Qimera Time Series Editor Dock


Qimera - Time Series Editor

The Time Series Editor Window is used to display all relevant time series data for the currently selected item in the Source Files Panel.  This data was extracted during the initial import of the source file and is stored inside the Qimera project under the Metadata folder for the line.  As you move your cursor over the data, the current time and value are displayed in the lower left corner of the panel.  Control of the display is managed by the toolbar shown below.  Any edits that are performed and saved in this window will trigger a reaction from the Dynamic Workflow engine.


The time-series editor is not only an editor, it can be used as a quality assurance tool to verify consistency in measurements between two or more instruments because it plots the measurements from all sensors associated with the particular source item.  For example, if you have a source file with two motion sensors, the data from both sensors is displayed simultaneously.  The various types of measurements shown in this editor will update with changes to the associated sensor in the Qimera Vessel Editor.  This includes the sensor's sign conventions (e.g. heave positive up versus heave positive down), sensor latency and also the sensor bias or calibration offset.  This allows you to verify that measurements are consistent across a variety of sensors: If sensors are providing inconsistent measurements, then you'll immediately be able to see this in the time-series plots.  If you decide to correct the configuration in the Qimera Vessel Editor, you'll see the plot update immediately after you save your changes and you will be able to confirm the validity of the sensor configuration change.

Toolbar

Combo Boxes

The first combo box is used to change the specific attribute.   Examples of attributes are X/Y position, roll, pitch, height, heading, heave, tide, standard deviations etc.  The second combo box selects the specific source of the attribute as some attributes can come from multiple redundant sources on the vessel. If you have multiple sources, the currently selected source will be drawn in blue.  The other sources will be drawn in gray.


  Save Button

This will save any edits done to the time series.  Again, saving edits will trigger a reaction from the Dynamic Workflow engine.


  Zoom Out Button

If you have zoomed into an area of the plot, this button will zoom out to the extents of the currently viewed attribute.  The other attributes time axis will also match.


  Explore Mode

This is the primary exploration mode of the tool.  As you move your cursor over the plot, the label in the lower left of the window will update to show the current value.  Also, a tracking ball will follow the location in time along the currently selected track in the 4D View.

  Zoom Mode

When in zoom mode, simply click and drag an area of the plot to zoom into.  Or simply single click a location to zoom in a bit on it.  Alt-click a location to zoom out a bit.  Or hit the Home button to return to the full extents of the data.  At any time, you can Shift-Click to drag the plot to a new location.  This is especially useful when you are zoomed in.  You can always undo an edit using the Undo button.  Once you are satisfied with your edits, you must press the Save button.

 Interpolation Edit Mode 

If you Click-Drag a selection of the time series, Qimera will flag the selected samples invalid and interpolate across the selection using the sample on either side of the selected area.  During processing, time series data queries will then use these new interpolated values.  This is a simple way to get rid of spikes in your data. The invalidated data will still display as a gray portion of the time series.  The interpolated part of the time series will show as a continuation of the blue time series line.  You can always undo an edit using the Undo button.  Once you are satisfied with your edits, you must press the Save button.










Interpolate Mode Selection

 Invalidate Edit Mode

If you Click-Drag a selection of the time series, Qimera will flag the selected samples invalid and unusable.  During processing, time series data queries to this time range will use secondary or tertiary sources of the data when available.  For example, if you have 2 sources of heading and mark a portion of your primary heading data as invalid, Qimera will get heading from the secondary source of this data if available and if the Use Redundant Systems option is enabled in the Preferences dialog.  If not available, Qimera will indicate to the processing engine that this data is not available and if required, the ping will not be processed for that .  This is a simple way of interleaving higher quality data from a secondary source. The rejected data will display as a red portion of the time series.  You can always undo an edit using the Undo button.  Once you are satisfied with your edits, you must press the Save button.










Reject Mode Selection

 Validate Edit Mode

 This mode is an easy way to bring back data that you have marked as rejected or for interpolation.  Simply Click-Drag a selection over the previous edit and Qimera will restore the original data.  You can always undo an edit using the Undo button.  Once you are satisfied with your edits, you must press the Save button.










Validate Mode Selection

  Undo Button 

This will undo the last edit actions.  It is a pseudo-infinite undo buffer (c'mon, how much memory do you have?) in that you can make several edits in sequence and then undo those edits in the reverse sequence. 


  Time Series Plot Menu

Show Height at COG

This setting only affects the display of the Height attribute. When enabled the Height plot will be transformed to the (0.0, 0.0, 0.0) location on the vessel, also referred to as the nominal center of gravity (COG). When disable the Height plot will be shown at the location reported by each system, often the antenna location or INS reference location.

Line Plot

This is the standard display mode for the time series plot window.  Data is interpolated over the selected time range.


Point Plot

This display mode plots only the actual sample values in the time series.  This allows you to see the difference in the update rate of various sources.


Bar Plot

This display mode is pretty much eye-candy but does allow you to more easily see gaps in the time series data.   If your data is bi-polar in nature, the negative values will appear in a lighter shade of blue so you can more easily see the transitions.


Export to ASCII

This options allows exporting the Time Series Plot data as an ASCII (.txt) formatted file containing Date, Time and the selected source data. 


Save to Image

This option allows saving of the current Time Series Plot in .png image format.


Show Grid Lines

This option will disable the gird lines on the current plot.
