Why is set_xlim() not setting the x-limits in my figure?

Question

I'm plotting some data with matplotlib. I want the plot to focus on a specific range of x-values, so I'm using set_xlim().

Roughly, my code looks like this:

fig=plt.figure() ax=fig.add_subplot(111) for ydata in ydatalist:     ax.plot(x_data,y_data[0],label=ydata[1]) ax.set_xlim(left=0.0,right=1000) plt.savefig(filename) 

When I look at the plot, the x range ends up being from 0 to 12000. This occurs whether set_xlim() occurs before or after plot(). Why is set_xlim() not working in this situation?

Answer 1

Out of curiosity, what about switching in the old xmin and xmax?

fig=plt.figure() ax=fig.add_subplot(111) ax.plot(x_data,y_data) ax.set_xlim(xmin=0.0, xmax=1000) plt.savefig(filename)
