Interactive Knife Steel Composition Chart
New versions - Knife Steel Chart 4.1 and Graph Builder 3.8 went online today. You will need to clear browser cache in order to get correct new functionality. Normally Shift+click on Reload does the trick, although in some cases you may have to clear browser cache manually.
Mainly user interface updates, fixed settings dialog for the steel chart. All dialog windows are now modal, i.e. prevent users from clicking in the wrong places before completing dialog action. Fixed few bugs in both chart and graph.
Internet Explorer 8 support is officially dropped. For the reasons explained below. It will still work for small charts, i.e. queries that return less than 300 records or so.
Added about two dozen new alloy names, which means more than 5000 alloys in the chart.
NOTE - In the knife steel chart, please use Settings dialog to set default standard to something other than "All" which for now is the default. In other words, as it is, chart loads all 5000 names grouped by compositions, and I really doubt someone needs to look at all 5000 of them at once. Search functionality is quite well developed in the chart, there are menus to access listings by standard, country, maker name or technology. Search itself works against entire database and there are actually 2 types of search, simple and advanced. Given all that, selecting particular standard as a default will greatly improve initial chart loading speed.
For the record, IE8 can't even load complete chart, because of the large number of alloy objects. And I suspect in many cases that is the reason people are not finding alloys like CPM S30V in the chart, trying to dig it up in thousands of names.
Partly it is my fault, in the initial design I never expected 5000+ alloys in the chart.
Let me assure you, default standard setting doesn't affect search capabilities and at any moment you run search against entire database What this settings do is to narrow alloy list from everything in the database to something more manageable when there are no search parameters specified i.e. going directly to - http://zknives.com/knives/steels/steelchart.php
For now, settings allow selection of one of the 17 standards or "All", but in the future I will add settings selections for countries as well, or even makers. This is all very similar to what you have in mobile versions of the steel chart.
Settings are stored in the cookie. If you have them disabled, please make exception for zknives.com.
In the future, I suppose that will be steel chart 5, the users will be reminded to set settings, dialog will pop up and ask the user to make the selection, although even in that case you still can select "All" as default, if your browser can handle it and you are ok with waiting...
Thanks again to everyone who sent new steel info, found bugs and suggested new features.
New versions - Knife Steel Chart 4.5 and Graph Builder 4.0 went online today. You will need to clear browser cache in order to get correct new functionality. Normally Shift+click on Reload does the trick, although in some cases you may have to clear browser cache manually.
Main effort was to improve the performance of the steel chart, and improve keyboard support.
Still, for the full chart performance is low, unless you're using really powerful computer IE9 and IE10 have hard time scrolling and take long time to render full table.
Same advise as before, use settings dialog to set up more manageable setup. Chrome, Opera and Firefox are more or less ok.
Keyboard shortcuts were designed Windows platform, some of them won't work on Macs. I'll see what i can do later on.
