Any advice on making a LAP Chart please?

[JerryK]

We see it on TV screens in motor races, for example.

Down the left Y-axis is a list of drivers in starting-grid order, with 1st place (pole position) at the top at X=0, Y=1. 

I guess there will be a Y2 axis with simply position numbers, again 1 is at the top.

Lap numbers are along the X-axis.

Each car's progress through the race is mapped with a line showing their position at the end of each lap.

Each car could have his own colour/marker.

Hanged if I can see how to do all of that.

Thanks people

Jerry

Hi Jerry,

Basically, you would just use a datatable with one row per time step, and the first column would just be the time steps. All the rest of the columns for a row would represent each of the pole positions, 1 through N, for N positions.  Each column would represent one driver.  If you use a LineChart, this would give you the right chart except for labeling.  If you get that far, then I can help you with how to change the labeling.

Thanks Daniel

It didn't seem that straightforward but I'll give it a go when I next have some time.
