The only meaningful historical record is that of interest rates over the years.
Over 30-50 years companies grow from small acorns to large (or  sometimes scrawny) Oak trees....
The valuation influence of slowly changing interest rates is overshadowed by intrinsic growth,divestitures,bad/good news.
This "data" you demand simply is not really  available.
If you had a company that paid a flat 5% dividend,never grew,never issued new shares....same profit,etc etc....you could do a comparison.You would see that it traded as a ? 4 year bond with a 5% coupon.
When GoC 5 is 5% its worth $500....(par)
at GoC  1%  $1000
at GoC 8%  $150
Your failure to understand the bond market is hampering your assessment of these "bond like" equities....
ENB for example is growing....but so is its debt and # of shares....EPS is flat.
Net/net its (currently) a fixed rate bond.
