Hello. I have a dataset that creates a nice scatter plot:
However, I would like there to be a line that connects the lowest y values across time.
This is an example of what I mean:
Is there a way to do this with plotly express?
Hi @nogons welcome to the forums.
Yes, you can do that. You just have to add a trace with the minimum values:
import numpy as np
import plotly.express as px
# create data
arr = np.random.randint(0, 2000, size=(10, 30))
# create base figure
fig = px.scatter(arr)
# formatting
fig.update_traces(
showlegend=False,
marker_color='black',
marker_size=8
)
# add trace with minimum values
fig.add_scatter(
x=[*range(10)],
y=np.min(arr, axis=1),
name='minumum',
marker_color='red',
marker_symbol='circle-open',
marker_size=11
)
# layout
fig.update_layout(height=700, width=700)
fig.show()
