Bar plot with plotly grouped and stacked as is

Question

My input:

    df=(pd.DataFrame({'label_color':['white','white','cyan','cyan','cyan','cyan','white','white'],
                  'label_quality':['white','white','red','green','green','red','white','white'],
'label':['foo','foo','foo','foo','foo','foo','foo','foo']}))

Let me explain what I want: "One column" will be label color and "Second column" will be label_quality, where x.axis is df.index and correlated position columns with order of index. Also y.axis is just name of label. And colors is values from df columns["label_colors ","label_quality"]

Here solution that provide @r_beginners:

df['color_value'] = 1
df['quality_value'] = 1

fig = px.bar(df, y=['color_value','quality_value'],
             x=[1]*len(df),
             orientation='h',
             barmode='group',
             template='plotly_white')

fig.data[0]['marker']['color'] = df['label_color'].tolist()
fig.data[1]['marker']['color'] = df['label_quality'].tolist()
fig.update_traces(marker_line_color='rgb(8,48,107)')
fig.update_layout(showlegend=False, yaxis_title='foo', xaxis_title='')
fig.show()

But ion real data its looks some strange:

seems like that column borders overlapped:

I find solution: fig.update_traces(marker_line_color='rgb(255,255,255)', marker_line_width=0 )

So:

Hope it will be helpful anyone who want visualization data

The data you presented does not match the content of the x-axis of the graph, but in order to achieve what you want, you need to add values for each of them, because you cannot draw a graph with just the color names. In addition, after completing the horizontal bar graph, I have updated the list of columns with the desired colors. The color of the border is changed to determine whether it is blank or white with respect to color. Depending on the purpose of the graph, a Gantt chart may be preferable to a timeline.

df['color_value'] = 1
df['quality_value'] = 1

fig = px.bar(df, y=['color_value','quality_value'],
             x=[1]*len(df),
             orientation='h',
             barmode='group',
             template='plotly_white')

fig.data[0]['marker']['color'] = df['label_color'].tolist()
fig.data[1]['marker']['color'] = df['label_quality'].tolist()
fig.update_traces(marker_line_color='rgb(8,48,107)')
fig.update_layout(showlegend=False, yaxis_title='foo', xaxis_title='')
fig.show()
