ERROR: Could not find a version that satisfies the requirement jupyter-echarts-pypkg==0.1.0 (from pyecharts==0.4.1) (from versions: 0.1.1, 0.1.2, 0.1.4, 0.1.5)

在网页上显示Echarts图表这个问题领域中，该项目与pyecharts的关系，可以和 django-import-export 与 tablib 关系相类似，它们是实现xlsx/xls/csv/json/yaml 文件数据导入导出功能的非常优秀的开源项目。

django-echarts实现了一个通用的架构，在视图类中构建符合功能需求的 pyecharts.base.Base 对象，将其 _option 值（目前未有public的API），直接返回给前端，最后通过
echartsInstance.setOptions(options) 的前端代码完成渲染。

项目着重于后端开发，因为如果需要更加复杂细致的定制需求，显然将这些放在前端 Echarts 是为一个更好的选择。

项目主要开发内容：

• 与Django数据查询的整合
• 与其他功能的整合，尽可能不破坏原有结构
• 其他待定

图表构建函数支持自定义参数，可以根据不同的输入值，加载不同的数据，从而形成多个图表。

以之前的时间轴图表为例子，每次只显示一个年份的数据图表。

@site_obj.register_chart(title='{year}年福建省家庭户类型组成')
def yearly_family(year: int):
    family_types = [
        '一人户', '二人户', '三人户', '四人户', '五人户', '六人户', '七人户', '八人户', '九人户', '十人及其以上'
    ]
    data = [
        [1982, 7.7, 8.2, 12.2, 17.1, 18.4, 14.7, 10.1, 11.6, 0, 0],
        [1990, 5.8, 8.6, 16.8, 23.6, 21.4, 11.8, 5.9, 2.9, 1.4, 1.8],
        [2000, 9.1, 15.5, 25.4, 24.7, 15.8, 5.9, 2.2, 0.8, 0.3, 0.3],
        [2010, 12.1, 17.2, 24.3, 21.7, 13.7, 6.4, 2.6, 1.1, 0.5, 0.4],
        [2020, 27.3, 26.3, 19.4, 14.2, 6.9, 4, 1.1, 0.4, 0.2, 0.2]
    ]
    yearly_data = {item[0]: item[1:] for item in data}
    if year not in yearly_data:
        raise ChartDoesNotExist(f'year={year}')
    year_data = yearly_data[year]
    bar = (
        Bar()
            .add_xaxis(family_types).add_yaxis('百分比(%)', year_data)
            .set_global_opts(title_opts=opts.TitleOpts("福建省家庭户类型构成-{}年".format(year)))
    )
    return bar

说明：

• year为自定义参数，如未声明类型，默认为 str。
• 如果传入的year找不到对应的数据，抛出 ChartDoesNotExist 异常，web页面显示“找不到图表”的页面。
• title参数可以使用类似 {year}的模板字符串。

该图表对应的相关引用配置如下(以year=2020例子)：

关于0.5版本系列

概述

django-echarts v0.5.0将会是新版本系列的第一个正式版本，与原有的0.3.x完全不兼容。

• pypi主页：https://pypi.org/project/django-echarts/
• 文档：https://django-echarts.readthedocs.io/
• 更新日志： https://django-echarts.readthedocs.io/changelog/

使用开发版本

开发版本位于 dev分支，可以通过下面方式安装：

git clone https://github.com/kinegratii/django-echarts.git
cd django-echarts
git checkout -b dev
python setup.py install

现在遇到一种情况就是，我除了要向模板文件中传递图表对象之外，还有一些别的变量要传递过去，那么请问我应该怎么做呢。谢谢。
class NamedChartsView(EChartsBackendView):
...
def get_echarts_instance(self, *args, **kwargs):
....
line = Line()
something = 'something'
return line
比如这里我想把 something 也传递过去。

res = instance.__dict__[self.name] = self.func(instance)

