A lot has been written in regard to charting capital return and total return.
Such as:

Normal technical analysis is typically performed on capital return charts, not total return charts (e.g. people don't take into account dividends when deciding support/resistance levels).

A total return chart shows both your capital return AND cash dividends/returns.

and
Typically charts used by investor, traders and institutions-alike are capital return charts. i.e. after all adjustments they show the price appreciation of a security excluding any dividends. Which chart would you like to perform your analysis on - your own specialized chart or that used by institutional traders?

Total Return = Capital Return + Income Return
In the case of shares, for example, the change in the share price of a listed company over time can be considered the capital return. If a company’s share price has increased from $10 to $12 over a given year (ignoring share splits or rights issues), then the capital return would have been 20%. If, however, the company also distributed a dividend of $1 at the start of the year, then the income return would have been 10%. In this case, the total return from the share over this period would have been 30%.
