Sorry if this is the wrong category, but please I really need your help! I suck so much in excel, but I have to make a chart that looks like this, but using my own set of data.
I know its probably not too difficult, but I'm just so bad in excel and I do have to turn it in today. It would mean so much for me if someone could help me out quickly! Otherwise please tell me where I should post this

My data set:
x-axis: 3977 / 10716 / 13141
y-axis: Left side is the same, Right side needs to go up to 10 000
Black line: 0 / 7390 / 9062
Red line: 1178 / 1559 / 2346
Yellow line: 974 / 941 / 956

All help is very much appreciated! Dont bother too much with the axis titles and such if you dont want too, I really care mostly about the lines of my data represented like this

Just found this and it certainly takes the cake for me. Look at the comments. https://youtu.be/puDtgsPGpZI
