【问题描述】:
我正在尝试设置 Chart.js 以在我的项目中使用。 这是example,我正在尝试复制,我得到this 我使用的是 PyCharm,所以很容易下载所有库,我在 Installed aps 中添加了 chart.js
我的 test.html:
{% load staticfiles %}
<html>
<head>
<title>django-chartjs line chart demo</title>
<!--[if lte IE 8]>
<script src="{% static 'js/excanvas.js' %}"></script>
<![endif]-->
</head>
<body>
<h1>Some Line Charts loaded in Ajax!</h1>
<canvas id="myChart" width="500" height="400"></canvas>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.0.min.js"></script>
<script type="text/javascript" src="{% static 'js/Chart.min.js' %}"></script>
<script type="text/javascript">
$.get('{% url "line_chart_json" %}', function(data) {
var ctx = $("#myChart").get(0).getContext("2d");
new Chart(ctx, {
type: 'line', data: data
});
});
</script>
</body>
</html>
我的看法:
class LineChartJSONView(BaseLineChartView):
def get_labels(self):
"""Return 7 labels for the x-axis."""
return ["January", "February", "March", "April", "May", "June", "July"]
def get_providers(self):
"""Return names of datasets."""
return ["Central", "Eastside", "Westside"]
def get_data(self):
"""Return 3 datasets to plot."""
return [[75, 44, 92, 11, 44, 95, 35],
[41, 92, 18, 3, 73, 87, 92],
[87, 21, 94, 3, 90, 13, 65]]
line_chart = TemplateView.as_view(template_name='main/mark/test.html')
line_chart_json = LineChartJSONView.as_view()
