I would like to plot multiple lists. The table looks like

```
a={{1,2,3,0,0,0,0,0,0},{1,2,3,0,0,1,0,0,0},{1,2,3,0,0,0,2,0,0},...,{1,2,3,0,0,0,0,3,0}}

```

I want to plot the elements from 4 to end with index\*step as x-axis. For the first line

```
ListPlot[{# step,a[[1,#]]}& /@ Range[4, Length[a[[1]]]

```

If I would like to plot all the rows in the same plot, looks I have to change the a[[1,#]] to a[[#2,#]] and map again with Range[Length[a]]

How could I do that?
