Pyecharts全局配置项共有23小项，今天通过Pyecharts创建树图、图表和实例，具体了解“TitleOpts：标题配置项”的使用方法。

1、tree来实现：

实现代码：

from pyecharts import options as opts

from pyecharts.charts import Tree

data = [

{

"name": "TitleOpts:标题配置项",

"children":[

{

"name": "标题",

"children":[

{"name": "名称",

'children':[{"name": "title= '标题名称',"},

{"name": "title= '标题可通过\\n换行'"},

],

},

{"name": "链接",

'children':[{"name": "title_link= 'http://www.baidu.com'"},

],},

{"name": "链接跳转方式",

'children':[{"name": "title_targe=blank',"},

{"name": "title_targe=self"},

],

},

],

},

{

"name": "副标题",

"children":[

{"name": "名称",

'children':[{"name": "title= '副标题名称',"},

{"name": "title= '副标题可通过\\n换行'"},

],

},

{"name": "链接",

'children':[{"name": "title_link= 'http://www.baidu.com'"},

],},

{"name": "链接跳转方式",

'children':[{"name": "title_targe='blank',"},

{"name": "title_targe='self'"},

],

},

],

},

{

"name": "位置",

"children":[

{"name": "左","children":[{"name": "pos_left=20"},],},

{"name": "右","children":[{"name": "pos_right=20"},],},

{"name": "上","children":[{"name": "pos_top=20"},],},

{"name": "下","children":[{"name": "pos_bottom=20"},],},

],

},

{

"name": "间距",

"children":[

{"name": "内边距","children":[{"name": "padding= 5"},{"name": "padding= [50,50,50,50],"}],},

{"name": "主副间距","children":[{"name": "item_gap=10"},],},

],

},

{

"name": "字体样式",

"children":[

{"name": "标题字体样式","children":[{"name": "title_textstyle_opts= opts.TextStyleOpts(color=\"red\"),"},],},

{"name": "副标题字体样式","children":[{"name": "subtitle_textstyle_opts= opts.TextStyleOpts(color=\"blue\"),"},],},

],

},

],

}

]

c = (

Tree(init_opts=opts.InitOpts(width="1400px", height="800px", ))

.add("", data,is_roam= False,is_expand_and_collapse= False)

.set_global_opts(title_opts=opts.TitleOpts(title="TitleOpts：标题配置项",subtitle='.set_global_opts(title_opts=opts.TitleOpts())'))

)

c.render_notebook()

2、表格实现：

实现代码：

from pyecharts.components import Table

from pyecharts.options import ComponentTitleOpts

table = Table()

headers = ["属性", "代码", "说明",'举例']

rows = [

["TitleOpts()", 'title= None,','主标题文本，支持使用换行','title=\"标题配置项\"'],

["", 'title_link= None,', '主标题跳转 URL 链接','title_link=\'http://www.baidu.com\', '],

["", 'title_targe= None,','主标题跳转链接方式,默认值blank可选self和blank','title_target=None'],

["", 'subtitle= None,', '副标题文本，支持使用\\n 换行','subtitle=副标题'],

["", 'subtitle_link= None,', '副标题跳转 URL 链接','subtitle_link=\"http://www.baidu.com\"'],

["", 'subtitle_target= None,', '副标题跳转链接方式默认值是blank,可选self','subtitle_target=self'],

["", 'pos_left= None,', '标题离容器左侧的距离,使用数值，百分比或left, center, right','pos_left=\"20%\"'],

["", 'pos_right= None,', '标题离容器右侧的距离,使用数值，百分比或left, center, right','pos_right=\"20%\"'],

["", 'pos_top= None,', '标题离容器上侧的距离,使用数值，百分比或left, center, right','pos_top=\"20%\"'],

["", 'pos_bottom= None,', '标题离容器下侧的距离,使用数值，百分比或left, center, right','pos_bottom=\"20%\"'],

["", 'padding=5,', '标题内边距，单位px，默认各方向内边距为5，接受数组分别设定上右下左边距',' padding= 5 ,\npadding= [50,50,50,50],'],

["", 'item_gap=10,', '主副标题之间的间距',' item_gap=10'],

["", 'title_textstyle_opts= None,', '主标题字体样式配置项，参考 `series_options.TextStyleOpts`','title_textstyle_opts= opts.TextStyleOpts(color="red"),'],

["", 'subtitle_textstyle_opts= None,', '副标题字体样式配置项，参考 `series_options.TextStyleOpts`','subtitle_textstyle_opts= opts.TextStyleOpts(color="blue"),'],

]

table.add(headers, rows)

table.set_global_opts(title_opts=ComponentTitleOpts(title="TitleOpts：标题配置项表格",subtitle='.set_global_opts(title_opts=opts.TitleOpts())'))

table.render_notebook()

3、实例：

实现代码：

from pyecharts import options as opts

from pyecharts.charts import Bar

from pyecharts.faker import Faker

c = (

Bar()

.add_xaxis(Faker.choose())

.add_yaxis("商家A", Faker.values())

.add_yaxis("商家B", Faker.values())

.set_global_opts(

title_opts=opts.TitleOpts(

title= '主标题',

title_link= None,

title_target= None,

subtitle= '副标题',

subtitle_link= None,

subtitle_target= None,

pos_left= None,

pos_right= None,

pos_top=5,

pos_bottom= None,

padding= [5,10,5,10],

item_gap= 30,

title_textstyle_opts= opts.TextStyleOpts(color="red"),

subtitle_textstyle_opts= opts.TextStyleOpts(color="blue"),

)

)

)

c.render_notebook()
