How do I add statistical annotations, e.g. p-values, to graphs? For example: [newplot-20] Code for bar graph without statistical annotations: import plotly.graph_objects as go import pandas as pd df = pd.read_csv('https://raw.githubusercontent.com/mwaskom/seaborn-data/master/tips.csv') days=[…

I now made this graph below; how can I place the p-value p=0.00156 specified as fig.add_trace(go.Scatter( x=['day1 and day 2'], y=[26], mode="text", name="p-value", text=['p=0.00156'], textposition="top center", showlegend=False )) in the middle, i.e. between day1 and d…

@Alexboiboi and @nicolaskruchten do you perhaps have a suggestion for this? Or should I simply use another program to depict brackets and p-values?

Hi @windrose , you can work with shapes instead of adding a trace just draw a line. Something like fig.add_shape(type="line" ... see here for more infos: [image] Shapes How to make SVG shapes in python. Examples of lines, circle, rectangle, and path.

Here’s a code that accomplishes fairly well what I want; may there is better solution? import plotly.graph_objects as go import pandas as pd df = pd.read_csv('https://raw.githubusercontent.com/mwaskom/seaborn-data/master/tips.csv') days=['day1 and day 2', 'day 3 and day 4'] # Group and calculate…

Please see also Scatter plot with conditional error bars I hope that adding p-values and their brackets will be made easier in the future.

Absolute text/annotation positioning can be achieved in categorical plots, see here Free text positioning in categorical graph?. In this case the annotation/text will stay put, of course.
