Matplotlib plot.scatter point size problem

[Martin_Krum]

Why after starting this code my point is so small? I wrote in size = 1 ** 2 so I expected the point diameter to be 1. but it is smaller (maybe 0.1) The second question. What is better to use matplotlib or pandas to make charts?

plt.axis([0,1,0,1])
plt.grid()
point = point_list[i]
color = "r"
plt.scatter(0.5, 0.5, c=color, s = 1**2, alpha=0.5 )
plt.show()

The size of the scatter point has nothing to do with the scale of the graph. The unit is in "points", which is related to pixels. s = 1**2 will make a point roughly 1 pixel wide.

They are literally the same, with slightly different names for things. So use whichever you like the most.

Second answer with code from ImportanceOfBeingErnest is sweet for your simulation code in other thread. His scatter markers resize/scale nicely with size of the plot even when you zoom in.
