In charts, date grid does not reflect weekstart setting
We have a date field that contains weekly values, always the Monday of a week. If I use the automatic scaling for the date field, the grid starts always on 1st of a month, but when the total period gets shorter and the grid switches to week granularity, the grid line is always on Sundays. I already changed the weekstart variable in the script to '0' for monday, but the scale line is always on Sunday.
Any idea how to make the grid show the Monday-date?
