Major functionality upgrades this week. Added column manager to the steel composition chart. Column manager is invoked from the chart tool bar, Columns button, or you can also use ALT+C from keyboard, depends on the browser though. From there you can hide/show chart columns. You can also hide column by CTRL+click on the column header. Added result caching for the steel composition analyzer graph.

AISI 1018 low carbon steel added. I don't think i's is used by itself, but often used in pattern weldd damascus.

This time this is AISI 1085 steel. High carbon pring steel, so far I have confirmed info about at least one custom maker using it. Posting inquiry on knife forums helped to get that info.

AISI 1044 steel. Strange as it is, or may be not, but this relatively low carbon steel is also used in knives, specifically in throwing knives where toughness is more critical and you don't want to spend too much money too.

Phew. That was more complicated than I thought... As usual :) Anyway, client side scripting is up. Testes successfully on MSIE 7 and 8, FF 3.x, Chrome and Kmeleon. Added caching for the main table view, i.e. no query params except sort. Later I'll add server side caching to avoid db queries for static data and cache move chart views.

Client side sorting is 100% completed. Even found a bug today and fixed it too. However, caching properly is a problem and still struggling with the algorithm. There are several levels of caching involved to make matters more interesting...

It's yet another speed modification for the chart. Sorting currently is done on the server side, and reloading the whole table, issuing query, processing data from 3 tables... Client side sort will eliminate all that and will only take fraction of a second. Sorting is done. I have to deal with the sort indicators and other minor issues and it'll be up. Hopefully tomorrow. May be that will allow for at least some caching too.
