pie chart: i expect dynamic visualise , please click and check my charts and how to visualise dynamically . 我用python动态创建了图表,我必须直接插入到HTML页面中并动态查看图表,但我无法插入到我的HTML页面中。
我可以在HTML页面中将图表显示为图像,而我无法在动态中可视化。
我想知道HTML中关于要从python代码直接插入到我的HTML页面中的绘图和图形的代码,或者任何其他在用户界面中动态可视化绘图和图形的方式。
<h6 class="m-1" >Purchase Stats</h6>
<div>
<img src="{{ pie }}" width="380" height="333">
</div> data=pd.read_csv("sales_data.csv")
df = pd.DataFrame(data)
filtered_data=data[['quantity','states_x']]
filtered_data1=data[['product category']]
#finding the sales by region
sales_by_region = df.groupby('states_x').size()
sales_by_region.head()
filtered_data.states_x.value_counts()[:14].plot(kind='bar')
plt.title('Top 15 Statewise Sales')
plt.xlabel('Region')
plt.ylabel('Total Sales')
plt.tight_layout()
plt.savefig('static/images/bar.png')
### Rendering Plot in Html
##figfile = BytesIO()
#plt.savefig(figfile, format='png')
bar = os.path.join(app.config['UPLOAD_FOLDER'], 'regionwise_sales.png')
return render_template('index.html',pie = pie )

这是我的python代码
import pygal
from flask import Flask,render_template,request,session
from flask.templating import render_template
from pygal.style import Style
import pandas
@app.route('/bar_route')
def bar_route():
try:
bar_chart = pygal.Bar()
bar_chart.title = 'Browser usage evolution (in %)'
bar_chart.x_labels = map(str, range(2002, 2013))
bar_chart.add('Firefox', [None, None, 0, 16.6, 25, 31, 36.4, 45.5, 46.3, 42.8, 37.1])
bar_chart.add('Chrome', [None, None, None, None, None, None, 0, 3.9, 10.8, 23.8, 35.3])
bar_chart.add('IE', [85.8, 84.6, 84.7, 74.5, 66, 58.6, 54.7, 44.8, 36.2, 26.6, 20.1])
bar_chart.add('Others', [14.2, 15.4, 15.3, 8.9, 9, 10.4, 8.9, 5.8, 6.7, 6.8, 7.5])
barchart_data=bar_chart.render_data_uri()
return render_template('barchart.html',barchart_data=barchart_data)
except Exception:
return "error"barchart.html代码如下所示:
{% block content %}
<!-- Don't forget the "|safe"! -->
<div id="chart">
<embed type="image/svg+xml" src= {{ barchart_data|safe }} style="width:50%;height:50%" />
</div>
{% endblock %}那么你的网页将会是
