I have started using the Image-Charts Docs for Bar Charts
Vertically grouped Bars chart works as expected. You can see all 3 Items grouped(see the image below).
But
Using the same data in url for a Vertically stacked shows only 2 Items stacked (see the example from the docs below). Both images attached can be found in the link to documentation
I work with this url to output stacked bar chart, but some Items are not visible/displayed.
