I’m not going to echo the overall sentiment of this forum and tell you that graphs and charts are a poor tool for decision making, however I will recommend that you search the forum first to see that’s not something that’s on Manager’s roadmap, and they have some valid reasons for that.
That aside, Manager has an open and friendly API which you can link with the BI solution of your choice.
Several forum members swear by n8n but I haven’t tried it yet. Also, you can link it with MS Power BI or even with Excel.
Check this post out.
