Bar chart with very thin bars

[gabino.alonso]

Hello all,
my problem is that when I view my bar chart, the bars appear very thin and you can hardly see them.

i have this >>

and this is my sample code:

df_test = pd.read_csv('test_data.csv')
media = round(df_test["ok"].mean())
title = "Cantidad por producciones (OK medio = {})".format(media)
fig = px.bar(df_test,
                x = 'inicio',
                y="ok",
                hover_data=['id', 'inicio', 'ok', 'nok'],
                color='maquina',
                title=title)

fig.add_hline(y=media, line_color='darkblue', line_width=2, line_dash="dot", opacity=0.5)

fig.update_layout(showlegend=True,
                      hoverlabel_align = 'right',
                      xaxis_title= None,
                      yaxis_title= None,
                      hovermode="x unified",
                      plot_bgcolor="#f9f9f9",
                      paper_bgcolor="#f9f9f9",
                      margin=dict(l=30, r=0, t=30, b=10)
    )

Hey @gabino.alonso

Try experimenting with the width property of the bar component.

fig.update_traces(width=1)

It should work… If not, do not hesitate to ask again!

Cheers!

How to limit bar width with time-series axis

Hi, you have a strange way of putting your Figure together mixing up plotly.express and plotly.graph_objects Here is how I would do this, the width parameter is what you are looking for. Since you are using a time axis, the width has to be specified in milliseconds: from pandas import DataFrame import plotly.graph_objects as go dtf = DataFrame({"hour": ["2023-07-10 17:00:00+08:00", "2023-07-10 21:00:00+08:00"], "number": [2, 5]}) fig = go.Figure(go.Bar(x=dtf.hour, y=dtf.number, width=3_600_0…

Unstacking grouped plot creates huge gap between groups. PlotlyExpress

Hey peeps! As you can see from the first image my plot is nice and readable, but i’d like to unstack these to be able to easier seperate things. But when i do the gap between the groups becomes huge, i’ve tried searching the forums and google but i’m not able to find any result… I have tried bargap and bargroupgap without any difference, both in “update_layout” and directly in the plot.

Thanks to both of you, I’m going to try it and share my experience.
