Yes, you can enable the 'Normalize to 100%' option to convert all values into relative percentage contributions. ### Can I customize the chart colors? Yes, you can provide a comma-separated list of hex color codes in the 'Area Colors' field to match your branding. ### What is the maximum number of series I can add? There is no strict limit, but for optimal readability, we recommend keeping the number of series manageable to avoid visual clutter. ## Related tools - [Bar Chart Generator](https://elysiatools.com/en/tools/bar-chart-generator): Generate customizable bar charts from data with various styling options - [Bubble Chart Generator](https://elysiatools.com/en/tools/bubble-chart-generator): Generate customizable bubble charts from data with three dimensions (x, y, size) - [Comparison Bar Chart Generator](https://elysiatools.com/en/tools/comparison-bar-chart): Generate back-to-back bar charts for positive and negative value comparison, perfect for contrasting data sets - [Donut Chart Generator](https://elysiatools.com/en/tools/donut-chart-generator): Generate customizable donut charts (ring charts) from data with various styling options, perfect for showing proportions with a central space - [Funnel Chart Generator](https://elysiatools.com/en/tools/funnel-chart-generator): Generate customizable funnel charts from data, perfect for showing conversion rates, sales pipelines, and process flows - [Gantt Chart Generator](https://elysiatools.com/en/tools/gantt-chart-generator): Create professional Gantt charts with task timelines, dependencies, progress tracking, and milestone markers - [Gauge Chart Generator](https://elysiatools.com/en/tools/gauge-chart-generator): Generate customizable gauge charts (speedometer charts) from data, perfect for displaying KPIs, metrics, and performance indicators - [Heatmap Generator](https://elysiatools.com/en/tools/heatmap-generator): Generate customizable heatmaps from data, perfect for visualizing data density, correlations, and patterns ## Samples - [Grafana Advanced Application Samples](https://elysiatools.com/en/samples/grafana-samples): Comprehensive Grafana samples covering advanced dashboard design, alerting configurations, data source integrations, and plugin development - [D3.js Data Visualization Samples](https://elysiatools.com/en/samples/d3js-data-visualization): Comprehensive D3.js data visualization examples including charts, maps, animations, and interactive visualizations - [Terraform Plan JSON Samples](https://elysiatools.com/en/samples/terraform-plan-json-samples): Sample Terraform plan JSON files exported from terraform show -json style payloads for dependency visualization and change review - [QR Code Samples](https://elysiatools.com/en/samples/qrcode-samples): Sample QR code images for testing QR code reading and generation tools
