F1 score graph skewed The following code

DBSCAN_score = pd.read_csv("DBSCAN_scores.csv")
sigmoid_score = pd.read_csv("Sigmoid_scores.csv")

score = pd.concat([sigmoid_score.F1_score.fillna(0), DBSCAN_score.F1_score.fillna(0)], axis=1)
score.columns = ["Sigmoid", "DBSCAN"]
ax = plt.gca()
ax.set_title("F1 score comparison")
score.plot(ax=ax)
plt.show()


Normaly I would get the output bellow


Now I am getting the following result with the same code and the same files.
I'm struggling to make it look like the output above
The way I see it is because some reason your x limits is different, you could try:

plt.xlim(0,120)
