Define your own chart by combining primitives—line segments, scatter points, area fills—using our advanced editor.
Choose from pre-designed palettes (material, pastel, vibrant) or define custom hex/RGB values for each series.
Select font families and sizes for titles, axis labels, and tick marks. Apply bold/italic and text rotation for readability.
Position legend top, bottom, left, or right. Add text boxes, arrows, and shapes to emphasize data points directly on the chart.
Switch between linear, logarithmic, or custom scales. Toggle major/minor grid lines, adjust line styles and opacity.
Enable hover tooltips displaying formatted values, clickable series toggles, and zoom/pan controls for exploration.
Automatically adapt chart theme based on user preference or force a specific mode for embedding consistency.
Automate chart creation by sending data and configuration JSON to our REST API:
POST /api/charts
Content-Type: application/json

"data": {
"labels": ["Jan","Feb","Mar"],
"datasets": [
