how can i create a chart that for the values that start say for example from
0 for a speed of 1000 and then revolve through different values of speed.
these values values when plotted initially start from 0 for 1000 and reach a
highest value at say 4000 and return back to 0 at 1000 speed. say that values
if they look like these,
1000 0
1400 7
1500 680000
1800 0
2000 650000
2500 660000
3000 750000
3100 800000
3400 0
3500 0
