This is a simple Angular 10 demonstration of the QuickPlot directive that is designed to provide rapid comparison of multiple functions and/or data points across a common range. It is quick, simple, and without frills such as axes, grids, and other graph annotations.
The Angular 10 demo provided with the code distributions provides examples of how to add plot layers and plot data points, lines, line segments, and arbitrary functions that are defined across the domain of the plottable area.
NOTE: Understand that an Angular Directive life cycle runs behind that of its containing component. This is why plot layers are defined in an on-init handler, but the actual plotting is deferred to after view init.

The following methods are available. 'Add' methods add the specified data to anything already plotted in the layer. Call the clearLayer method to clear any prior graphics in advance. The graphFunction method clears its layer before computing and graphing the specified function.
addLayer(layerName: string): PIXI.Graphics | null;
clearLayer(layerName: string): void;
addLine(layerName: string, lineWidth: number, color: number | string, x1: number, y1: number, x2: number, y2: number): void
addSegments(layerName: string, lineWidth: number, color: number | string, points: Array<{x: number, y: number}>): void
addPoint(layerName: string, x: number, y: number, r: number, c: number | string): void
graphFunction(layerName: string, lineWidth: number, color: number | string, f: GraphFunction): void
Run ng serve
for a dev server. Navigate to http://localhost:4200/
. The app will automatically reload if you change any of the source files.
Run ng generate component component-name
to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module
.
Run ng build
to build the project. The build artifacts will be stored in the dist/
directory. Use the --prod
flag for a production build.
