Hi, I still dont have any idea how to update bwchart.com, so here is a new version. I fixed a few bugs, added smooth curves, and a new chart called "Map Coverage". It tells you two things:

1-how much percentage of the map you have buildings on (it doesnt care about buildings that were destroyed, of course)
2-how much percentage of the map you are moving units on (moving=move or attack command)

Those curves work on a 8x8 grid placed over the map, whatever the size of the map. So it's a rough percentage, but it's good enough.

The first curve is a growing curve, like resources, because we dont know if buildings were destroyed.

The second curve is more like APM, because we consider unit movements only. To see that curve you need to check the "Units" check box. Also you can set the curve style (flat, dynamic, etc).

It's quite fascinating to see that on some pro replays, guys are sometimes moving units on almost 50% of the map. Considering a lot of the map is not even usable to place units (cliffs, water, rocks, etc), 50% is impressive.

Too bad I dont have my site on to explain how the computation of the curve is working.

Cheers

感谢fyxbear翻译：
各位，（N年后）我仍然不知道如何去升级BWCHART.COM，因此在这里仅给出了一个新版本，增加了平滑APM曲线（分析），以及一个叫“地图覆盖”的表格。它会告诉你两件事情：

1.你的建筑占了地图多少百分比的面积（这不考虑那些已被摧毁的建筑）
2.你的单位的视野探测占了了多少百分比的地图（视野探测=移动或攻击命令）

不论地图的大小怎样，我们以8*8的方格分割地图，这些曲线就是以（你所探测或建造的建筑）所占方格的比例来确定，因此这只是一个大概值，但这已经足够好了。

第一条曲线是一个不断增长的值，如资源那样，因为我们不考虑建筑是否已被摧毁；

第二条曲线更像是APM（就是说会忽高忽低），因为我们只考虑单位的动作。你可以单击“单位”选框去看这条曲线，你也可以设定曲线风格（平滑、曲折等等）

在看一些高手录像时（第二条曲线）是相当迷人的，因为他们有时候会在几乎50%的地图上移动单位（就是说PRO的单位视野占了一半的地图，一般是多线作战或者后期大规模控兵）。考虑到地图上有很多不能放置单位的地形（水、悬崖、岩石等等），50%是很壮观的了。

由于篇幅关系我就不详细介绍曲线的计算机理了。
