Model

Create Vertical Barchart stacked

def create_barchart(df, label, groups, value, title):
fig = go.Figure()
list_groups = df[groups].unique()
for group in list_groups:
tmp_df = df[df[groups] == group]
fig.add_trace(go.Bar(x=tmp_df[label],
y=tmp_df[value],
name=group))
fig.update_layout(
title=title ,
plot_bgcolor="#ffffff",
width=1200,
height=800,
xaxis_tickfont_size=14,
legend=dict(
bgcolor='white',
bordercolor='white'
),
barmode='group',
bargap=0.1, # gap between bars of adjacent location coordinates.
bargroupgap=0.1 # gap between bars of the same location coordinate.
)
config = {'displayModeBar': False}
fig.show(config=config)
return df
fig = create_barchart(df, label="LABEL", groups="GROUPS", value="VALUE", title=title)

Output

Export in PNG and HTML

fig.write_image(output_image, width=1200)
fig.write_html(output_html)

Generate shareable assets

link_image = naas.asset.add(output_image)
link_html = naas.asset.add(output_html, {"inline":True})
#-> Uncomment the line below to remove your assets
# naas.asset.delete(output_image)
# naas.asset.delete(output_html)
