Hi i am using Kibana 8.9.0 and I am creating a vertical bar chart with three categories. I wanted to change the font size of the labels and some of the columns have null/empty values I want to show them in the bar but there is no option of doing it.

Also is there a way to show some line (perhaps dotted ) between bars to differentiate them as I have many categories to show. A line in between every category would allow user to differentiate them

Thank you

Hi @bishnoib,

Do yo have the option to select "Show missing values" when customizing the visualization?

Hi, I was able to solve the null values issue.  
I wanted to ask if it is it possible to change the font size of the X and Y axis values on a Lens Bar Chart?
