I am trying to display a multi dimensional bar chart using mpld3 and django framework.
when I run the following code, it produces error
Object of type 'ndarray' is not JSON serializable
at fig_to_html() function line
here I attached my working copy:
view.py
def home(request):
get_barchart = barchart()
return render(request,"home.html",{
"barchart":get_barchart
}
)
def barchart():
fig = plt.figure()
plt.scatter([1, 10], [5, 9])
html_graph = mpld3.fig_to_html(fig)
return html_graph
html template:
<html>
<head>
<title>Chart Example</title>
</head>
<body>
<h3>Chart Example</h3>
<div>
{{ barchart|safe }}
</div>
</body>
</html>
