autoSize is not smooth

[vishnuc]

Please check this video

When resized from right to left its smooth.. but when resized left to right its shaking and not giving smooth effect.

I tried

new ResizeObserver((entries) => {
	if (entries.length === 0 || entries[0].target !== container) {
		return;
	}
	const newRect = entries[0].contentRect;
	chart.applyOptions({ height: newRect.height, width: newRect.width });
}).observe(container);

, also tried autoSize : true option ,

even debounced , but when widht is increased on left side its causing this unpleasent experience.

hi @SlicedSilver , can you check this issue , please watch this video - https://youtu.be/J4hFzGIGR4o

price pane and time pane is jumping when resized and autoSize is set to true ,, its smooth in original tradingview website.. how to keep it fixed and autosize affects only the chart ??

Hey @vishnuc,

I've made a snippet with autoSize and it works fine in both directions.

My initial assumption is:

• It's unrelated to chart itself
• I'm missing some steps

Could you please have a look? Can you reproduce it in isolation?

Hi , check this out - https://stackblitz.com/edit/stackblitz-starters-qp2nbt?file=index.html

when u drag the horizontal bar up and down to resize.. u can see time pane is jumping.. also if resize from left u can see price pane is shaking..

if u cannot reproduce , let me know will share video..It happens same in mac and windows.

@vishnuc Thanks, i've checked you example and this jumping occurs when chart container width is not aligned to fixed value. Charts are pixel perfect by design so they resize in fixed increments while you supplying continues values. Container width of 443.281px resolves to chart width of 442px.

Hi , so what is the solution ? I increase height of container by percentage .. I cannot use pixels......also i tried to use rounded pixels like u said ,, still panes are jumping/shaking.
