Outside of the following chart types: ### Chart Types * Horizontal & Vertical Bar Charts (Standard, Grouped, Stacked, Normalized) * Line * Area (Standard, Stacked, Normalized) * Pie (Explodable, Grid, Custom legends) * Donut * Gauge * Linear Gauge * Force Directed Graph (deprecated - please use [ngx-graph](https://github.com/swimlane/ngx-graph) instead) * Heatmap * Treemap * Number Cards * Bubble/Scatter * Vertical Box Chart ### Customization * Autoscaling * Timeline Filtering * Line Interpolation * Configurable Axis Labels * Legends (Labels & Gradient) * Advanced Label Positioning * Real-time data support * Advanced Tooltips * Responsive Layout * Data point Event Handlers * Works with ngUpgrade * Enabling/Disabling animations If you have an idea for a new feature, create a Github issue or even better a PR ;). Make sure to include the use case, an example image of the chart (if applicable) and data formats. ## Alternatives Chart frameworks are a dime a dozen nowadays. Not many of them existed a few years ago when we started this project internally and many of them still don't really work well with Angular. Here's a recent list we compiled during our effort to open-source this: * [ng2-nvd3](https://github.com/krispo/ng2-nvd3) - Open-source wrapper for nvd3 using Angular2 Components * [ng2-charts](http://valor-software.com/ng2-charts/) - Open-source Angular2 wrapper directives for Chart.js * [angular2-highcharts](https://www.npmjs.com/package/angular2-highcharts) - Open-source Angular2 wrapper for HighCharts * [recharts](http://recharts.org/) - Open-source composable charting library built on React components * [Vega](http://vega.github.io/) - Open-source Canvas/SVG viz framework * [C3](http://c3js.org/) - Open-source D3-based reusable chart library * [Plotly](https://plot.ly/) - Commercial business intelligence and data science. * [Highcharts](http://www.highcharts.com/) - Commercial chart framework * [eCharts](http://echarts.baidu.com/demo.htm) - Open-source JavaScript chart framework * [dc.js](http://dc-js.github.io/dc.js) - Open-source JavaScript charting library --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://swimlane.gitbook.io/ngx-charts/features.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
