I have a chart showing website calls the last 7 days. There it is:

Here is the initialization:
varwebsitecalls_chart = new Chart(websitecalls_chartel, {
type: 'line',
data: {
labels: ["Sa", "So", "Mo", "Di", "Mi", "Do", "Fr"],
datasets: [{
label: 'Websitecalls',
data: [0, 0, 0, 0, 0, 0, 0],
borderWidth: 2,
borderColor: '#00000',
backgroundColor: '#ffff',
pointStyle: 'circle',
pointRadius: 7,
cubicInterpolationMode: 'monotone',
tension: 0.4,
}]
},
options: {
responsive: true,
plugins: {
legend: {
display: false
},
},
scales: {
x: {
grid: {
display: false,
}
},
y: {
min: 0,
ticks: {
precision: 0,
font: {
family: 'Montserrat',
},
},
grid: {
borderDash: [5, 5],
}
},
}
},
});
Problem:
The Problem is that the chart cuts of the circles when the data is 0 because I set min to 0. I have to set min to 0 because negative websitecalls can not exist. If I do not set it -1 will be displayed. Is there a way to fix this designtechnical issue?
Thanks in advance,
Filip.
No idea why, but defining y.beginAtZero: true instead of y.min: 0 will solve the problem.
Please take a look at your amended and runnable code and see how it works.
new Chart('websitecalls_chartel', {
type: 'line',
data: {
labels: ["Sa", "So", "Mo", "Di", "Mi", "Do", "Fr"],
datasets: [{
label: 'Websitecalls',
data: [0, 0, 0, 0, 0, 0, 0],
borderWidth: 2,
borderColor: '#00000',
backgroundColor: '#ffff',
pointStyle: 'circle',
pointRadius: 7,
cubicInterpolationMode: 'monotone',
tension: 0.4,
}]
},
options: {
responsive: true,
plugins: {
legend: {
display: false
},
},
scales: {
x: {
grid: {
display: false,
}
},
y: {
beginAtZero: true,
ticks: {
precision: 0,
font: {
family: 'Montserrat',
},
},
grid: {
borderDash: [5, 5],
}
},
}
},
});

Chart.js documentation states...
beginAtZero: if true, scale will include 0 if it is not already included.min: user defined minimum number for the scale, overrides minimum value from data.
