Currently, when creating a chart with hierarchical or multi-level category data, ONLYOFFICE does not visually group the categories on the axis. Having multi-level labels makes it much easier to read nested data structures.
To illustrate, consider this sample dataset containing two levels of categories (Level 1: DD/EE, Level 2: A/B):
DD EE
A B A B
1 4 5 8
2 3 4 7
3 2 3 4
In Excel, creating a column chart from this data automatically generates a clean X-axis where “A” and “B” are shown individually, neatly grouped under overarching “DD” and “EE” labels using visual dividers.
