我正在尝试制作像这个屏幕截图这样的图表。现在我使用chartjs如下： -<!DOCTYPE html><html><head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=Edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>area > boundaries | Chart.js sample</title> <link rel="stylesheet" type="text/css" href="https://www.chartjs.org/samples/latest/style.css"> <script src="https://www.chartjs.org/dist/2.9.3/Chart.min.js"></script> <script src="https://www.chartjs.org/samples/latest/utils.js"></script> <script src="https://www.chartjs.org/samples/latest/charts/area/analyser.js"></script></head><body> <div class="content"> <div class="wrapper col-2"><canvas id="chart"></canvas></div> </div> <script> var presets = window.chartColors; var utils = Samples.utils; var inputs = { min: 0, max: 100, count: 8, decimals: 2, continuity: 1 }; function generateData(config) { return utils.numbers(Chart.helpers.merge(inputs, config || {})); } function generateLabels(config) { return utils.months(Chart.helpers.merge({ count: inputs.count, section: 3 }, config || {})); } var options = { maintainAspectRatio: false, spanGaps: false, elements: { line: { tension: 0.000001 } }, plugins: { filler: { propagate: false } }, scales: { xAxes: [{ ticks: { autoSkip: false, maxRotation: 0 } }] } };有一个问题，这与屏幕截图不完全一样，我怎样才能使它与屏幕截图中的一样？

您正在正确使用图表，并且正在使用适当的type: line. 您只需设置正确的值即可完全按照图像显示图表。我希望这能给你一个想法
var presets = window.chartColors;
var utils = Samples.utils;
var inputs = {
min: 0,
max: 100,
count: 8,
decimals: 2,
continuity: 1
};
function generateData(config) {
return utils.numbers(Chart.helpers.merge(inputs, config || {}));
}
function generateLabels(config) {
return utils.months(Chart.helpers.merge({
count: inputs.count,
section: 3
}, config || {}));
}
var options = {
maintainAspectRatio: false,
spanGaps: false,
elements: {
line: {
tension: 0.000001
}
},
plugins: {
filler: {
propagate: false
}
},
scales: {
xAxes: [{
ticks: {
autoSkip: false,
maxRotation: 0
}
}]
}
};
[false, 'origin', 'start', 'end'].forEach(function(boundary, index) {
const canvas = document.getElementById('chart-' + index);
if(canvas)
{
utils.srand(8);
var ctx = canvas.getContext('2d');
new Chart(ctx, {
type: 'line',
data: {
labels: generateLabels(),
datasets: [{
backgroundColor: utils.transparentize(presets.red),
borderColor: presets.red,
//data: generateData(),
data: [0, 0, 40, 0,0, 50, 0, 0, 0],
label: 'Dataset',
fill: boundary
}]
},
options: Chart.helpers.merge(options, {
title: {
text: 'fill: ' + boundary,
display: true,
}
})
});
}
});
