A stacked bar chart with negative values extends bars in both directions from the baseline, creating a butterfly-style layout. This approach is perfect for comparing two opposing groups within the same categories.
This sample shows cosmetic product revenue split by gender: female purchases extend right and male purchases extend left using negative values. Custom axis label formatting displays all values as positive, and HTML-enabled tooltips show dollar amounts for each gender. An interactive legend lets you toggle each series on and off.
