Why is the following code not plotting the set of points from {1,1} to {10,10} ?
For[i = 1, i <= 10, i++, Graphics[Point[{i, i}]]]

Graphics[Table[Point[{i, i}], {i, 10}]]
If you want to see the output of your command, modify it a little:
For[i = 1, i <= 10, i++, Print@Framed@Graphics[Point[{i, i}]]]
You will see ten graphics, one point in each one

$\begingroup$ also
Graphics[Point@Table[{i, i}, {i, 10}]]$\endgroup$– rm -rf ♦Commented Sep 11, 2012 at 21:41 -
$\begingroup$ what I am actually interested in is generating
irandom points (Forseems like a good idea when a number of loop repetitions is known) and then plotting them. Could you give me a hint about this? $\endgroup$– alexCommented Sep 11, 2012 at 21:45 -
$\begingroup$ @alex Put the loop (in
Tableform) inside theGraphics$\endgroup$ Commented Sep 11, 2012 at 21:46 -
1$\begingroup$ @alex So something like:
Graphics[Point@RandomReal[1, {100, 2}]]? $\endgroup$– rm -rf ♦Commented Sep 11, 2012 at 21:47 -
$\begingroup$ I managed to make it work with something like:
ListPlot[Table[{RandomReal[{startRange, endRange}], RandomReal[{min, max}]}, {pointsCount}]]. Thanks $\endgroup$– alexCommented Sep 11, 2012 at 22:17
