The Data Explorer node offers a range of options for displaying properties of the input data in an interactive view.
The node supports custom CSS styling. You can simply put CSS rules into a single string and set it as a flow variable 'customCSS' in the node configuration dialog. You will find the list of available classes and their description on our documentation page.
The interactive view consists of three tabs: a Statistics tab, a Nominal tab, and a Data Preview tab. The Statistics and Nominal tabs sum up the information in each column. The user can then decide which columns to include in further analysis.
The Numeric tab shows the main statistical properties of the numerical data, such as minimum, maximum, median (optional), standard deviation, variance, skewness, kurtosis, overall sum, number of zero values, number of missing values, number of not-an-object values, as well as positive and negative infinity values. For each column, the node also calculates a histogram showing the value distribution.
The Nominal tab lists the main properties of the nominal values, such as the number of missing values, unique values, and top n most frequent and infrequent values. In addition, for each data column there is a histogram showing the frequencies with which values occur in this column.
The Data Preview tab shows the data selected for preview.
