It's like a map on your phone: you can look at the whole city or at a single street. The city is the same, but you see different things.
In the simulator there are buttons above the chart: 1D is the last day, 1W is a week, 1M is a month, 3M is three months, 1Y is a year, 5Y is five years, and “All” is the whole history. Over a day the price may be falling, while over a year it's rising. Both charts are right — they're just about different stretches of time.
