Filtered Data vs. Selected Data

Filtered Data vs. Selected Data

Within GlyphViewer, there are two options for bringing up underlying data to either a) save as a traditional Excel fie, or b) visualize that specific subset of data – selected data, or filtered data.  Selected Data refers to all the underlying data associated with the glyphs you have clicked on (selected) in the Visualization pane.  Filtered Data refers to all the underlying data associated with the qualifying glyph(s) / element(s) after you have applied a filter / filters in the Filtering pane. 



To view selected data, first click on (or otherwise select) the desired glyph elements.  You can select multiple objects in two ways:

1) CTRL + left-click to select multiple objects, or

2) SHIFT + drag mouse to draw a bounding box and select all objects inside the box (see example below). 

After multiple objects are selected, all objects still remain visible in the Visualization pane, and the selected object(s) are denoted by the flashing yellow halo effect.  

Note: In the examples below, three objects have been selected using method 1.



Click on “Show Selected Data”

Note: This option is grayed-out / not selectable until at least one object has been selected. 



A new window will pop up displaying all the underlying data associated with that element(s), as found in the source data file.  The column headers from the source data file are retained. 



From this window, you can export the displayed data to a CSV file (1, below), or create a new visualization that displays only the selected data (2, below). 

Note: Performing the latter action will generate a new .sdt file.  Loading this visualization allows you to directly open this view of the data without having to open the original visualization and select the same objects each time.

Clicking on Create Visualization (2) will bring up a window allowing you to name and save the visualization file.  Once saved, the visualization will open in a new instance of GlyphViewer.



To view filtered data, first apply a filter / filters in the Filtering pane – from the Elastic filters, Range filters, and / or Keyword filters tabs. 

Note: When a filter is applied, the default setting in GlyphViewer is to hide the objects that do not meet the filtering criteria.  To change this setting so that all objects remain visible whether or not they meet the filtering criteria, un-check “Hide Filtered” at the top left of the Filtering pane or in the Main Toolbar.



Next, click on “Show Filtered Data”.  A new window will pop up displaying all the underlying data associated with the filtered objects, as found in the source data file.  The column headers from the source data file are retained. 



From this window, you can export the displayed data to a CSV file (1, below), or create a new visualization depicting only the filtered data (2, below). 

Note: Performing the latter action will generate a new .sdt file.  Loading that visualization allows you to directly open this view of the data without having to open the original visualization and apply the same filter(s) each time.

Clicking on Create Visualization (2) will bring up a window allowing you to name and save the visualization file.  Once saved, the visualization will open in a new instance of GlyphViewer.



To reset the original visualization to the complete view after you have applied filters, click on “Clear All Filters” at the top of the Filtering pane.
