As most charts with some historical data cannot be reasonably displayed in detail as a whole on the computer screen, the most current data is shown by default. You can scroll to display older data with the scrollbar at the bottom of the chart window.
If you want to see more details for a specific section of a chart, you can zoom into a section of a chart, based on a certain date / time range, a number of bars or manual selection. You can also scale the time series to the screen, so that you can see a wider or narrower price range (vertical scaling), or expand / compress the time scale (horizontal scaling).
To quickly jump to certain points in a bigger chart, you can define bookmarks at certain points in time and use them for chart navigation. To quickly jump to the beginning or end of a chart, click the Data View button and choose the option Chart beginning or Chart end. The Data View button is located in the lower right corner of every chart and offers several useful options to zoom and navigate a chart.
If you have many symbols and/or other chart objects, like drawing objects or studies, that should be displayed in one chart document, you can organize them into several panes. A chart pane is a section of a chart that holds symbols, studies and other objects. Every chart consists of at least one chart pane. You can also define several sheets in a chart to organize its content. Chart sheets can also be used in combination with the chart window split to for example display several data compressions in one chart at once.
