python - How to display all label values in matplotlib?

Question

I have two lists, when I plot with the following code, the x axis only shows up to 12 (max is 15). May I know how can I show all of the values in x list to the x axis? Thanks in advance.

x = [4,5,6,7,8,9,10,11,12,13,14,15,0,1,2,3]
y = [10,20,30,40,50,60,70,80,90,100,110,120,130,140,150,160]
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax1.plot(np.arange(len(x)), y, 'o')
ax1.set_xticklabels(x)
plt.show()

If I set minor=True in the set_xticklabels function, it shows me all x=2,4,6,8,..,16... but I want ALL values.

P.S. My x axis is not sorted, should display as it shows.

Answer 1

The issue here is that the number of ticks -set automatically - isn’t the same as the number of points in your plot.

To resolve this, set the number of ticks:

ax1.set_xticks(np.arange(len(x)))

Before the ax1.set_xticklabels(x) call.
