I'm having trouble saving histogram plots from a "for loop" into multiple pdf files.

I have tried the .savefig() and the img2pdf. 

for i,title in enumerate(titles):
    count, bins, ignored = plt.hist(dists[i], 50, normed=True, range= 
    [450,1700])
    plt.title(title)
    plt.xlabel("g CO2-eq/day-bed " )
    plt.ylabel("Frequency")
    plt.show()

    plt.savefig[i]("nitrileglob1.pdf",bbox_inches='tight')

I either save one plot or none of them get saved. I want to save each of the dists[i] into a pdf file. The last line is not really working...

The problem is that you are saving all of your plots under the same name. You would have to change the file name in each iteration, for example 

plt.savefig("nitrileglob" + str(i) + ".pdf",bbox_inches="tight")

You should also save the file before calling plt.show(), as this clears the current figure.
