Slider issue

[#1]

Hi,

I'm using sliders representing months, one as starting point, one as end point. This is working fine in the desktop client:

Now the same slider in the web application has a tooltip showing numeric values:

How I can I display the slider tooltip to show Months in the tooltip? And is there a way to let the slider only "jump" from Sep to Okt and to Nov (only three positions) and not for each and every day?

Is this a bug?

Thanks.

Anyone? Should I open a case for Qlik?
