前言
本文主要是展示了Pyecharts热力图
的基本应用和简单案例。
一. HeatMap:热力图
1.1 add 函数
主要是:名称,数据,x轴的索引,配置项。
# func pyecharts.charts.HeatMap.add_yaxis
def add_yaxis(# 系列名称,用于 tooltip 的显示,legend 的图例筛选。series_name: str,# Y 坐标轴数据yaxis_data: types.Sequence[types.Union[opts.HeatMapItem, dict]],# 系列数据项value: types.Sequence[types.Union[opts.HeatMapItem, dict]],# 是否选中图例is_selected: bool = True,# 使用的 x 轴的 index,在单个图表实例中存在多个 x 轴的时候有用。xaxis_index: Optional[Numeric] = None,# 使用的 y 轴的 index,在单个图表实例中存在多个 y 轴的时候有用。yaxis_index: Optional[Numeric] = None,# 标签配置项,参考 `series_options.LabelOpts`label_opts: Union[opts.LabelOpts, dict] = opts.LabelOpts(),# 标记点配置项,参考 `series_options.MarkPointOpts`markpoint_opts: Union[opts.MarkPointOpts, dict, None] = None,# 标记线配置项,参考 `series_options.MarkLineOpts`markline_opts: Union[opts.MarkLineOpts, dict, None] = None,# 提示框组件配置项,参考 `series_options.TooltipOpts`tooltip_opts: Union[opts.TooltipOpts, dict, None] = None,# 图元样式配置项,参考 `series_options.ItemStyleOpts`itemstyle_opts: Union[opts.ItemStyleOpts, dict, None] = None,
)
1.2 热力图数据项
主要是:名称,数据项值,提示框配置项
class HeatMapItem(# 数据项名称。name: Optional[str] = None,# 数据项的值。value: Optional[Sequence] = None,# 图元样式配置项,参考 `series_options.ItemStyleOpts`itemstyle_opts: Union[ItemStyleOpts, dict, None] = None,# 提示框组件配置项,参考 `series_options.TooltipOpts`tooltip_opts: Union[TooltipOpts, dict, None] = None,
)
二. 例子
2.1 标签显示
import randomfrom pyecharts import options as opts
from pyecharts.charts import HeatMap
from pyecharts.faker import Fakervalue = [[i, j, random.randint(0, 50)] for i in range(24) for j in range(7)]
c = (HeatMap().add_xaxis(Faker.clock).add_yaxis("series0", # 名称Faker.week, # y轴数据value, # 系列数据label_opts=opts.LabelOpts(is_show=True, position="inside"),).set_global_opts(title_opts=opts.TitleOpts(title="HeatMap-Label 显示"),visualmap_opts=opts.VisualMapOpts(), # 可视组件).render("heatmap_with_label_show.html")
)
2.2 笛卡尔系
这个建议生成 html 看会更有意思。
import pyecharts.options as opts
from pyecharts.charts import HeatMap"""
Gallery 使用 pyecharts 1.1.0
参考地址: https://echarts.apache.org/examples/editor.html?c=heatmap-cartesian目前无法实现的功能:1、官方示例中的 label 暂时无法居中,待解决
2、暂时无法对块设置 itemStyle
