axis scaling in 2D line plot

[c-humbel]

Hi,
A very simple question, but I didn't find an answer in the documentation: Is there a way to get equal scaling of the x- and y-axis in a line plot?
For a student project, i had to plot sine vs. cosine, and I would like the plot to look like a circle and not an ellipse.
circle.pdf
Matplotlib has a function set_aspect() that achieves this, is there something similar for matplot++?
The code I used is very simple, but for completion I post it anyway:

double t = 0;
double dt = 2*M_PI / size;
for (unsigned i = 0; i < size; ++i) {
    x[i] = std::sin(t);
    y[i] = std::cos(t);
    t += dt;
}
matplot::plot(x, y);
matplot::save("circle.pdf");

Maybe one of these functions can help you:

matplotplusplus/source/matplot/core/axes_type.h

Line 106 in 7fd8c9e

void axis(keyword_equal_type);

Thanks a lot, this worked!
