问题描述
我使用ChartJs库构建图形。目前,我的图表有“边距”。我希望将线条图形拉伸到整个宽度和高度,如下所示:
我尝试更改画布的宽度,并且在画布没有全宽的情况下也可以使用,但是我需要使其在全宽上也可以使用:
我的配置:
data: {
datasets: [
{
data: bids,fill: true,pointHiTradius: 10,pointBorderWidth: 0,pointHoverRadius: 4,pointHoverBorderColor: 'white',pointHoverBorderWidth: 2,poinTradius: 0,backgroundColor: 'rgba(58,196,174,0.4)',borderColor: '#3ac4ae',lineTension: 0.7,borderJoinStyle: 'miter',},{
data: asks,backgroundColor: 'rgba(255,107,66,borderColor: '#ff6b42',cubicInterpolationMode: 'default',}
]
},options: {
responsive: true,legend: {
display: false
},scales: {
xAxes: [
{
display: true,type: 'linear',gridLines: {
borderDashOffset: 0,display: true,color: 'rgba(255,255,.1)'
},ticks: {
autoSkip: false,callback: (value,index,values) => {
console.log('valueskol',values)
return value
},beginAtZero: true,padding: 20,}
],yAxes: [
{
display: true,position: 'left',gridLines: {
display: true,.1)',drawBorder: false,offsetGridLines: true,tickMarkLength: 0,drawOnChartArea: true
},ticks: {
min: 0.02,stepSize: 0.1,}
}
如果有人可以帮助我,将不胜感激。
解决方法
将xAxes.ticks.min
设置为最小值X,将.max
设置为最大值,并将yAxes.ticks.padding
设置为0。
这是一个例子。我必须补一些数字,因为您的帖子中缺少数据:
const ctx = document.getElementById('myChart').getContext('2d');
const myChart = new Chart(ctx,{
type: 'line',data: {
datasets: [{
data: [{
x: 1,y: 12
},{
x: 2,y: 11
},{
x: 3,y: 10
},{
x: 4,y: 1
},],fill: true,pointHitRadius: 10,pointBorderWidth: 0,pointHoverRadius: 4,pointHoverBorderColor: 'white',pointHoverBorderWidth: 2,pointRadius: 0,backgroundColor: 'rgba(58,196,174,0.4)',borderColor: '#3ac4ae',lineTension: 0.7,borderJoinStyle: 'miter',},{
data: [{
x: 6,{
x: 7,y: 3
},{
x: 8,y: 5
},{
x: 9,backgroundColor: 'rgba(255,107,66,borderColor: '#ff6b42',cubicInterpolationMode: 'default',}
]
},options: {
responsive: true,legend: {
display: false
},scales: {
xAxes: [{
display: true,type: 'linear',gridLines: {
borderDashOffset: 0,display: true,color: 'rgba(255,255,.1)'
},ticks: {
autoSkip: false,callback: (value,index,values) => {
console.log('valueskol',values)
return value
},beginAtZero: true,padding: 20,min: 1,}],yAxes: [{
display: true,position: 'left',gridLines: {
display: true,.1)',drawBorder: false,offsetGridLines: true,tickMarkLength: 0,drawOnChartArea: true
},ticks: {
padding: 0,}
}]
}
}
});
