This article explains how to reduce or prevent overlapping labels by using:

Steps to Prevent Axis Label Overlap
Step 1: Open the dashboard and select the Column Chart widget
Open the required dashboard in Bold BI Dashboard Designer, then select the Column Chart widget.
Step 2: Open the Properties panel and expand Axis settings
In the Properties panel, expand the Axis settings section.
Step 3: Rotate the category axis labels
Use Category axis label rotation to angle the labels and reduce overlap.
Common values include:
45°90°
Choose the angle that makes the category names easier to read.
Step 4: Disable Auto Interval if you want manual control
By default, Auto Interval is enabled. Bold BI uses it to automatically determine the spacing of category axis labels.
If you want to control label density manually, disable Auto Interval.
Step 5: Set a custom Interval value
After disabling Auto Interval, set the Interval value to show fewer labels on the axis.
For example:
2shows every second label3shows every third label
This is useful when the chart contains many categories.
Step 6: Choose a Label overflow mode
Use Label overflow mode to control how overlapping category labels are displayed.
Available options include:
- Trim – shortens the visible text
- Hide – prevents overlapping labels from being displayed
Choose the option that best fits your dashboard layout.
Step 7: Enable Trim Axis Labels and set Label Maximum Width
If you want long labels to be shortened instead of fully shown, enable Trim Axis Labels.
Then set Label Maximum Width to control how much label text is visible before trimming occurs.
Enable Trim Axis Labels
Set Label Maximum Width
Step 8: Save and preview the dashboard
Save the dashboard and preview it to confirm that the category axis labels are now easier to read.
Expected Result
After completing these steps:
- Category axis labels are easier to read
- Label overlap is reduced or eliminated
- The column chart has a cleaner appearance
