在Python中,你可以利用`pyecharts`库创建丰富的图表,并结合`Timeline`模块来展示时间轴。`Timeline`通常用于动态地显示数据随时间的变化情况。以下是一个基本的例子,展示了如何使用`pyecharts`生成折线图并结合`Timeline`来构建时间线和Tab组件的组合:
```python
from pyecharts import options as opts
from pyecharts.charts import Line, Timeline
from pyecharts.faker import Faker
# 创建初始数据
data = [{"name": f"数据点{i}", "value": Faker.values(), "time": i} for i in range(10)]
# 初始化Line图表和Timeline
line_chart = (
Line()
.add_xaxis(["time" for _ in data])
.add_yaxis("系列名称", [d["value"] for d in data], label_opts=opts.LabelOpts(is_show=False))
)
timeline = Timeline().add_charts(line_chart)
# 将时间序列添加到Timeline上
for idx, item in enumerate(data):
timeline.add_schema(chart=line_chart, key=item["time"], is_first=(idx == 0), is_last=(idx == len(data) - 1))
# 结合Tab组件输出HTML
tabs = [
{
"content": line_chart.render_embed(),
"title": f"时间戳 {i}",
}
for i in sorted({d["time"] for d in data})
]
timeline_options = {"width": "100%", "height": "400px"}
timeline_html = timeline.render(tabs=tabs, option=timeline_options)
# 输出HTML
with open('output.html', 'w', encoding='utf-8') as f:
f.write('<div id="chart-container"></div>')
f.write(f'<script type="text/javascript">{timeline_html}</script>')
