Show historical data in replay mode

When you "replay" historical data, the data is continuously plotted on the chart, starting with the start date. By default, the "replay" mode uses real-time speed. For example, if you set the chart to update every second, the start time advances one second with each update.

You can accelerate or slow down the playback by specifying a "playback speed." For example, if you select a playback speed of 2 x (that is, twice the normal speed) and set the chart to update every second, the start time advances two seconds with each update, as compared to one second for a playback speed of 1 x (normal speed) or half a second for a playback speed of 1/2 x (half the normal speed).

To "replay" historical data

1. Configure a query with a time period whose end time is earlier than the current time.

2. Make sure the Update to Current Time toolbar button is not highlighted. If it is highlighted, click it so that it isn’t highlighted anymore.

3. Click the Live Mode toolbar button.

   The trend curve is dynamically drawn on the chart. The Replay Mode icon appears at the top center of the chart to indicate replay mode.

To "replay" historical data at a slower or faster speed

4. Configure a query with a time period whose end time is earlier than the current time.

5. Make sure the Update to Current Time toolbar button is not highlighted. If it is highlighted, click it so that it isn’t highlighted anymore.

6. Click the downward arrow next to the Live Mode toolbar button. A list of playback speeds appears.

   

7. Click the playback speed you want to use.

8. Click the Live Mode toolbar button.

   The trend curve is dynamically drawn on the chart at the specified speed. The Replay Mode icon and the playback speed appear at the top center of the chart to indicate replay mode. To change the speed while replay mode is active, repeat steps 1 and 2.

Note: When you replay historical data at an accelerated speed, eventually the time period "catches up" with the current time. When that happens, the speed is automatically reset to normal, and the trend effectively goes into live mode. For more information, see Showing Live Data.
