Re: Trouble making bar charts click size accessible

Hi, it is hard to achieve this without making the bars thick. Adding a border to SVG elements (partially) eats into the element, so adding a transparent border usually won't be ideal. Using a scrollable plot area or make the chart container scrollable might be the easiest option: https://jsfiddle.ne...

Re: Need to override the default "region clickable" announcement to screen readers in bar chart

Thanks for testing this. You are right, there is apparently another event added, which is necessary for focus management for the keyboard navigation - where we need to know if the chart received focus through keyboard nav or by mouse click. I could give you a workaround to remove it, but not without...

Re: Need to override the default "region clickable" announcement to screen readers in bar chart

Hi Teodora, This is an unfortunate side effect of how Highcharts handles things like custom click events, zooming, and the navigator in Highcharts Stock. Highcharts attaches a single click/mousedown event on the container and will dispatch custom events to the appropriate internal target. Our "...

Re: Highcharts Sonification Studio feedback thread

Hi psshssas! This thread is specifically about the Highcharts Sonification Studio project, which is a separate thing from the Highcharts development library, and not generally targeting developers. You would be safer sticking to official releases for Highcharts in a live project, but if you test the...

Re: A11Y - Read more than 105 points in chart tooltip

By default we do not enable individual descriptions on points for charts with a lot of data, but this can be configured with the following option: https://api.highcharts.com/highcharts/accessibility.series.pointDescriptionEnabledThreshold. Before Highcharts v8.0.0 the same option could be found unde...

Re: Highcharts accessibility module slows down tooltip marker movement

Hi, I am not experiencing any slowdown on my machine with the dataset you sent over. Which browser and OS are you using?

To remove the marker "trail" (caused by the marker animation), set "series.states.normal.animation" to false: http://jsfiddle.net/jrmqdk10/

Re: Highcharts accessibility module slows down tooltip marker movement

Hi, It looks like your chart configuration is already fairly resource intensive, so you might want to look at using Highstock or the boost module if you are going to display a lot of data. I tried to replicate the configuration in a jsFiddle without React: https://jsfiddle.net/mhfe81dx/1/ How much d...

Re: Accessibility not passing Accessibility Insights for Web

Hi BobJin, This is a good question, and we have considered adding a description to the charts before. We decided not to, based on how screen readers handled SVG at the time. Certain screen reader/browser combinations would read out the description of the SVG for every single data point, which is obv...

Re: Accessibility Keyboard Navigation

Hi, Apologies for the late reply. I'll try to answer your questions in order. 1. The reason for supporting both is simply due to different user patterns. Many keyboard-only users will be using tab by default for navigation, and it will be more intuitive to them. Also, they might not discover the pos...

Re: Lat/Lon misplaced

There seems to be an issue with some of the USA admin2 map projections. It's not yet clear if this is an issue with Proj4js or a problem on our end. For now, there are a few workarounds. 1: Instead of using the Michigan map, use the highest detail country-wide map of USA, and remove the states you d...

Re: In time series chart, on zoom wanted to load detailed po

Highstock will do this automatically, using data grouping, but if you wish to stick with Highcharts you could probably implement something similar by catching the xAxis.afterSetExtremes event and setting data manually using series.setData (http://jsfiddle.net/9hj0gtg3). See this article for a relate...

Re: Using a custom webfont

If you are unable to use script injection, this can be solved by loading the font in custom code and overriding the chart options, as shown in this example: https://cloud.highcharts.com/charts/ywigav
