ng2-charts: Chart not showing using Angular2 RC1 in CLI project
I’m having trouble integrating ng2-charts into a CLI project. After spending hours trying to use charts in a CLI project, I finally got it integrated and it builds/runs without errors, but the graph doesn’t show up. I can see that the directive is getting rendered (there’s a <canvas> element within the base-chart element), but it’s all empty.
I took the following steps:
-
Created a new project (named dependencies) using
ng new dependencies -
Followed the installation instructions for ng2-charts, i.e., executed
npm install ng2-charts --savenpm install chart.js --saveand added a script reference to the index.html (<script src="vendor/chart.js/dist/Chart.min.js"></script>) -
Adjusted the angular-cli-build.js to copy the npm files into the dist directory:
vendorNpmFiles: [ … ‘chart.js/dist/Chart.min.js’, ‘ng2-charts/*/.js’ ]
-
Adjusted the system.config.js in order to map the name ‘ng2-charts’ to the respective vendor directory and the package name ng2-charts to it’s main file.
const map: any = { ‘ng2-charts’: ‘vendor/ng2-charts’ }; /** User packages configuration. */ const packages: any = { ‘ng2-charts’: { main: ‘bundles/ng2-charts.min.js’
}
}; -
Copied the ts code/html from the line chart example (http://valor-software.com/ng2-charts/)
Anyone knows the issue or has a project using Angular2 CLI with ng2-charts integrated? I uploaded the code to https://github.com/thorstenschaefer/dependencies. All changes from the newly created CLI project can be seen here: https://github.com/thorstenschaefer/dependencies/commit/8169b429d37b72bb9e8718b76d27c258602d1c07

Hello thorstenschaefer, I’m facing the exact same issue and I can’t figure out why. 😦
It works… strangely.
I am using the charts in an Ionic 2 project (based on Angular 2). To make them work I had to insert the following in app.ts:
It’s supposedly not recommended referencing files this way, but it’s what made it work in the end (after many tries).
@Warkdev Thanks a lot man. Setting the CSS worked for me too. Just the style attribute { display:block } is enough in my case.
After searching a bit more, it looks to me that this is similar to https://github.com/valor-software/ng2-charts/issues/53 which was marked as fixed. Shouldn’t the base-chart component have the display style set to blocked by default?
I use an Ionic 2.
I have tried:
No success…
.chart {display: block; width: 100%;} It works for me…I spent 5 hrs to resolve this…thanks…
Agreed, I will do
