VisualizaçõesChartJS: single bar of bar chart. I want a border around entire bar, including the max Y-value
I want to create a single bar using a bar chart. The setup is that the user can select different choices (representing the colors). In this example (codesandbox link below) I have a bar that has a max value of 90.000. The three chosen values are 20.000, 30.000 and 15.000, totaling 65.000.
Now, my goal is to have a border around this entire bar, not just the colors. In the image below this is represented with the red border. Currently I do this by putting a container element around my canvas element, but I would like to do this in the canvas itself, without using a container element. Someone has an idea on how to do this?

You need to define different dataset properties such as borderSkipped, borderRadius, borderWidth to achieve what you're looking for.
Don't know why but I also had to define the data of the dataset at the bottom as a floating bar in order to see the rounded border.
data: [[0, 20000]]
Please take a look at the runnable code below and see how it could work.
new Chart('chart', {
type: 'bar',
data: {
labels: [''],
datasets: [{
label: "currentAmount",
data: [[0, 20000]],
backgroundColor: "#bbb",
borderColor: "#f00",
borderWidth: 2,
borderSkipped: 'top',
borderRadius: 30,
barPercentage: 0.5
},
{
label: "amount 1",
data: [30000],
backgroundColor: "orange",
borderColor: "#f00",
borderWidth: { left: 2, right: 2 },
barPercentage: 0.5
},
{
label: "amount 2",
data: [15000],
backgroundColor: "green",
borderColor: "#f00",
borderWidth: { left: 2, right: 2 },
barPercentage: 0.5
},
{
label: "remaining",
data: [25000],
backgroundColor: "#fff",
borderColor: "#f00",
borderWidth: 2,
borderSkipped: 'bottom',
borderRadius: 30,
barPercentage: 0.5
},
]
},
options: {
plugins: {
legend: {
display: false
},
tooltip: {
displayColors: false
}
},
scales: {
y: {
display: false,
stacked: true,
beginsAtZero: true
},
x: {
display: false,
stacked: true
}
}
}
});canvas {
max-width: 200px;
