Startup Funding in Angular

Using ApexCharts with Angular

This Startup Funding example wires ApexCharts into Angular through the ng-apexcharts component.

Install it with npm install ng-apexcharts apexcharts, then mount the chart with <apx-chart [series]="series" [chart]="chart"></apx-chart>.

Angular charts guide

This demo uses imperative chart updates. The generated code is a faithful Angular translation: open it in CodeSandbox to run and tweak.
