Custom visual with external library

[vincentd]

Hello,

I try to create my first custom visual on power pi, using highcharts library

I've tried to install it from npm (npm install), try to use typings (typings install) but when I start my visual, "Hightcharts" is undefined (error on my visual.ts).

Has anyone ever used this library to enrich power bi charts?

Thanks

@vincentd,

You could add a let statement as shown below.

let Highcharts = (<any>window).Highcharts;
