要在Apache Superset中创建动态图表，可以使用Superset的可视化工具，如Slice、Dashboard和Superset API。

以下是一个使用Slice和Superset API创建动态图表的示例代码：

1. 创建一个Slice：

from superset import db
from superset.models import core as models

slice_params = {
    "slice_name": "Dynamic Chart",
    "viz_type": "line",
    "datasource_id": 1,  # 数据源ID
    "params": {
        "metrics": ["count"],
        "groupby": ["date"],
        "time_range": "Last week"
    }
}

slice = models.Slice(**slice_params)
db.session.add(slice)
db.session.commit()

slice_id = slice.id

2. 创建一个Dashboard：

from superset import db
from superset.models import core as models

dashboard_params = {
    "dashboard_title": "Dynamic Dashboard",
    "position_json": {
        "DASHBOARD_VERSION_KEY": "v2",
        "DASHBOARD_ROOT_ID": {
            "id": "DASHBOARD_ROOT_ID",
            "type": "ROOT_ID",
            "children": [
                {
                    "id": "CHART_ID",
                    "type": "CHART",
                    "children": [],
                    "meta": {
                        "width": 4,
                        "height": 50,
                        "chartId": slice_id  # Slice的ID
                    }
                }
            ]
        }
    }
}

dashboard = models.Dashboard(**dashboard_params)
db.session.add(dashboard)
db.session.commit()

dashboard_id = dashboard.id

3. 使用Superset API获取动态图表：

import requests

superset_url = "http://your-superset-url/api/v1/chart/{}/data"
chart_id = slice_id  # Slice的ID

response = requests.get(superset_url.format(chart_id))
data = response.json()

# 处理返回的数据，绘制动态图表

这些代码示例演示了如何使用Apache Superset的Slice、Dashboard和Superset API创建和获取动态图表。您可以根据自己的需求进行修改和扩展。
