Hi
Try separate function for form & chart and in the view/form.html you can
use function {{ =LOAD('chart', ...) }}
or
You can embedded python chart code into form.html for example:
{{
import pygal
from pygal.style import DefaultStyle
from pygal import Config
config = Config()
config.human_readable = True
line_chart = pygal.Line(title = 'COMPANY',
x_labels = map(lambda d: d.strftime('%Y-%m-%d'), [each_day[0] for
each_day in daily_sales_each_day]),
x_label_rotation = 20,
dots_size = 5,
title_font_size = 20,
label_font_size = 10,
legend_font_size = 10,
value_font_size = 10,
legend_at_bottom = True,
tooltip_font_size = 14,
value_formatter = lambda ml:
'{:,.2f}'.format(ml),
style = DefaultStyle)
line_chart.add('Sales Order', [each_day[1][0][1] or 0 for each_day in
daily_sales_each_day])
=TAG(line_chart.render())
}}
hope it help.
