Hello Randal

I'm not sure what you mean by "A bar might be there, but no wording" - like an empty label?

Please provide me a temporary WP-admin login for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course we do not provide login data to third party. You can write credentials here just check Private Reply so nobody can see them except us.

Also, please make sure to tell me what are the table and chart IDs, so I know where to look.

Hi Randal,

Sorry for late response. 

We are located in Serbia and our working time is from 10:00 to 17:00 CET. business days.

Aleksandar have day-off today so will help you out. 

Yes that is the default behavioral of the charts if you have many data they will try to show as much as the can based on default charts settings for labels. 

That is default behavior of charts engine, but if you need some custom solution (overwrite default charts settings) you can check in our documentation about wpDataCharts callbacks. 

• Every chart exposes several options that customize its look and feel. Charts usually support custom options appropriate to that visualization. wpDataChart callbacks allow adding options that are available in Google Charts API, Highcharts API and Chart.js API. 

• All necessary resources are available in charts engines API (depends on which one you use). Every engine has a different approach to chart settings. In wpDataChart callbacks you have to adopt those settings to the wpDataChart object (you can take a look at examples for each engine in our documentation, and also in Support help center). Huge number of examples for any area of programming can be found on stackoverflow.com (typing your problem in google and at the end add "site: stackoverflow.com" and google will search only that website). Also, a lot of examples of charts, chart settings and customization can be found on jsffidle.net (typing in google for example "line chart highcharts jsffidle")
• Please note that using hooks or wpdatatable and wpDataChart callbacks requires certain level of programming skills and included support refers only to advice.

You can check some solutions for pie chart here (changing padding for example) , and for line chart you can check here (changing autoRotation for example)
