我正在使用 ChartJS,但我不知道如何摆脱工具提示中的白框。什么设置/选项将设置删除边框/白色轮廓或至少让我设置颜色?
谢谢!
data_sets.push({
data: date_list["data_counts"],
label: date_list["name"],
fill: true,
backgroundColor: transparentizeColor,
borderColor: newColor,
pointBackgroundColor: newColor,
pointBorderColor: newColor,
})
my_chart = new Chart(ctx, {
type: 'line',
data: {
labels: data["date_labels"],
datasets: data_sets
},
options: {
tooltips: {
intersect: false,
},
elements: {
point: {
radius: 0
}
},
legend: {
display: false
},
scales: {
yAxes: [{
ticks: {
precision: 0,
suggestedMax: 3,
beginAtZero: true
}
}],
xAxes: [{
gridLines: {
display: false
}
}]
}
}
}, );
