Data View Module
Explore wave data and results in an interactive data visualization environment
Data View is a versatile data plotting and exploration tool for visualizing raw imported and processed data. Features include 10 different page layout options with 1 to 6 plots per page and several different Plot Libraries to select from. As your data analysis proceeds, the number of display options in Data View increases. Image and movie-file export capability is included.
As described below, Data View features are accessible through a variety of interactive plot features, toolbar commands, and pull-down menu commands.
Data View Interactive Plot Features
Plot Menu – Right-Click on a plot title to access the menu for that axes. All the available plots for the current data are available here as well as a variety of display options (described below).
Note: As data processing proceeds, additional plot options will become available. See Plot Libraries for a list of available plots.
Record Scrolling – The scroll bar at the bottom of the Data View window allows the user to scroll forward and back through the data records. A dashed vertical red line will appear in all time-series plot to identify the time of the currently active record.
Record List – Right clicking anywhere in Data View will bring up a menu of plot commands that includes “View Record List”. This opens a Record List window that provides additional user controls for exploring data. Specific controls for the Record List include:
Up Arrow: View Next Record
Right Arrow: Same as Up Arrow
Down Arrow: View Previous Record
Left Arrow: Same as Down Arrow
Page Up: View Next Record Section if Time Axis is Zoomed in
Page Down: View Previous Section if Time Axis is Zoomed in
Home: View First Record
End: View Last Record
Insert: Open Record List
Backspace: Close Record List
1 - 9 : Change Plot Layout to #1-9
0: Change Plot Layout to #10
View button – Time series plots zoom into display only selected records.
View All button – Time series plots display all records
Select Record Using Time Series Plot – See Time Axis Mouse Control in the Options pull-down menu below.
Rotate 3D Plots Using Mouse – Left Click the left or right side of a 3D plot to rotate clockwise or counter clockwise, Shift + Left Click (or Right + Left Click) the top or bottom of a 3D plot to rotate up or down.
Data View Toolbar Commands
A toolbar across the top of the plot page has the following click-tools. Simply click on each toolbar icon to activate the command.
Data View Pull-Down Menu Commands
File Menu – for loading and saving data, plots and movies
Module – Select module to launch
Note: If the current parameters are already in the parameters database then they will save automatically. If parameters exist under the same name a prompt will appear to confirm to replace them.
- Spectra Plots – Default layout for unprocessed data
- Wave System Plots – Default layout for processed data
- Climatology Spectra Plots – Default Climatology layout for unprocessed data
- Climatology Wave System Plots – Default Climatology layout for processed data
The plots that are available depend on the data in each file. The current data and the comparison data must both contain Wave Systems and wind information in order for those plots to be viewed. See Plot Libraries for details.
The Input Data and the Wave System Data plots can also be selected for either the current or the comparison data.
• Saved Layouts- User-defined page layouts. Save custom page layouts by name and recall them through this menu command.
Module Toolbar Commands
In addition to the Module drop down menu, each module can be quickly accessed by clicking the corresponding toolbar icon.
Exporting the plots shown in DataView is simple. From the File menu, select Export -> Image and select from one of the image file formats
The following image formats are available:
JPEG JPEG image
PNG Portable Network Graphics
FIG Matlab FIG file
BMP Windows bitmap
EMF Enhanced metafile
TIF TIFF image, compressed
EPS EPS Level 3 Black and White
Changing the Image Resolution
The resolution can be changed in the Settings menu. Mouse over the Export Figure Resolution setting and choose between ‘Low’ and ‘High’.
It is also possible to create animations (AVI) from within DataView. From the File menu, choose Export -> Movie, and DataView will step through ALL of the records in the current file and export plots in the current DataView Layout. This can be memory extensive so it may be necessary to subset the processed file before creating the animation. Once the animation is complete a save dialog will appear. Choose a location to save the newly created AVI file.
** Make sure the DataView Window stays on top during the animation process because the animation image capturing is similar to a screen shot.
The Data View Module offers a variety of plot libraries to aid in the interpretation and analysis of user wave data. As data processing proceeds new plot types become available to the user. A summary of the various libraries and plot types available with each processing step appears below.
Input Data Plot Library
