The log file must have data for the graph to use. The ignore zero settings option suppresses settings where the time was in sync and displays settings (in 3D) where a time change was made on the local computer. Data is displayed from the last setting made on the previous run of ClockWatch backward toward the first setting. Increasing the number of data points shows earlier data if available. Clock Drift Graph -The Clock Drift chart shows the amount of drift between two successive settings where the internal system clock was changed. Drift is an indication of how accurate the system clock is over time. -The vertical axis shows the clock drift (in seconds per day) which is calculated using successive settings where the internal clock was adjusted. Settings where there is no time change are ignored for the drift calculation. For these "0" settings the drift is shown as "0". The horizontal axis shows the time settings - the date or time of the actual setting is shown across the bottom of the graph. Notes on the Graphs -The horizontal axis for charts is the date and time the settings were attempted.. Settings where the system clock was within 1 second of standard will show as setting with no time difference and no clock drift. -The number of data points will show the most recent data only when the number of settings in the current session exceeds the number of data points. -Graphs will only display after there is at least one new setting to display. -When restarting the program, the first value on the chart will be the last setting where a time change was made. -The previous settings graph shows data in 3D when the Ignore Zero option is used, in 2D when zero data is included. -The vertical scales (y-axis) scale automatically depending on the maximum value to display. -Selecting a graph with the mouse will open the Graph Options tab. Upon redraw, the selected graph will then be in the leftmost position of the graph area of the main screen.
