3D Bar Charts
3D bar charts render extruded vertical bars anchored to geographic coordinates. Bar height is driven by a numeric attribute in your dataset, making it easy to compare values across locations at a glance.
Creating a 3D bar chart
- Import a GeoJSON or Shapefile layer containing point or polygon geometry.
- Open the Style Editor for that layer.
- Set Layer type to 3D Bar Chart.
- Choose the height attribute from the dataset column list.
Style options
Height attribute
The dataset column whose values determine bar height. Only numeric columns are listed.
Height scale
A multiplier applied to the raw attribute value to convert it to meters. For example, if your attribute is in thousands, set height scale to 1000 so a value of 5 produces a 5 000 m bar.
Bar color
- Fixed color — all bars share a single color
- By attribute — map a categorical or numeric column to a color gradient
Bar width
The horizontal footprint of each bar in meters. Smaller values work better for dense datasets; larger values are easier to read at lower zoom levels.
