I'm trying to plot the data of my DataFarme in a groupedChart and I want the columns to preserve the order I gave them before. The data looks as follows (its not all there but its in the same way organized) dataframe
When I plot it I get the following Graph: graph
So the months were sorted even though I specified not to sort in the chart. I used the following code:
chart2 = alt.Chart(melted).mark_bar().encode(
column=alt.Column('variable',sort=None),
x=alt.X('room',sort=None),
y=alt.Y('value'),
color='room',
tooltip= ['room', 'value']
)
Does anyone know how I could fix that?

You've already used sort=None
, which is the correct way to make scales in a non-faceted chart reflect the input order.
The missing piece is that faceted charts share scales by default (See Scale and Guide Resolution), so each facet is being forced to share an order.
If you make the x scale resolution independent, then each facet should retain the input order:
chart2 = alt.Chart(melted).mark_bar().encode(
column=alt.Column('variable',sort=None),
x=alt.X('room',sort=None),
y=alt.Y('value'),
color='room',
tooltip= ['room', 'value']
).resolve_scale(x='independent')
