Bar

The Bar Chart is used to compare values across different categories using horizontal or vertical bars. It is useful for visualising differences, trends, rankings, and distributions between groups of data. Bar Charts support single or multiple series and can display aggregated values such as averages, totals, minimums, maximums, and other calculations based on the selected data source.

  2. Data Type — Select the type of data to use:
    • Nodes — Node-based data such as Node Meta, Node Attributes, and Node Analytics (if analytics have been executed).
    • Graph — Graph-level analytics and metrics.
  3. Filters (optional) — Add filters to limit or refine the data:
    • Click Add Filter.
    • Field — Select a field from Node Meta, Node Attributes, or Node Analytics.
    • Operator — Select the filter operator.

    • To delete a series, click the delete icon on its row.
  3. Click Apply.
note

Multiple series can be added to the same chart.

Binning Configuration​

If a numerical field is selected for the X-Axis, you can enable Binning Configuration to group data into value ranges. Binning organises numerical values into intervals for better visualisation and analysis.

  • Binning Method — Select how numerical data is grouped into bins:
    • Fixed Size — Creates bins using a fixed interval size.
    • Auto (Sturges) — Automatically determines the optimal number of bins based on data size.
    • Square Root — Calculates the number of bins using the square root of the total data count.
    • Round — Groups values into rounded intervals.
    • Custom Breaks — Allows you to define custom bin ranges manually.

Depending on the selected method, additional options may appear:

  • Min Range — Minimum value range for the bins.
  • Max Range — Maximum value range for the bins.
  • Bin Size — Size of each bin interval. Applicable for Fixed Size only.
  • Custom Breaks — Custom bin break points as comma-separated values. Applicable for Custom Breaks only.
