We were cleared to descend via the HYPER 6 arrival into IAD (Dulles). During descent we briefed the arrival. We descended to cross HYPER at 10000 as depicted. Approach said to disregard the speed restriction of 250 kts at HYPER. During the arrival we were working with the radar to look at weather near the airport so we were a little distracted. We were also fatigued because of the late hour and a longer than expected flight day. As we were flying along at 10000 feet; Approach told us that we missed our crossing restriction of 7000 at SIGME. He instructed us to start our descent to make the next restriction of MOWAT at 5000; which we did. We did not see these restrictions because it is a separate insert. Sometimes these restrictions vary due to landing on different runways. When we briefed 10000 feet as the bottom altitude on the arrival; we did not notice the tiny note to see the insert for further instruction; thus missing the other crossing instructions. Other contributing factor is that we were using electronic charts and on the larger plates; the pilot has to scroll around to make sure he doesn't miss something that happened here. Sometimes the pilot has to search for another chart that has a text description of the star. This all adds to workload; especially when you have other things going on like using the radar to get around weather. We both learned that while using electronic charts that you have to scroll around the entire page to make sure you don't miss something. Also you have to make sure that you don't miss small notes on seeing other pages or inserts.I do wish; however; that the charts were easier to read during high workload situations and that you don't have to search around for different inserts or pages. We have noticed that sometimes on charts; particularly on SIDs that the basic relevant information has to be searched for. For example; the basic things a pilot has to comply with are navigation (if not on a vector); altitude and speed. We have seen cases where these three items are scattered on a navigation plate instead of being centrally located for easy depicted information of what the procedure calls for. We have seen Speed restrictions in different locations on plates for different airports. Why not make it standard that the three basic instructions (navigation; altitude and speed) are all in one convenient location. I sometimes wonder as these procedures become more complex that if the procedure is not easily deciphered; it could set the pilot up to miss something. We learned our lesson that you have to make sure you don't miss something on these procedures. We also wish that the procedures sometimes are better disseminated.
