eases the tedium of creating solar power reports. Horizontal scrolling now updates the date display. (Use of the STL programming library that's what I'm into. This will make any future port to non Microsoft platforms easier.) |
