Screenshots¶

The following screenshots show several different elements of the user interface.

Initial Default Appearance¶

The default appearance uses OpenStreetMap as a basemap, black open triangles as location markers, and red wedges (inverted triangles) to mark selected locations.

Plots and Column Data Types and Completeness¶

Two different types of plots (a scatter plot and an empirical CDF plot), and a table of data types and statistics, are shown on top of the default user interface. Several locations have been selected and are highlighted on the map and in the data table.

Custom Location Markers and a Plot of Category Counts¶

On the map, the default symbol and color have been changed, and the label size has been reduced. A plot of category counts is shown on top of the user interface.

Custom Symbols, Colors, Marker, and Basemap¶

The location marker has been customized, the location color is specified by a column in the data table, the highlight marker has been customized, and the position of the label has been changed. The basemap has also been changed from the default.

Selection by Query¶

Locations can be selected by entering selection criteria using column names and values from the data table.

Selection by Alternate Queries¶

Multiple data selection dialogs can be active at once, and alternative data selections can be easily and quickly applied using the ‘Apply’ button on the different data selection dialogs. Those selections will be immediately shown on the map and on any plot or other data summary that uses selected data and has the ‘Auto-update’ option selected.

Custom Basemap, Categorized Symbols, and Correlation Matrix¶

Different symbols and colors are used for surface and subsurface samples, on a customized basemap, with a correlation matrix shown in front of the map.

Boxplot With Table of Plot Data¶

When a plot is produced, the data used can be viewed in two forms: the original data (reduced to complete cases and possibly log-transformed), and the data following any additional summarization needed for plotting. This figure shows box plots with the data as summarized.

Time Series Plot¶

A time series plot of data from a single location.

Correlation Matrix¶

A correlation matrix for a subset of variables at selected locations.

Distance Calculation¶

Calculation of the distance between two selected locations. The location marker, selection marker, and basemap have all been customized. The distance calculation dialog is showing only the two locations that have been selected on the map.
