For Chart category, can't change font size, screen reader Narrator or JAWS can't read them.

[Ming]

Developed with Insights Enterprise v2023.2, for the categories in following chart, any way to change the font size?

Based on the official documentation, it is accessible but tried both screen reader Narrator and JAWS none of them can read out the categories.

Thanks for any help!

@Ming Thanks for the question. Unfortunately, there isn't a way to change the font on categories. 

I was able to use Windows Narrator successfully on a Stacked bar chart using Win10 & Google Chrome. you want to use keyboard navigation ("Tab") button to navigate to a category and highlight. Let me know what browser and OS you are using and I can see if there is an issue.

Hi @AkshayHarshe,

Thank you very much for the response. I am also using Win10 & Google Chrome, but the Narrator reads all the chart  as "Heading level one" not the category name like the select bar that should be read out as "Clam".

@Ming I don't hear that, For me it says the Category name. e.g. In my example, it says "<#> Wednesday Menu item"

I am using a newer update to Windows that yours, Maybe Narrator has some updates? See if you can download updates online. 

This is my Chrome version 

Let me know.

Thank you @AkshayHarshe,

Can you please try following one that I used to test?

Then we can confirm it is caused by my OS/Chrome version or chart settings.

Thanks,

@Ming Not sure what is going on with the page you shared, I can't even tab to the category Like I was able to in mine, Here is something I created https://insights.arcgis.com/#/view/7b1cf10f582e4b38ab19bf22bb3fd238 

See if you can navigate to the column and hear correctly. 

Let me know the following e.g.

1. what is the data source used? (Feature service/ excel/ one drive etc.)
2. What tools you have executed? (I see that in the model and I tried recreating something similar)
3. When was the workbook created?
   1. It is possible if the workbook was created before we fixed some things then it could explain the difference. Also, try using a new workbook.

Thank you @AkshayHarshe 

The data source is csv. I did more test, looks it is related to the category count.

This one has 16 categories, it can read out category names:

This one has 23 categories, then can't read out category names:

https://insights.arcgis.com/#/view/e44a70dfc3a04d47a086aeafa6dd3508

Same data source, same environment, same operation.

Maybe the threshold of the category count is 20? 

I will also do further test.

Thanks,

Ming

@Ming  I appreciate you doing the testing and narrowing it down! I can reproduce this.

I am not familiar with VPAT support but it seems like this could be by design and if the number of categories exceeds a certain number then it skips the narration. This is probably to avoid getting stuck on the card for a long time. It also happens to Scatterplots. 

When I navigate to the Stack chart narrator does say "<chart type> chart, visual aid required". 

I will confirm with someone on our team.

Hi @AkshayHarshe,

Just follow up, any update on this problem? Thanks.

@Ming From the information I got, this is handled by the charting library we use. So apparently 20 seems to be a limit but I couldn't find that in the documentation. Unfortunately, this doesn't help you much but it is something out of our control as well.
