# How change x labels data in ListLinePlot?

How to change the x data/label units? typing "exam 1", "exam 2", "exam 3",... instead of 1, 2, 3, ...

notas = {{6.3, 5.2, 4.70, 8.70, 3.05}, {8.95, 6.25, 7.20, 8.20,
8.5}, {4.95, 2.15, 2.80, 3.70, 2.4}, {5.7, 4.6, 4.80, 3.85,
3.25}, {0.65, 0.3, 0.05, 0.10, 0.1}, {4.1, 1.7, 0.30, 0.10,
0.1}, {2.05, 1.05, 1.55, 0.20, 1.75}, {5.5, 6.6, 5.25, 8.10,
8.6}, {6.2, 7.5, 9.45, 6.30, 8.4}, {3.95, 4.35, 7.85, 5.90, 1.25}}

a = ListLinePlot[notas, ImageSize -> Large,
PlotStyle -> AbsoluteThickness[1.6], LabelStyle -> {20, Bold} ,
AxesOrigin -> {1, 0},
GridLines -> {{1, 2, 3, 4, 5, 6, 7, 8, 9}}]

• Have a look at the documentation for Ticks. – b.gates.you.know.what Feb 11 '18 at 9:03
• @b.gatessucks Tells me that "A tick position should be a number" – Mika Ike Feb 11 '18 at 9:05

Ticks -> {

Note that the Automatic is there to manage the ticks on the $y$ axis.
Also note that the first tick is disappearing due to the positioning of the $y$ axis, which takes priority over it. This can potentially be avoided by switching to FrameTicks -> (*same*), Frame-> True.
