如何在图表的传说中增加字体大小。
我正在尝试在我使用Chart.js的图中增加标签的字体大小。 附带有屏幕截图: 我想增加“标签1,2,3”的字体尺寸。
在我现在正在使用的JavaScript配置下方:
var data = {
labels: x_axis_labels,
datasets: [
{
label: 'Label 1',
data: data_1,
borderColor: 'rgb(46,138,207)',
backgroundColor: 'rgb(46,138,207)',
yAxisID: 'y',
},
{
label: 'Label 2',
data: data_2,
borderColor: 'rgb(214,224,52)',
backgroundColor: 'rgb(214,224,52)',
yAxisID: 'y1',
},
{
data: data_3,
label:'Label 3',
borderColor: 'rgb(244,67,54)',
backgroundColor: 'rgb(244,67,54)',
yAxisID: 'y1',
pointStyle:'dash',
borderDash: [20, 30],
pointBackgroundColor: "transparent",
},
]
};
const config = {
type: 'line',
data: data,
options: {
responsive: true,
interaction: {
mode: 'index',
intersect: false,
},
stacked: false,
plugins: {
title: {
display: true,
}
},
scales: {
x:{
title:{
display: true,
text: 'X axis name',
font: {size:30},
},
ticks: {
font: {
size: 20,
}
}
},
y: {
title:{
display: true,
text: 'First y axis name',
font: {size:30}
},
type: 'linear',
display: true,
position: 'left',
ticks: {
font: {
size: 24,
}
}
},
y1: {
title:{
display: true,
text: 'Second Y axis name',
font: {size:30}
},
type: 'linear',
display: true,
position: 'right',
ticks:{
font:{
size:24,
}
},
// grid line settings
grid: {
drawOnChartArea: false,
},
},
},
},
};
我尝试了 font documnation and logend documentation 但是我什么都没有。 有人有经验吗? 提前致谢
I am trying to increase labels' font size in the legend of a plot that I have done with chart.js.
Attached there is a screenshot:
I want to increase the font size of "Label 1,2,3".
Below the javascript configuration that I am using right now:
var data = {
labels: x_axis_labels,
datasets: [
{
label: 'Label 1',
data: data_1,
borderColor: 'rgb(46,138,207)',
backgroundColor: 'rgb(46,138,207)',
yAxisID: 'y',
},
{
label: 'Label 2',
data: data_2,
borderColor: 'rgb(214,224,52)',
backgroundColor: 'rgb(214,224,52)',
yAxisID: 'y1',
},
{
data: data_3,
label:'Label 3',
borderColor: 'rgb(244,67,54)',
backgroundColor: 'rgb(244,67,54)',
yAxisID: 'y1',
pointStyle:'dash',
borderDash: [20, 30],
pointBackgroundColor: "transparent",
},
]
};
const config = {
type: 'line',
data: data,
options: {
responsive: true,
interaction: {
mode: 'index',
intersect: false,
},
stacked: false,
plugins: {
title: {
display: true,
}
},
scales: {
x:{
title:{
display: true,
text: 'X axis name',
font: {size:30},
},
ticks: {
font: {
size: 20,
}
}
},
y: {
title:{
display: true,
text: 'First y axis name',
font: {size:30}
},
type: 'linear',
display: true,
position: 'left',
ticks: {
font: {
size: 24,
}
}
},
y1: {
title:{
display: true,
text: 'Second Y axis name',
font: {size:30}
},
type: 'linear',
display: true,
position: 'right',
ticks:{
font:{
size:24,
}
},
// grid line settings
grid: {
drawOnChartArea: false,
},
},
},
},
};
I have tried Font Documnetation and Legend Documentation but I got nothing.
Someone had experience in this?
Thanks in advance
