pyecharts桑基图link颜色设置

Pyecharts 的桑基图(Sankey)可以通过修改 `set_edge` 方法中的 `links` 参数来设置每个链接的颜色。具体的做法是,在 `set_edge` 方法中传入一个包含 `source`、`target` 和 `value` 三个元素的字典列表,再为每个链接添加一个 `color` 属性即可。
以下是一个示例代码:
```python
from pyecharts.charts import Sankey
nodes = [{"name": "A"}, {"name": "B"}, {"name": "C"}]
links = [
{"source": "A", "target": "B", "value": 10, "color": "blue"},
{"source": "B", "target": "C", "value": 5, "color": "red"},
{"source": "A", "target": "C", "value": 15, "color": "green"}
]
sankey = Sankey()
sankey.add("Sankey", nodes, links, linestyle_opt={"curve": 0.5, "opacity": 0.5})
sankey.set_edge(links)
sankey.render("sankey.html")
```
在上述代码中,我们通过将每个链接的 `color` 属性设置为不同的颜色,来实现桑基图中每个链接的颜色不同的效果。

pyecharts桑基图边颜色设置
在 Pyecharts 中,可以通过 `set_edge_item` 方法来设置桑基图的边的颜色。具体来说,可以通过以下代码来实现:
```python
from pyecharts import options as opts
from pyecharts.charts import Sankey
sankey = Sankey()
nodes = [
{"name": "a"},
{"name": "b"},
{"name": "c"},
{"name": "d"},
{"name": "e"}
]
links = [
{"source": "a", "target": "b", "value": 10},
{"source": "b", "target": "c", "value": 15},
{"source": "c", "target": "d", "value": 20},
{"source": "d", "target": "e", "value": 25}
]
sankey.add(
series_name="",
nodes=nodes,
links=links,
linestyle_opt=opts.LineStyleOpts(opacity=0.2, curve=0.5, width=10),
label_opts=opts.LabelOpts(position="right"),
).set_global_opts(
title_opts=opts.TitleOpts(title="Sankey Diagram"),
tooltip_opts=opts.TooltipOpts(trigger="item", trigger_on="mousemove"),
).set_series_opts(
label_opts=opts.LabelOpts(position="right"),
# 设置边颜色
linestyle_opts=opts.LineStyleOpts(color="#333", opacity=0.8, curve=0.5, width=10)
)
sankey.render("sankey.html")
```
其中,`linestyle_opts` 参数可以用来设置边的样式,包括颜色、透明度、曲度和宽度等。在这里,我们将边的颜色设置为 `#333`。
pyecharts桑基图节点颜色
要设置桑基图节点的颜色,可以在 `Sankey.add` 方法中通过参数 `node_color` 来指定节点的颜色。例如:
```python
from pyecharts import options as opts
from pyecharts.charts import Sankey
nodes = [
{"name": "A"},
{"name": "B"},
{"name": "C"},
{"name": "D"},
{"name": "E"}
]
links = [
{"source": "A", "target": "B", "value": 10},
{"source": "A", "target": "C", "value": 15},
{"source": "B", "target": "D", "value": 12},
{"source": "C", "target": "D", "value": 8},
{"source": "D", "target": "E", "value": 20}
]
sankey = Sankey()
sankey.add(
"sankey",
nodes,
links,
node_gap=30,
node_width=20,
node_label_opts=opts.LabelOpts(position="right"),
linestyle_opt=opts.LineStyleOpts(opacity=0.2),
label_opts=opts.LabelOpts(font_size=14),
node_color=["#FFB6C1", "#87CEFA", "#90EE90", "#FFC0CB", "#ADD8E6"]
)
sankey.render("sankey.html")
```
在 `node_color` 参数中传入一个列表,每个元素对应一个节点的颜色,节点的顺序与传入的 `nodes` 列表一致。
