Tell me that you don't know what you are talking about without telling me you don't know what you are talking about.
That is a BS graph, and is merely NASA recycling flawed IPCC modelling of variations in solar flux, and certainly not independently determined .
The reason that IPCC assessment is under criticism because the TSI variation used in its modelling (0.19W/m^2) is only a fraction of the median variance of 1.77 W/m^2 , and is even well below the lowest level of the range of estimates made (0.49 W/m^2 to 4.64W/m^2), and correlates poorly with what has been benchmark TSI data, namely H1993 Solar, complied by widely cited astrophysicists [*]:
