Edit xticks of a histogram in Python

  • 772

I have to edit the xticks of a histogram that I have painted with .plot, the xticks represent the months in datetime. I would like to display the months, I have tried using a list.

listaMeses = ['Enero', 'Febrero', 'Marzo', 'Abril', 'Mayo', 'Junio', 'Julio', 'Agosto', 'Septiembre', 'Octubre', 'Noviembre', 'Diciembre'] 

histograma2021 = df_logsFinalizados2021.plot(kind='bar', title = 'Histograma 2021 de viajes por mes')
histograma2021.set(xlabel='Número de viajes', ylabel = 'Mes donde finalizó el viaje', xticks = listaMeses)

I get the following error:

ConversionError: Failed to convert value(s) to axis units: ['Enero', 'Febrero', 'Marzo', 'Abril', 'Mayo', 'Junio', 'Julio', 'Agosto', 'Septiembre', 'Octubre', 'Noviembre', 'Diciembre']

Attached image of the histogram.

I don't know if it's a misconception or if I'm close to the goal.

Thanks in advance!

    You have to change the last line of your code, removing the reference to xticks, and add a line specifying what you want to put, and where.

    According to the official matplotlib documentation, the correct way to use xticks is: xticks([lista-posiciones], [lista-etiquetas]). The code would look like this:

    histograma2021.set(xlabel='Número de viajes', ylabel = 'Mes donde finalizó el viaje')
xticks([1,2,3,4,5,6,7,8,9,10,11], listaMeses)

    Note that your histogram only has 11 months in the data, so you have to match the list of months to the xticks... you have December left over.

    Edit: matplotlib was not used. I mistakenly thought another python module was being used. If you are using pandas , the correct answer would be to add this line of code:

    histograma2021.set_xticklabels(listaMeses)
