Hello, I have a question to ask, how does canvas get the content in the inserted chart? ![tempsnip](https://us1.discourse-cdn.com/elastic/original/3X/c/f/cfeb3b6c8370b7d4bb4db5bcb9499030094a8c1f.png) As shown below, in canvas, how do I get the ordinate A of this bar graph and apply it to another graph? ---

Chart embedded is a canvas doesn't expose its internals to Canvas. You could however open the chart and see how `A` is being contructed and try to replicate it using available methods for canvas (query to ES, timelion etc) ---
