keyboard accessibility issues in Stacked Bar

[Rafal Gleba]

Hello.

I need to use the chart via the keyboard, but I have found two issues that I don't know how to solve.

1) Tooltip - Wrong tooltip is displayed when navigating with the keyboard between bars

2) Bar with value "0" - When a bar has a value of 0, I would like it to be skipped. Currently there is a focus with an empty bar

Is it possible to solve these two problems in the current version?

Hi Rafal,

Greetings from Syncfusion.

Query1: Tooltip - Wrong tooltip is displayed when navigating with the keyboard between bars

We have considered your reported scenario as bug and logged a defect report for this issue.

You can keep track of the bug from the below feedback link.

Query2:  Bar with value "0" - When a bar has a value of 0, I would like it to be skipped. Currently there is a focus with an empty bar

Currently, the default behavior of the chart during keyboard navigation does not skip data points where the y value is 0. When navigating through the chart using the keyboard, the focus will move through all data points, including those with a y value of 0.

Kindly revert us if you have any concerns.

Nishanthi
