# Drawing two curves in the same plot with labels

Hello fellows and folks!

I need to draw the following curve. Could you please give me a hand?

I tried my best the other day but I had serious problems with the labels inside and outside the plot.

Here are the coordinates for train and test:

train: [1.1257, 0.9836, 0.9558, 0.9431, 0.9359, 0.931, 0.9277, 0.9252, 0.9233, 0.9219, 0.9205, 0.9197, 0.9189, 0.9182, 0.9177, 0.9172, 0.9168, 0.9165, 0.9162, 0.9159, 0.9157, 0.9155, 0.9153, 0.9152, 0.915, 0.9149, 0.9147, 0.9146, 0.9145, 0.9143, 0.9143, 0.9142, 0.9141, 0.914, 0.914, 0.914, 0.9139, 0.9138, 0.9137, 0.9137, 0.9136, 0.9136, 0.9136, 0.9136, 0.9135, 0.9134, 0.9134, 0.9134, 0.9133, 0.9132]

test: [1.1257, 0.992, 0.9681, 0.9579, 0.9521, 0.9485, 0.9457, 0.9445, 0.9432, 0.9424, 0.9413, 0.9409, 0.9409, 0.9408, 0.9402, 0.9397, 0.94, 0.9397, 0.9397, 0.9392, 0.9397, 0.9395, 0.9393, 0.9398, 0.9389, 0.9394, 0.9393, 0.9396, 0.9394, 0.9393, 0.9392, 0.939, 0.9389, 0.9394, 0.9393, 0.9385, 0.939, 0.9393, 0.9392, 0.9395, 0.9392, 0.9396, 0.9394, 0.9391, 0.9397, 0.9393, 0.9391, 0.9397, 0.9392, 0.9393]

• @naveganteX Most likely you have set thousands separator={,} somewhere. – user121799 May 17 at 11:05
