  • •Creating clean, readable charts for reports, presentations, or data dashboards.

How It Works

  • •Select your preferred curve type, such as linear, smooth, or step, to define the line style.
  • •Adjust visual settings like fill opacity, colors, and axis labels to match your branding.
  • •Generate the chart and preview the result with optional grid lines, data points, and legends.

Examples

1. Monthly Revenue Trend

Financial Analyst
Background
Need to present a clear view of revenue growth over the first six months of the year.
Problem
Standard line charts don't emphasize the volume of revenue as effectively as filled area charts.
How to Use
Input the monthly revenue data in JSON format and select 'Smooth' curve type for a professional look.
Example Config
{"curveType": "smooth", "fillOpacity": 0.4, "chartTitle": "H1 Revenue Growth"}
Outcome
A polished, smooth-curved area chart that highlights the cumulative revenue growth clearly.

2. Multi-Channel Traffic Comparison

Marketing Manager
Background
Comparing traffic from Organic, Social, and Paid channels over a week.
Problem
Overlapping lines make it difficult to see the contribution of each channel individually.
How to Use
Input the daily traffic data for all three channels and enable the 'Stacked Areas' option.
Example Config
{"stacked": true, "showLegend": true, "xAxisLabel": "Day", "yAxisLabel": "Visitors"}
Outcome
A stacked area chart that shows both the total traffic and the specific contribution of each marketing channel.

FAQ

What data formats are supported?

You can input data as a single-line JSON array, a multi-line JSON object, or simple text pairs separated by colons.

Can I compare multiple data series?

Yes, by using the multi-line JSON format, you can define multiple series to be displayed on the same chart.

What is the difference between linear and smooth curves?

Linear curves use straight lines between data points, while smooth curves apply a spline interpolation for a curved, aesthetic look.

Can I stack the areas?

Yes, enable the 'Stacked Areas' option to display series on top of each other instead of overlapping.

How do I change the chart colors?

Use the 'Area Colors' field to input comma-separated hex codes (e.g., #3b82f6,#ef4444) to customize the appearance of each series.
