Custom field to chart value?

Hi there,

I’m using visual composer to build a product template page that will be used for many products. Each product has a few charts that describe the ratios of the contents of their mixture. These values are defined in custom fields and the charts will be uniform throughout the templates, so I’m trying to see if I can somehow add a custom field to the value of a chart so that the charts are built automatically for each product. Is there a way to do this with this plugin?
