I'm using gruff to generate side bar graphs on a ruby program, everything was ok, I use the instance method use_data_label = true to show the label for each bar on the y axis. Now that method is deprecated and no longer works, but the documentation does not say how to do the same thing this method did. https://rubydoc.info/gems/gruff/0.19.0/Gruff/SideBar#label_formatting=-instance_method, does someone know it?
I was looking for a replacement method or a code example that shows how it must be done without using use_data_label, but I did not find anything
