Charts js showing only when positives data

I have an issue with charts js bar.
Here's the options :
trendChart = new Chart(ctx, {
type: 'bar',
data: {
labels: dynamicLabels,
datasets: [{
label: label1,
data: displayedDatas1,
borderColor: colors,
backgroundColor: colors,
fill: false,
borderWidth: 2
}]
},
options: {
showDatapoints: true,
tooltips: {
callbacks: {
label: function (tooltipItem, data) {
return data['datasets'][0]['data'][tooltipItem['index']] + ' %';
}
}
},
maintainAspectRatio: false,
legend: {
display: false
},
emptyOverlay: { // enabled by default
fillStyle: 'rgba(105,105,105,0.4)', // Change the color of the overlay to grey with a 40% alpha
fontColor: 'rgba(47,47,47,1.0)', // Change the text color to white
fontStroke: 'rgba(47,47,47,0)', // Change the text color to white
fontSize: $(window).width() > 1007 ? 25 : 15,
message: "Veuillez sélectionner vos activités et services, et choisissez une période",
fontStrokeWidth: 0 // Hide the stroke around the text
}
}
});
And how I update the data :
trendChart.data.datasets[0] = {
label: label1,
data: displayedDatas1,
borderColor: colors,
backgroundColor: colors,
fill: false,
borderWidth: 2
};
trendChart.data.labels = dynamicLabels;
trendChart.update();
The issue is when I have only negative data, the bars are not shown but when there is at least one positive data they magically appear.
I already tried: scaleBeginAtZero and ticks in the options.
Thanks

Try adding scaleBeginAtZero: false to your options object.
scaleBeginAtZero: false

Found it!
The issue was the plugin: chartjs-plugin-empty-overlay.js.
When disabling it the negative values are showing.
Should have read the doc, it was only tested for the line chart.
