The local lift, usually lowercase $l$ is integrated to form the total lift $L$.
$L=\int_{-b/2}^{b/2} l\,dy$
Just as $L=C_L\, q\, S_{ref}$, $l=c_l\,q\,c$ where $c_l$ (note lower case) is used for 2D and it is multiplied by the local chord.
You might notice that
$S=\int_{-b/2}^{b/2} c\, dy$
So, in the figure above, the chart labeled $C_L$ should have been labeled $c_l$ and the chart labeled 'Lift' should have been labeled $l$. This looks like a chart that may have been correct in its original form, but has been re-made so many times that over time someone didn't understand the importance of lower-case capitalization on those labels.
The reason the $c_l$ and $l$ charts do not look the same is because the chord of those wings varies.
