@primozs, @Ranjan_Mohapatra, the plugin is called “Usage statistics” and it is under the installed plugins tab!!
So this is very easy, see my screenshot!
Click on “Settings” and then flag the last checkbox (see the following screenshot), “Display submission statistics chart for reader”
What I am trying to figure out, instead, is how to display not only Pdf Downloads, but also the abstract views. Why? Because pdf Download files can be very low, since the people don’t necessarily download PDF but just view them, clearly! So I want to show also abstract views at least, maybe in the sidebar, like in the following example:
About this issue, there are hundred of threads and posts to read here in the forum; I have read that it is needed to add and edit some code (so also creating a Child theme), which in any case my case didn’t work. In my opinion, this would be a feature that should more accessible!
What really frustrates me, is that I see that many journals have implemented issues and solved things without sharing solutions or discussions here on the forum! So their solutions don’t get available for the community.
Please help me back, if you can, on this!
Thank you and best regards,
ps.: maybe @bozana could help with this? Does it exist a definitive, integrated, official solutions for full article metrics on OJS 3.1.2-4 and not only for Pdf Downloads?
