i use for my project this chart pygal
from datetime import datetime, timedelta
datey = pygal.DateY(x_label_rotation=20)
datey.add("Visits", [
(datetime(2013, 1, 2), 300),
(datetime(2013, 1, 12), 412),
(datetime(2013, 2, 2), 823),
(datetime(2013, 2, 22), 672)])
datey.render()
but the problem is when i want to use datetime from my base i have this
error TypeError: can't compare datetime.datetime to float i used this code
hum = []
temp = []
for u in users:
hum.append((u.temperature ))
temp.append((u.timew))@app.route('/something.svg')
def graph_something():
datey = pygal.DateY(x_label_rotation=20, show_dots=False)
datey.add("Visits",
(temp, hum))
return datey.render()
