No, Bittrex won't show USD on the charts. One option is to find your coin on coinmarketcap.com. You can see your coin's BTC value and dollar value on the chart and if you click the market tab you can see the dollar value specifically at Bittrex.
Unfortunately, this it isn't ideal to switch back and forth and have to corroberate everything so the best thing to do is to just start paying attention to the BTC value. When I learned about "Satoshi's" it got a lot easier to understand.
