I was using echarts v5.4.3 with ngx-echarts 15.0.3 and angular 15, but when I updated echarts to v5.5.0 I notice that the theme is not working. I have an application as a library where I am using the echarts and ngx-echarts packages to create some graphics and there it is working correctly, I have problems in the application when I install this package. Echarts is a peerDependency of this package as well as ngx-echarts. In the library I am only importing the theme in the module by this way: import 'echarts/theme/macarons.js'; import * as echarts from 'echarts'; import { NgxEchartsModule } from 'ngx-echarts'; @NgModule({ imports: [ NgxEchartsModule.forRoot({ echarts }) ], And I am using this way to create the graphics: <div echarts [options]="echartsOption" theme="macarons"></div> So the graphics must displayed correctly in the application with the macaron theme as well as in the library. Because if I run the library package it displays correctly, it is in the application where you can see that it does not pick up the theme styles. Should I add something in the angular.json or in some other file? For example in the scripts section of angular.json like: "scripts": [ "node_modules/echarts/dist/echarts.js", "node_modules/echarts/theme/macarons.js", ], Although with the previous version I didn't need to add any of this.
