In the above diagram :$CC=$ Consumption function$OI=45^{\circ}$ degree line showing income drawn from the origin $O$.$B=$ Breakeven point where consumption = income, i.e, a point where there is no saving.Following are the steps used in drawing saving curve from consumption function :(i) Take a point $B$ on consumption curve and from it draw a perpendicular on $X$-axis intersecting it on point $B_1$.(ii) Take OS on $Y$-axis of lower part as equal to $\mathrm{O C(O S=O C)}$. This gives point $S$ from where saving curve will start.(iii)Join points $S$ and $B_1$ and extend the straight line upward and thus we get saving curve $SS_1$.In this way, saving curve is diagrammatically drawn from consumption curve.
