Python Altair how do I skip (or squeeze) part of the x axis?-CodePudding

Say I have data indexed by date time (pd.Timestamp type), but I know for certain that between certain times each day, there is no data (financial data for example), and I would like to plot data over several days but I want to skip the night times and only draw the day times, so that from one day to the next there isn't a huge gap (of night time) on the x-axis. Is it possible to do that?

CodePudding user response：

You can use the same approach as in this answer for VegaLite (

This is what it would have looked like on a temporal axis, note the long connecting lines without dots which are the night periods:

alt.Chart(pd.DataFrame(records), width=650).mark_line(point=True).encode(
    x=alt.X('yearmonthdatehours(Date):T', axis=alt.Axis(labelAngle=-45)),
    y=alt.Y('Close', scale=alt.Scale(zero=False))
)
