Did you have time to check it yet?

Hi, sorry to be late. I’m spending time for other issue, after finishing that I’ll be into for this :)

For resize, internally is binded resize event to window.

Then when resize happens, it flows:
→ onresize callback (if option is set) → .flush() → onresized callback (if option is set)

This issue is related with the #155 and need to look more detail on .flush() API.
I'll dig into it, and will comment again when there's an update.

For size adjustment, it try to get its parent node width value.
To get that, it uses:

• element.getBoundingClientRect().width or
• element.offsetWidth in case of error.

billboard.js/src/internals/size.js

Lines 88 to 99 in a9a1e09

	getParentRectValue(key) {
	let parent = this.selectChart.node();
	let v;
	while (parent && parent.tagName !== "BODY") {
	try {
	v = parent.getBoundingClientRect()[key];
	} catch (e) {
	if (key === "width") {
	// In IE in certain cases getBoundingClientRect
	// will cause an "unspecified error"
	v = parent.offsetWidth;

But, figure out that in some cases(like this one), it's returning wrong value.
window.innerWidth is smaller than the value which was retrived.

So, for that circumstances, will be updated to use window.innerWidth instead.

@ForsakenHarmony, for resizing it takes from the bound element's parent's width value.

At the initialization, it will take the current width value of the rendered element.
So, in this case will get the correct width, but when chart is rendered, the parent will remain same width as chart's width, because the chart width will remain same as before without changing.

To fulfill with your need, add additional CSS style width property value on each column.

.column{width:50%}

And will work as below.
