Hello Simon Allport,
By default all series begin from 1 and not from 0 along the X axis, unless you have defined XValue or XCategory to be 0. You can find a sample Line chart in our demo examples
. Simply navigate to Chart ->
-> Gallery -> Line.
As for the gridlines, you can switch them on and off, depending on your scenario. An example demonstrating how to do this is in our demo page, under Chart -> Features -> Flexible API.
