change Font size and display 0 on column chart in Dashboard Studio

[LearningGuy]

Hello,

How do I change the font size on the column chart in the Splunk Dashboard Studio

See below the 170500 is overlapping with 170400. 
How do I display 0 on the column chart?   0 is ignored.
Please suggest. Thank you for your help.

Unfortunately Dashboard Studio does not have an option for this. Are you able to make the visualization wider to make room for the numbers? Or you calculate the numbers into different units to reduce the number of digits.

I can make it wider by reducing the time frame, but last 7 days is usually the default.
Are you sure we can't do it on the CSS part? Thanks
