JavaFX 绘制桑基图(SankeyDiagram)
要实现 pyecharts 桑基图的右对齐,可以通过调整图表配置项来实现。具体步骤如下:
1. 导入需要的库和模块:
```python
from pyecharts import options as opts
from pyecharts.charts import Sankey
```
2. 创建桑基图实例对象:
```python
sankey = Sankey()
```
3. 配置图表属性:
这里我们需要调整节点的位置,将节点位置设置为右对齐。可以通过 `pos_right` 参数来实现。同时,还需要设置节点的水平偏移量,这里设置为 50。
```python
sankey.add(
...
label_opts=opts.LabelOpts(
position="right",
offset=50
),
...
)
```
4. 渲染图表:
```python
sankey.render("sankey.html")
```
完整代码示例:
```python
from pyecharts import options as opts
from pyecharts.charts import Sankey
nodes = [
{"name": "A"},
{"name": "B"},
{"name": "C"},
]
links = [
{"source": "A", "target": "B", "value": 10},
{"source": "B", "target": "C", "value": 15},
]
sankey = Sankey()
sankey.add(
"sankey",
nodes,
links,
label_opts=opts.LabelOpts(
position="right",
offset=50
),
linestyle_opt=opts.LineStyleOpts(
opacity=0.2
)
)
sankey.set_global_opts(
title_opts=opts.TitleOpts(title="Sankey-右对齐"),
tooltip_opts=opts.TooltipOpts(trigger="item", trigger_on="mousemove"),
legend_opts=opts.LegendOpts(is_show=False)
)
sankey.render("sankey.html")
```