1.在渲染多图表的时候，若添加词云，渲染对应的依赖js的时候，对应的百度资源无法使用，'http://echarts.baidu.com/asset/map/js/wordcloud.js ' 访问报404，也找不到wordcloud.js应该是echarts-wordcloud.mini.js，还望修正公共cdndependencies = merge_js_dependencies(*args) dependencies 为echarts和wordcloud
2. 在获取echarts默认设置时存在无论怎么设置只加载默认DEFAULT_SETTINGS 具体方法为：

def get_django_echarts_settings():
    project_echarts_settings = {k: v for k, v in DEFAULT_SETTINGS.items()}
    project_echarts_settings.update(getattr(settings, 'DJANGO_ECHARTS', {}))
    extra_settings = {
        'STATIC_URL': settings.STATIC_URL
    }
    settings_store = SettingsStore(
        echarts_settings=project_echarts_settings,
        extra_settings=extra_settings
    )
    return settings_store

class SettingsStore(object):
    def __init__(self, *, echarts_settings=None, extra_settings=None, **kwargs):
        # Pre check settings

        self._extra_settings = extra_settings or {}
        if  self._extra_settings.get('lib_js_host') == 'local_host':
            self._extra_settings['lib_js_host'] = echarts_settings['local_host']
        if  self._extra_settings.get('map_js_host') == 'local_host':
            self._extra_settings['map_js_host'] = echarts_settings['local_host']

        # Merge echarts settings
        self._settings = {**DEFAULT_SETTINGS, **self._extra_settings}

上述self._extra_settings的值一直是

extra_settings = {
        'STATIC_URL': settings.STATIC_URL
    }

我觉着如果本地有仓库的话应该为：

        if  echarts_settings.get('lib_js_host') == 'local_host':
            self._extra_settings['lib_js_host'] = echarts_settings['local_host']
        if  echarts_settings.get('map_js_host') == 'local_host':
            self._extra_settings['map_js_host'] = echarts_settings['local_host']

DJANGO_ECHARTS = {
    'echarts_version': '4.0.4',
    'renderer': 'svg',
    'lib_js_host': 'local_host',
    'map_js_host': 'local_host',
    'local_host': '/static/js' 本地设置
}

烦请您查看一下，如有误解，还望解答。谢谢

我使用快速开始的代码，但是我的第一个网页的“福建统计”始终echarts显示，我是用linux和mac进行了实验，都不显示

Based on these:

1. Django 1.11 is a LTS version and many developers still use it.
2. Django 2.0 has no more breakdown change except python2 support with 1.11 .

1 运行环境支持

django-echarts v0.6.0默认使用 pyecharts 2.x 作为底层渲染库，其最大的变化是 echarts 版本由 4.8 升级至 5.4。

django-echarts 依赖库更新如下：

pyecharts 1.9 -> 2.0
typing_extensions 4.0 -> 4.5
borax 3.5 -> 4.0

2 图表构建函数支持自定义参数

图表构建函数支持自定义参数，可以根据不同的输入值，加载不同的数据，从而形成多个图表。

以之前的时间轴图表为例子，每次只显示一个年份的数据图表。

@site_obj.register_chart(title='{year}年福建省家庭户类型组成')
def yearly_family(year: int):
    family_types = [
        '一人户', '二人户', '三人户', '四人户', '五人户', '六人户', '七人户', '八人户', '九人户', '十人及其以上'
    ]
    data = [
        [1982, 7.7, 8.2, 12.2, 17.1, 18.4, 14.7, 10.1, 11.6, 0, 0],
        [1990, 5.8, 8.6, 16.8, 23.6, 21.4, 11.8, 5.9, 2.9, 1.4, 1.8],
        [2000, 9.1, 15.5, 25.4, 24.7, 15.8, 5.9, 2.2, 0.8, 0.3, 0.3],
        [2010, 12.1, 17.2, 24.3, 21.7, 13.7, 6.4, 2.6, 1.1, 0.5, 0.4],
        [2020, 27.3, 26.3, 19.4, 14.2, 6.9, 4, 1.1, 0.4, 0.2, 0.2]
    ]
    yearly_data = {item[0]: item[1:] for item in data}
    if year not in yearly_data:
        raise ChartDoesNotExist(f'year={year}')
    year_data = yearly_data[year]
    bar = (
        Bar()
            .add_xaxis(family_types).add_yaxis('百分比(%)', year_data)
            .set_global_opts(title_opts=opts.TitleOpts("福建省家庭户类型构成-{}年".format(year)))
    )
    return bar

