problem of axis accuracy. rounding values

[antoinech13]

Hello, i encounter a little problem.

I try to do a simple plot(x, y) where x and y are two std::vector<double> (values of x are looking like 58539.1659 and y look like 16.152)

my problem is when i pass this vectors to the plot function. The graphe produced have rounded axis.

as exemple, imagine my data set is:

x = { 58539.1489, 58539.1235, 58539.1659, 58539.1786, 58539.19161, 58539.2055}

then all values will be stack on 58539.1 and 58539.2.

for y axis is the same but the rounding is more accurate.
That also happen when i try to display with cout function the content of this vector but in this case, std::setprecision allow me to display it well.

I also used the variable explorer with some breaking points to check x and y and this vectors are not rounded.

So how can i do something similar to what do stprecision for cout but for matplot++?

thank you in advance.

ps: i use vs2022 under windows.
