How to Use Event Window


Event window is the largest window on this interface that located in the left center position. This is where the timeline state diagram display of the data collected will be shown. This screen shows each of the recorded event sequences along its own timeline.

Before you load in any data file, the event window is basically empty. Shown below.

Once you load in a file, you will see it as shown on the screen shot below.

In the center of the event window, you will see a state diagram. On the left side, there are the index ID for each processor. There are no arbitrary limits on the numbering sequences, but they will always display in order, from lowest to highest on the screen. And for each processor, there is a row to show its states/events. On the top and bottom, there are two rules to show you corresponding time scale for a particular data file.

The Event Window is scrollable, both horizontally and vertically in order to allow viewing of the full data set without compressing everything into one window. Use the scroll bars located below and to the right of the Event Window to move the display to the portion of the record you want to view. GistView attempts to scale the event sequence displays in order to fit as many on the screen as possible, but with data files containing many event sequences this isn't always possible.

There are several functionalities that the user can perform in this window.

  1. Events Display.

    Notice the radio button called Events on the Tool Bar. At the start of the program, the default state of this button is selected. So when you load up a log file, all the events in the log file will be drawn on the Event Window, as you can see from above picture. If you deselect the Events button, all the events will disappear. So you can switch back and forth by using this button. Each type of events is represented by a different legend, which is shown in Legend Panel

  2. States Display.

    Notice the radio button called States on the Tool Bar. At the start of the program, the default state of this button is not selected. So when you load up a log file, the states in the log file will NOT be drawn on the Event Window, as you can see from above picture. If you deselect the States button, all the states will appear if there's any defined in the log file. So you can switch back and forth by using this button. Each type of states is represented by a different legend, which is shown in Legend Panel

  4. Zoom In/Out.

    To Zoom In, click the "Zoom In" button on the left side, then click a time point to specify starting point, click at another point to specify ending point, then the event window will rescale the time scale, and zoom in to show up the specified time interval.

    To Zoom out, click the "Zoom Out" button on the left side, then you will see a pop up window to ask by how much you want to zoom out. Specify the number, then click "OK", the event window will zoom out to show the specifies time interval.
