  7. Tools icon: Used to open the Data Explorer
  8. Resize icon: Maximize or Restore the visualization size to fill the browser window size

To show the menus, click on any white space within the graph. This brings up different types of content depending on the type of graph. There are various options, such as menus for bar graphs, scatter plots, etc.

# Configurator

Double-clicking on any white space in the graph brings up the configurator, a widget used for searching for the parameter needed. It is designed to show the various available parameters as the user types them in, which is followed by selecting and changing the value of any specific parameter.

# Data Explorer

This option is for the configuration of the visualization. It works by a drag-and-drop function, through which the user can access many customizations.

The Data Explorer has three sections:

  • The top section contains clickable icons to change various parameters and target icons that receive input from the other two sections using drag and drop
  • The middle section comprises variables and their metadata
  • The bottom section contains samples and their metadata

# Data Filters

Data filters can be automatically configured, depending on the type of metadata included in the visualization. This can be either numeric (continuous) or discrete (categorical).

The filter might appear as a checkbox, or a searchable drop-down menu with multiple sections, depending on the number of categories available. With the numerical filters, the user can toggle between both the log and the normal space.

A crossed icon on top is designed for resetting all the filters when or if necessary.

# Data Table

Use this widget to view both the data as well as the metadata included in the visualization.
