Support for themes? about angular-highcharts HOT 13 OPEN

UPDATE:
The procedure mention in #59 (comment) is working in Angular 5. Tried and tested!

from angular-highcharts.

@tavuntu yes, the following should work.

import { Highcharts } from 'angular-highcharts';

// Apply the theme
Highcharts.setOptions(Highcharts.theme);

from angular-highcharts.

The object Highcharts is undefined when importing it, so it throws an error when trying to use .theme or .setOptions(). I've added the ChartModule un app.moduel.ts, maybe I'm missing something else?

EDIT: this results in an undefined object as well... weird:
import { Highcharts } from 'highcharts';

from angular-highcharts.

To resolve this issue i need more code to dig into this. Can you setup a minimal repo or Plunkr?

from angular-highcharts.

here you go, I'm using npm 5.4.0 and the latest version of angular-highcharts
https://github.com/tavuntu/general-stuff

from angular-highcharts.

Was this issue resolved? Is there any workaround?

from angular-highcharts.

@SayakMukhopadhyay I haven't tested this since then (I switched to Chart.js), are seeing the issue?

from angular-highcharts.

Yeah, I am. I am planning on the only workaround of loading the theme js in the header for now. Using setOptions is more flexible though.

from angular-highcharts.

Highcharts.setOptions(Highcharts.theme); seems to affect the new charts after it.

What would the easiest way to refresh the charts so that the new theme is applied immediately to existing charts?

from angular-highcharts.

If you don't mind looking through source code, I have implemented a dynamic theme switcher in https://github.com/SayakMukhopadhyay/elitebgs . This is the service file . The theme switch is triggered in this component and the chart is rendered in this component

from angular-highcharts.

Interesting, so you are basically recreating the chart when switching themes right?

this.themeService.theme$.subscribe(theme => {
            this.chart = new Chart(this.options);
        });

By doing

this.linkRef.onload = () => this.themeService.themeLoaded();

and

this.linkRef.href = this.themeService.getTheme().href;

You are loading the style sheet related to the theme dynamically and also triggering the theme change, right?

from angular-highcharts.

Yup. Recreating the chart object is the only way to change the theme as far as what I have found.

from angular-highcharts.

I was able to get it working like this:

this.chart = new Chart({...});
this.chart.theme = {...};
Highcharts.setOptions(this.chart.theme);
