Through a panel of 2 lists make a chart

Question

I have 1 table with 2 lists as for example the following ones , where the first one contains dates in the YYYYMMDD format and the second one contains the number of times a crime happened that day.

tuplo= (['20160130', '20160230', '20160330', '20160430', '20160530', '20160730'] [1, 2, 2, 2, 1, 1])

What I intend to do is a function that shows a graph with the number of crimes that occurred each day, and abscissas correspond to the years and ordered to the number of crimes.

def fazer_grafico(tuplo):

    x = list()
    for anos in tuplo[0]:
        x.append(anos[:4])
     # x é uma lista só com os anos

    x_tmp = range(0, len(x), len(x)/len(set(x)))
    y= grafico[1]


    pylab.plot(range(len(x)), y)
    x= sorted(set(x))
    x.append(" ")
    pylab.xticks(x_tmp,sorted(set(y)))

The function is doing the correct chart however it does only one thing that is my doubt, what I can do and then change in my code so that the abscissas in this case the x , take into account the years with 365 and 366 days , because supposedly with 365 the axis width will be smaller and with 366 will be bigger

Answer 1

Instead of creating x_tmp like this:

x_tmp = range(0, len(x), len(x)/len(set(x)))

Create according to the year in question. Know that if the year is leap is divisible by 4, otherwise it is not, for example:

x_tmp = [0]
Para cada ano de sorted(set(x)):
    Se ano bissexto:
        adicionar 366 à ultima entrada de x_tmp e fazer append a x_tmp
    Caso contrário:
        adicionar 365 à ultima entrada de x_tmp e fazer append a x_tmp

I think that will have the list with the number of days that passed to the year in question.
