Hello Jens,
If you set the minValue of the rangeSelector to the first day of a month, grid lines will be drawn at the beginning of months.
The snapToTicks functionality is not available to the chart range selector, unfortunately.
As for the its documentation – we will add it as soon as possible, but in the meantime, here is a list of the supported rangeSelector properties:
renderTo
position
dataField
serieType
size
baseUnit
unitInterval
minValue
maxValue
gridLines
labels
padding
title
description
titlePadding
colorScheme
backgroundColor
backgroundImage
showBorderLine
borderLineWidth
borderLineColor
rtl
greyScale
Most of these properties are the same as the main chart’s.
Best Regards,
