![]() ![]() Mdates.DayLocator() adds a tick for each day. But if you wanted to add day ticks to a plot that did have minor ticks turned “on” you would use:Īx.t_minor_locator(mdates.DayLocator()) Given we are using seaborn to customize the look of our plot, minor ticks are not rendered. You can add minor ticks to your plot too. WeekdayLocator ( interval = 2 )) Scatterplot showing daily precipitation with the x-axis dates cleaned up and the format customized so they are easier to read. set_major_formatter ( date_form ) # Ensure ticks fall once every other week (interval=2)Īx. set ( xlabel = "Date", ylabel = "Precipitation (Inches)", title = "Daily Precipitation (inches) \n Boulder, Colorado 2013" ) # Define the date formatĭate_form = DateFormatter ( "%m/%d" ) ax. ![]() This applies the date format that you defined above to the plot.įig, ax = plt. Then you call the format that you defined using the set_major_formatter() method. Here you can customize the date to look like whatever format you want. It needs two arrays of the same length, one for the values of the x-axis. This a date format that is month/day so it will look like this: 10/05 which represents October 5th. With Pyplot, you can use the scatter() function to draw a scatter plot. To implement the custom date, you then: define the date format: myFmt = DateFormatter("%m/%d") How to plot dates on the x-axis with Python’s matplotlib To plot dates on the x-axis with Python’s matplotlib, we convert the date strings to datetime objects with strptime. In this article, we’ll look at how to plot dates on the x-axis with Python’s matplotlib. Make a list of dates and convert them in datetime format as x. Sometimes, we want to plot dates on the x-axis with Python’s matplotlib. %Y - 4 digit year %y - 2 digit year %m - month %d - day To plot data against specific dates on the X-axis using matplotlib, we can take the following steps Set the figure size and adjust the padding between and around the subplots. Then you specify the format that you want to use for the date DateFormatter using the syntax: ("%m/%d") where each %m element represents a part of the date as follows: To begin you need to import DateFormatter from matplotlib. You can change the format of a date on a plot axis too in matplotlib using the DateFormatter module. show () Scatterplot showing daily precipitation in Boulder, Colorado. set_major_formatter ( DateFormatter ( "%m-%d" )) plt. Example 1 : In this example, we will be setting up the X-Axis Values in Matplotlib using the xtick () function in the python programming language. set ( xlabel = "Date", ylabel = "Precipitation (Inches)", title = "Daily Precipitation \n Boulder, Colorado 2013" ) # Format the x axisĪx.
