Zen,
Assuming the data label "A" resides in cell A1, you can set up a simple
sawtooth pattern by using an XY Scatter chart with your data set up as
follows:
A B C D Y
1,000 5,000 5,000 9,000 0.5
1,000 4,000 5,000 8,000 1.5
1,000 3,000 5,000 7,000 2.5
1,000 2,000 5,000 6,000 3.5
1,000 1,000 5,000 5,000 4.5
Assume the sheet name is "st". Create an XY Scatter chart.
The first series is a vertical line . . .
The X values are:
=st!$A$2:$A$6
The Y values are:
=st!$E$2:$E$6
The second series is a diagonal line . . .
The X values are:
=st!$B$2:$B$6
The Y values are:
=st!$E$2:$E$6
The third series is a vertical line . . .
The X values are:
=st!$C$2:$C$6
The Y values are:
=st!$E$2:$E$6
The fourth series is a diagonal line . . .
The X values are:
=st!$D$2:$D$6
The Y values are:
=st!$E$2:$E$6
And so on . . .
Given this logic, you should be able to set up an XY chart to show inventory
additions, consumption, and trigger points for reordering.
