[Solved]-plot a bar chart.js time series-Chart.js

I had the exact same issue when displaying a bar chart with time as the X axes.

Inside your xAxes you need to add an additional configuration option:

xAxes: [{
    offset: true
}]

Description from the ChartJS documentation:

If true, extra space is added to the both edges and the axis is scaled to fit into the chart area. This is set to true in the bar chart by default.
