Column chart in BO4.1

Hi All,

I have few queries on column chart in BO4.1 Webi.

1. Why the bar at the bottom look blur when I change Value Axis scaling as Min "60.0" and Max '"100.0". However, when I keep it 0(min) - 100(max) it looks good with fine border and shape at bottom.

Sorry can not attach screenshot here.

2. How can I set Grid in BO4 for Y axis, the way we can set in BO3.

3. Is there any way I can set tick length to 0, with the options available the min value I can see is 2.

Appreciate inputs!

Thanks!
