It is not industry practice to actually give the sources then? Just list vague names in a short "Sources:Companies" note? I now see the inflation indication as well. Which is not on the y-axis label, but in the "Sources:"-note. I will concede that. But what the hell my guy, why is it down there.
If "financial analysis" is less rigid in sourcing requirements than grade school, what are you guys even doing. If you have the source, it's not very difficult to make a bibliography (or even write the year/publication with the author/publisher), and not doing so only serves to hinder the reader. If this is industry standard it means your entire industry is terrible at sourcing, does not want the reader to verify claims, or both.
And I've also definitely seen financial slide decks with actual sources cited. So I'm inclined to hope there are people in your industry who actually respect the reader's time.
Here's some more picks (and some more reasons you should list your sources): Your graphs based on surveys don't report error margins. You never list what a 100% is very precisely (what's the sample/population). In one graph, you don't label the y-axis at all (except for a 0 at the bottom)!
And finally, I was rude, yes. But I was only matching your energy. And I did show constraint there. I didn't make a veiled threat, did I?
