Dear All,  
I'm trying to create a bar chart where the bars' bottom points may be different from 0. [This](https://www.chartjs.org/docs/latest/charts/bar.html) article (if I understood it correctly) suggests that it might be possible with Charts.js by giving the "data" array like this `data: [[5,6], [-3,-6]]`, but when I try to do that in Node-Red, what I get are the bars starting at 0 and ending at the first elements of the arrays.  
Is it possible at all to create such kind of barchart with Node-Red?  
Thanks in advance!
