Content of the graph and tooltip is not clearly when zoom is set to 400%.

[ashish315]

Expected behaviour

The content available at the tooltip and the graph should be visible properly even the web page is zoomed to 400%. The page should get scrolled as soon as the user navigates to the graph.

Actual behaviour

The content available at tooltip and graph is not visible properly when the system zoom is at 400%. The page didn't get scrolled when the user navigates at the graph.

Pre-Requisites:

1. Go to settings > Select 'System' settings > Display Resolution > Select 1280*768.
2. Go to browser settings > Zoom the page to 400% or 200%

Live demo with steps to reproduce

1. Open the URL: https://www.highcharts.com/demo/line-basic
2. Now, zoom your browser to 400%.
3. Now, navigate to the graph and observe the issue.

Note

Same issue observed when the zoom is at 200%.

Hi Team, is there any update on this bug?

[oysteinmoseng]

Hi @msftedad, do I understand correctly that the issue is the page not scrolling up/down as you navigate within the chart?

[msftedad]

Hi @oysteinmoseng, there are 2 issues and both of them occur when the system zoom is at 400%. Hope this clarifies any doubts.

1. The content available at tooltip and graph is not visible properly when the system zoom is at 400%.
2. The page didn't get scrolled when the user navigates at the graph when the system zoom is at 400%.

@msftedad Thanks, could you clarify what you mean by the first issue?

The content available at tooltip and graph is not visible properly when the system zoom is at 400%

On my system this seems like a scrolling issue only, where the tooltip is not correctly in view - is this what is happening for you as well, or are there additional issues with the content?

@oysteinmoseng

The tooltip content is not visible and the graph is also not visible. Yes, its a scrolling issue but if a horizontal scroll is given to entire page, then it will be failed according to MAS 1.4.10 - reflow.

I see - assigning @marvin19, hope you have capacity to look into this.

From what I gather, if we autoscroll the page correctly as we navigate we should solve both issues.
