Filter button Users allow to choose the filter (toggle menus - Last 4 hours, Last 24 Hours, Yesterday, Last Week and Last Month) and the date range to change the details of a graph (not shown), if user selects or update into a specific date range, the toggle menu filters (as my boss wants) will be off, means deselected - removing a default value. But I don't want to do that, cause it will probably confuse users if the toggle menus means on or off or even disabled. With my other concept where Specific Date Range is part of the toggle menus but it requires 2 actions (choosing Specific Date Range and update the dates), also it doesn't need to autoupdate while Specific Date Range is selected thats why I have a Filter button next to it.
There are 2 reasons of this. 1. It is to guide user that which are the ways to access the information. So that they can search for data accordingly. 2. Listed data are shown based on which parameter. For example, default listing order is in recently first order if default value in drop down is selected so.
So the main aim to show default values is to guide the user and to make it meaningful to the user to use the system or to access the information.
