The new (v5.8) Vega heatmap and isocontour transform requires "raster grids (matrices)"
input data format as seen in these Vega example data files:

 https://github.com/vega/vega/blob/master/docs/data/volcano.json

It would be helpful to add explanation of this data format in the documentation:

Network component seem to be poorly documented on how to use with Layers, as well as interactivity. My immediate desire is to be able to show some information about a node on hover (or always), such as a label. I can't seem to find anything about this anywhere, and it seems to be a very common use case for this type of data visualization. There isn't much to learn from an unlabeled graph.

This is a feature request for text ... I'd like to be able to write text with only an outer stroke (no inner stroke).

The main issue with the current fillStroke function is that the stroke gets added to the inside of the font, which makes the font skinnier and hard to read at small sizes.

Here is an example of what Konva does (top text is no stroke, bottom is with a stroke)

The curve tool is showing the correct color when the right mouse button is down but switching back to the foreground color once you release.

  • You can still make curves in both colors, since when finalizing it uses the correct color. It's just the preview can be confusing.
  • This was broken in "Make Curve tool passive until finalized" (90493cf687b17df73a2cc37b6db878aa1d204f7a)

发现,如下图绘制两辆小车,点击小车,该小车旁的圈圈会 show,同时其他小车的圈圈会 hide。连续切换点击小车后,会出现圈圈显示无效的问题。

小车代码如下:

var group = new zrender.Group({
        position: [20, (k + 1) * 160]
      }).on('click', function () {
        $.each(containers, function (k, v) {

设置canvas背景色为蓝色.canvas { width: 100%; height: 200px; background:blue; }
设置页面背景色为黑色page{ background-color: rgb(0, 0, 0); }
此时发现wx-charts右边存在一个长方形小区域无法设置颜色(如图中箭头指示区域),依然为白色,柱状图、折线图等带横纵坐标的图表类型均有此现象,而饼图、雷达图等无横纵坐标的图表类型没有影响,是什么原因?

Some people seem to read https://html.spec.whatwg.org/multipage/forms.html#dom-form-nameditem as implying that a new nodelist should be returned each time when there are multiple matching elements. That's not the intent, I assume, and it might be worth clarifying the spec to make it clear.

All browsers I tested (Firefox, Chrome, Safari) return the same nodelist on multiple accesses.

I was trying to look up the API for the DebugPanel so I could locate an option to decrease the text size. I'm developing a smaller resolution game and the elements of the panel overlap and are unreadable/unusable at these lower sizes. Upon opening the API and searching/clicking on the DebugPanel link, I'm routed to [http://melonjs.github.io/melonJS/docs/me.DebugPanel.html](http://melonjs.github.io
