Introduction

The polar bar chart generator draws a bar chart under the polar coordinate system, maps categories to angles, values to radii (radial) or vice versa (tangential), is suitable for the display of periodic and directional data (such as wind direction, month, hour distribution), and can be exported as PNG, JPG, WebP pictures.

Fill in the label, value and color of each item in the data input area (click to add additional items) Select the directional mode (radial/tangential) Optionally fill in the chart title Chart automatic preview Use the download chart to export the image.

Notes

The chart is rendered locally in the browser, and the data is not uploaded to the server; items with a value of 0 or negative will be ignored; in radial mode, the categories are distributed along the circumference, and the columns radiate outward; in tangential mode, the categories are distributed along the radius, and the columns expand along the angle.
