ChartJS: chart not show all data

问题

For some reason, this chart not show the last two data from the array.

var data = {
    labels: ["Brasil", "Argentina", "Chile", "Paraguai", "Peru", "Bolívia", "México"],
    datasets: [{
        data: [ 9.19, 7.77, 6.80, 6.23, 6.00, 4.00, 4.00 ],
        backgroundColor: backgroundColor
    }],
};

Anyone known why is this happens?

回答1:

you need to set Y-Axis to start with 0, by default it start with the minimum value present in the data set which is 4 in your case. Due to this last 2 columns with value 4 are not visible.

 yAxes: [{
            ticks: {
                beginAtZero: true
            }
        }]

The y-scale on your graph has a minimum of 4. The value of your last 2 points is 4, so they are not shown. Set the min to 0, or at least less than 4 and they will show.
