  • •Customize the chart appearance by selecting a color scheme, adjusting the chart height, and toggling display options like grid lines or legends.
  • •Choose your preferred value format, such as currency or percentage, to ensure the data is presented clearly.
  • •Generate the interactive chart to view, hover for tooltips, or export for your project.

Examples

1. Quarterly Product Sales Analysis

Sales Analyst
Background
A sales analyst needs to present how different product lines contributed to total revenue over four quarters.
Problem
Standard tables make it difficult to see the total growth while simultaneously identifying which products are driving that growth.
How to Use
Input the quarterly sales data for each product, set the value format to 'Currency ($)', and enable tooltips for detailed viewing.
Example Config
[{"category": "Q1", "series": "Product A", "value": 100}, {"category": "Q1", "series": "Product B", "value": 150}, {"category": "Q2", "series": "Product A", "value": 120}, {"category": "Q2", "series": "Product B", "value": 180}]
Outcome
A clear, interactive stacked bar chart showing total quarterly revenue with distinct color-coded segments for each product.
