Custom Superset charts & plugin development.
When standard Superset runs out of chart types, we build the one you need, waterfall, mekko, whale, advanced tabular reports, and upstream the fixes to the project itself. We are Superset committers, not just users.
Whale Chart - Custom Profitability Visualization
Whale charts are incredibly useful for visualizing cumulative contribution, especially in finance. We built a custom whale chart for a finance-sector client to show how a small percentage of accounts contributed disproportionately to total revenue.
- Helps stakeholders quickly identify key contributors and long-tail segments
- Shows exact cumulative profit contribution per account, ranked visually
- Highlights resource-draining outliers that standard charts miss
- Fully interactive and integrates seamlessly within Superset dashboards
Financial Reporting Format - Advanced Tabular Reports
Reports that combine hierarchical headers, mixed formatting (currency, percentages), subtotals, and multi-level metric groupings require more than standard table visuals. This becomes a significant need for finance, sales, or operations teams relying on structured KPIs for executive reviews.
- Custom chart plugin that replicates 95% of advanced reporting features
- Supports nested headers, custom cell formatting, and row/column subtotals
- Dynamic metric grouping with indentation and conditional styling
- Brings structured reporting into Superset - no need to export to Excel
Mekko Chart - Multi-Dimensional Market View
We added a custom Mekko chart to Superset, enabling users to visualize data with both category share and relative size in a single view. Unlike standard bar charts, the Mekko chart displays variable-width bars, making it ideal for market share, product mix, or segmentation analysis.
- Variable-width bars accurately represent relative market share
- Captures scale, segment performance, and profitability in one compact view
- Built to support multi-dimensional insights within tight dashboard space
- Fully interactive with drill-down and cross-filter support
Fixing Existing Defects & Contributions
When platform defaults fall short, we contribute directly to the source. We actively identify issues, develop fixes, and upstream patches to ensure a robust foundation for enterprise analytics.
- Horizontal waterfall chart support in addition to vertical
- Axis label fixes to word-wrap longer labels instead of hiding them
- Added sorting options and subtotal formatting for waterfall charts
- Cross-filtering now feasible for waterfall charts
- Resolved incorrect legend color mappings post Superset 4.1.2 update
Side-by-Side Filtering - Seamless Comparison
Comparing complex data hierarchies often means toggling filters back and forth, breaking the analytical flow. We solved this with a dual-column filter architecture that enables seamless side-by-side comparison across deep data dives.
- Dual-column layout for comparing two filter states simultaneously
- Nested tree filters with search, expand/collapse, and presets
- Persistent comparison mode keeps both views locked while exploring
- One-click filter presets eliminate repetitive setup for recurring analysis
Executive Health Cards - Operational Clarity
Complex charts are often too noisy for rapid executive feedback. We designed custom operational health cards that translate raw data into color-coded status assessments, enabling instant executive action without deep data exploration.
- Color-coded status summaries (green/amber/red) for instant understanding
- Consolidates scattered KPIs into a single-glance overview grid
- Custom Handlebars extensions with conditional rendering and click-through
- Designed for non-technical users who need clarity, not complexity
Event Visibility - Custom Alert Monitoring
While Superset supports basic alerts via email or Slack, teams often need event visibility directly within the platform. We developed a custom feature that allows users to view triggered alerts, status changes, and event logs directly in the Superset UI.
- Broader team engagement with in-platform alert visibility
- Real-time event feeds for operational monitoring dashboards
- Full incident timeline with searchable logs and timestamps
- Improves transparency and reduces the gap between observation and action
Built by people who ship to Superset itself.
When we hit a bug or a missing feature, we fix it at the source and upstream the patch, horizontal waterfalls, axis-label wrapping, cross-filtering, legend-color fixes after the 4.1.2 release. That means the customizations we build for you sit on a foundation we help maintain, not a fragile fork.
