I am doing a very basic operation — drawing dots in Mathematica. Here’s the code:
Graphics[
{
Point[{0, 0}], Point[{1, 2}]
}
]
I gives the result that I wanted:

But when I specified the “PlotRange”, I then got a blank canvas. Why the two dots disappeared?
Graphics[
{
Point[{0, 0}], Point[{1, 2}]
},
PlotRange -> {{0, 0}, {4, 4}}
]

If you cannot reproduce the problem I encountered, please also let me know. Thank you.
The option PlotRange was used wrong. You have to give the corners of the rectangular plot-range in this order
{{xmin, xmax}, {ymin, ymax}}.In your case
