	if 'x_is_date' not in kw_extra:
	kw_extra['x_is_date'] = False
	if 'x_axis_format' not in kw_extra:
	kw_extra['x_axis_format'] = "%d %b %Y"
	if 'color_category' not in kw_extra:
	kw_extra['color_category'] = "category20"
	if 'tag_script_js' not in kw_extra:
	kw_extra['tag_script_js'] = True
	if 'chart_attr' not in kw_extra:
	kw_extra['chart_attr'] = {}
	# set the container name

The above syntax can be changed to the following.

kw_extra['x_is_date'] = kw_extra.get('x_is_date', False)
kw_extra['x_axis_format'] = kw_extra.get('x_axis_format', "%d %b %Y")
kw_extra['color_category'] = kw_extra.get('color_category', "category20")
kw_extra['tag_script_js'] = kw_extra.get('tag_script_js', True)
kw_extra['chart_attr'] = kw_extra.get('chart_attr', {})
