The tracking signals computed using past demand history for three different products are as follows. Each product used the same forecasting technique.

TS $1$ TS $2$ TS $3$

$12\mathrm{.}701\mathrm{.}540\mathrm{.}10$

$22\mathrm{.}320\mathrm{.}640\mathrm{.}43$

$31\mathrm{.}702\mathrm{.}051\mathrm{.}08$

$41\mathrm{.}102\mathrm{.}581\mathrm{.}74$

$50\mathrm{.}870\mathrm{.}951\mathrm{.}94$

$60\mathrm{.}051\mathrm{.}232\mathrm{.}24$

$70\mathrm{.}100\mathrm{.}752\mathrm{.}96$

$80\mathrm{.}401\mathrm{.}593\mathrm{.}02$

$91\mathrm{.}500\mathrm{.}473\mathrm{.}54$

$102\mathrm{.}202\mathrm{.}743\mathrm{.}75$

Graph the tracking signals for each forecast and evaluate the movement of the signal. Assume that the analyst would flag forecasts with signals that are greater than $3$ or less than $-3.$

Instructions:

$1.$ Note: Use the line tool to draw the tracking signals $($TS$1,$ TS$2,$ TS$3)$ for each product.

$2.$ Note: To earn full credit for this graph you must plot all required points, beginning with the first unit.

$3.$ Note: To enter exact coordinates, double click on the point and enter the values of x and y$.$
