I have not been using Mathematica for some time. I did quite complex things in the past. But today I met a trivial one.
data = {
{22.74, 26.45},
{22.91, 26.95},
{23.08, 29.20},
{23.13, 27.19},
{23.25, 26.60}
};
Show[ListPlot[data]]
How many point do you account on the plot ? I see only 4 points. Now pls do (I update the y of the 3rd number):
data = {
{22.74, 26.45},
{22.91, 26.95},
{23.08, 29.00},
{23.13, 27.19},
{23.25, 26.60}
};
Show[ListPlot[data]]
In this case I see 5 points, the 3rd appears !!
Please let me again thrust this language.
