Whether searching for broker spot rates or shipper contract rates, these slider bars will allow you to select the area and time frame for the rate displayed.  The level of detail you can choose here depends on your RateView subscription.

Simply drag the sliders from one side to the other to increase or decrease both the time frame and the geography to see a different range of rates.

Note:  If you are unable to drag the sliders left, it is due to the fact that DAT does not have enough rates at that level to provide an average.  RateView will always default to the best possible rate in DAT's database, which is indicated by the orange tick marks on 3d and Mkt in the image above.
