Currently, only hover over, the axis, or displaying the data source to gives a reference for the values shown in the graphs. Can the graphs have an option to plot the number on the graph so that in print view of the workspace the numbers are visible on the graph itself?
For a reference to the values shown in the graph, the axis values do get shown in the printed version. If you are talking about the values shown when you hover over the point on the graph, that is currently not an option. It would be great if you could create a feature request around it so we can consider it for future release. Go ahead to the ideas exchange and request for this feature.
