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. ## Related tools - [CSV Histogram, Scatter and Box Plot Chart Studio](https://elysiatools.com/en/tools/csv-histogram-scatter-box-plot-chart-studio): Upload or paste a CSV and chart it instantly: histograms with Sturges / Freedman-Diaconis / Scott binning, scatter plots with Pearson r and a least-squares fit, and Tukey box plots — every chart downloadable as PNG and SVG. - [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 - [Line Chart Generator](https://elysiatools.com/en/tools/line-chart-generator): Generate customizable multi-line charts from data with various styling options - [Pictograph Generator](https://elysiatools.com/en/tools/pictograph-generator): Create pictographs using icons/symbols to represent quantities with customizable icons, colors, and layouts - [Progress Bar Generator](https://elysiatools.com/en/tools/progress-bar-generator): Generate customizable progress bars from data, perfect for showing completion status, rankings, or comparative values - [Radar Chart Generator](https://elysiatools.com/en/tools/radar-chart-generator): Generate customizable radar charts (spider charts) from data, perfect for multi-dimensional comparison and analysis - [Range Chart Generator](https://elysiatools.com/en/tools/range-chart-generator): Create range charts to visualize min-max value ranges with median markers and outlier detection ## Samples - [Chart.js Chart Library Samples](https://elysiatools.com/en/samples/chartjs-library): Comprehensive Chart.js examples including various chart types, customization options, animations, and responsive designs - [Helm Chart Samples](https://elysiatools.com/en/samples/helm-chart): Complete Helm chart examples with templates, values, dependencies, and package management configurations - [Copyright-Free MP3 Audio Samples](https://elysiatools.com/en/samples/mp3-samples): Collection of royalty-free audio samples for testing and development purposes including nature sounds, meditation music, and ambient audio - [Web Image Processing Python Samples](https://elysiatools.com/en/samples/web-image-processing-python): Web Python image processing examples using PIL/Pillow including reading, saving, resizing, and format conversion ## Related content - [Chart and Diagram Generators](https://elysiatools.com/en/hubs/chart-diagram-generators): Choose a chart or diagram that makes comparisons, distributions, hierarchies, relationships, and schedules understandable.
