# How does the x coordinates work for plt.bar()? Classic List Threaded 2 messages I am unable to understand how the  plt.bar() function actually works.Take the following code for example:````from` `collections` `import` `Counter` `grades` `=` `[``83``,` `95``,` `91``,` `87``,` `70``,` `0``,` `85``,` `82``,` `100``,` `67``,` `73``,` `77``,` `0``]` `# Bucket grades by decile, but put 100 in with the 90s` `histogram` `=` `Counter``(``min``(``grade` `//` `10` `*` `10``,` `90``)` `for` `grade` `in` `grades``)` `plt``.``bar``([``x` `+` `5` `for` `x` `in` `histogram``.``keys``()],` `# Shift bars right by 5` `histogram``.``values``(),` `# Give each bar its correct height` `10``,` `# Give each bar a width of 10` `edgecolor``=``(``0``,` `0``,` `0``))` `# Black edges for each bar````What does it mean by shift bars by 5 in the plt.bar() call? Does it mean by 5 pixels? 5%? 5% of what? These measurements make no sense. Can someone explain to me how this works?-- Regards,Sreyan Chakravarty _______________________________________________ Matplotlib-users mailing list [hidden email] https://mail.python.org/mailman/listinfo/matplotlib-users
 Five of the same units of your x-axis, which in this case, is points on someone's grade.-PaulOn Fri, Sep 6, 2019 at 12:32 PM Sreyan Chakravarty <[hidden email]> wrote:I am unable to understand how the  plt.bar() function actually works.Take the following code for example:````from` `collections` `import` `Counter` `grades` `=` `[``83``,` `95``,` `91``,` `87``,` `70``,` `0``,` `85``,` `82``,` `100``,` `67``,` `73``,` `77``,` `0``]` `# Bucket grades by decile, but put 100 in with the 90s` `histogram` `=` `Counter``(``min``(``grade` `//` `10` `*` `10``,` `90``)` `for` `grade` `in` `grades``)` `plt``.``bar``([``x` `+` `5` `for` `x` `in` `histogram``.``keys``()],` `# Shift bars right by 5` `histogram``.``values``(),` `# Give each bar its correct height` `10``,` `# Give each bar a width of 10` `edgecolor``=``(``0``,` `0``,` `0``))` `# Black edges for each bar````What does it mean by shift bars by 5 in the plt.bar() call?
