Hello bmwork.

From the look of that screenshot, I'd say the chart was added to an element coming either from the theme or from a page builder (Beaver, Elementor, WP Bakery, etc.). Unfortunately the issues like conflicts with third party plugins or themes are always possible due to the nature of WP.

You can probably resolve the issue by using wpDataCharts callbacks. 

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

• All necessary resource are available in charts engines API (depends on which one you use). Every engine has different approach of charts settings. In wpdatachart callbacks you have to adopt those settings to wpdatachart object(you can take a look an example for each engine in our documentation and also in Support help center). Huge number of examples for any area of programming you can find on stackoverflow.com(typing your problem in google and of the end add site:stackoverflow.com and google will search only on that website) and also a lot of resource of examples of chart, chart settings and customization you can find 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.

As for the source code used for generating plugins - they are all being created through wp-content/plugins/wpdatatables/source/class.wpdatachart.php

Best regards.
