Starting 2026-08-05, DataVizForge includes automatic axis label rotation that detects when X-axis tick labels would overlap and rotates them to maintain readability. The rotation angle adapts to the number of labels and the chart width — short labels stay horizontal, while dense date ranges or long category names rotate to 45 or 90 degrees as needed.
The feature works across all chart types that use a categorical or time-based X-axis, including bar charts, line charts, and area charts. You can override the auto-rotation in the Axis settings panel and force a fixed angle if your design requires consistent label orientation. The rotation is applied at render time, so exported PNG, SVG, and PDF files all reflect the rotated labels.
This update addresses a common pain point when visualizing time series with daily granularity or categories with long names. Previously, users had to manually rotate labels or abbreviate them to avoid overlap. Now the chart handles it automatically. Feedback: sapsap@qq.com.