说明：

• year为自定义参数，如未声明类型，默认为 str。
• 如果传入的year找不到对应的数据，抛出 ChartDoesNotExist 异常，web页面显示“找不到图表”的页面。
• title参数可以使用类似 {year}的模板字符串。

该图表对应的相关引用配置如下(以year=2020例子)：

2 新增声明式导航栏配置

django-echarts 0.6 新增了使用字典方式一次性配置导航栏配置。

# site_config.py

nav_config = {
    'nav_left': ['home', 'list'],
    'nav_right': ['settings'],
    'nav_footer': [
        {'text': '项目主页', 'slug': 'project_url', 'url': 'https://github.com/kinegratii/django-echarts'}
    ]
}

# urls.py

site_obj.config_nav(nav_config)

3 DJESite类移除导航栏相关方法

可使用 DJESite.nav 相关方法，参见下面的Nav API章节。

• DJESite.add_left_link
• DJESite.add_right_link
• DJESite.add_footer_link
• DJESite.add_menu_item

4 ChartInfo和ChartInfoManager

• 类 ChartInfo 增加 is_bound 布尔值属性，如果对应图表注册函数携带任何参数，则设置为 False，数据格式化后变为True。
• ChartInfoManagerMixin.get_or_none 增加 uri 参数。
• 在 is_bound = False 情况下，body title description的转义处理

多个地图同时渲染时，数据视图里面会出现除经纬度外的多个值，且tooltip点击对应城市，上方显示的值竟然是纬度值。
问题应该是因为echarts里默认图像不合并，前面渲染的数据未被覆盖或清空。
按照参考的代码把其他的都做出来了，但是多地图这一块一直没有找到好的解决方案。
之前又看到设置EchartInstance.clear或者myechart.setOption(option,true)之类的方法，试过在{% block extra_script %}里面写{% echart_instance.clear %}但是没有效果。
请问，这个问题怎么解决比较好呢？

另外，echart_instance.page_title可以显示出来，请问，有没有获取echart_intance对应的name和value的方法呢？

pyechart如何在line图上显示百分数

比如有节点和节点之间的关系，并且可以动态拖动的

django-echarts 的 requirements.txt 文件 不包含 pyecharts 和 django 两个库，请阅读以下文字后，选择安装 django-echarts。

注意 django-echarts 暂未适配 pyecharts v0.5.x ，敬请期待。

pyecharts

请根据你的 pyecharts 版本安装 django-echarts 。

Python & Django

django-echarts 只支持 ：

• Python3.5+
• Django 1.11 LTS 或 Django 2.0+

安装方式

可以使用 pip 在线安装。

pip install django-echarts

或者使用源码构建

git clone https://github.com/kinegratii/django-echarts.git
cd django-echarts
python setup.py install

访问 http://127.0.0.1:8000/demo/temperature/ 报递归错误

Request Method: | GET
-- | --

RecursionError

E:\projects\django-echarts\django_echarts\views\backend.py in get_context_data, line 13

相关代码

为因应上游库（pyecharts）的变化:

• pyecharts v0.3.2+ ，地图文件独立打包和发行
• pyecharts 地图管理 API 相对封闭

以及django-echarts 的存在的问题：

• django-echarts 未实现 pyecharts 地图管理的若干功能
• django-echarts 对于相关概念的混用

需要针对 JS 文件托管功能进行重构。遵循的主要原则：

• 由于web 项目的特点，django-echarts 认为 js 基于项目，这一点和 pyecharts 是最大的不同。
• django-echarts 本身不托管任何 js 文件，如若提供，仅作为一个样例存在，不具有通用性

重构和强化的内容包括：

• 重新理顺相关数据处理过程
• 提供更为强大的配置以因应大多数的使用场景
• 重命名部分不合功能和实际的变量、函数、类名称
