# Blank PNG image is shown with toBase64Image() function

If a blank image is shown with the toBase64Image() function, you need to use the following to work on it correctly:

animation: {
duration: 2000,
onComplete: function (animation) {
this.toBase64Image();
}
}

With that, you can also use another fix. Call save64Img(myChart.toBase64Image()) over an additional callback and set it like this:

myLine = {
onAnimationComplete: function () {
save64Img(myChart.toBase64Image());
}
}
