crs12decoder Posted March 10, 2011 Report Share Posted March 10, 2011 http://crs12decoder.comoj.com/interfata.phpPentru nevoi personale am facut un script php de generat grafice dupa puncte de coordonate.Preview: http://crs12decoder.comoj.com/grafic.phpPoate mai are cineva nevoie de asa ceva asa ca-l postez aici:<?php$puncte = array(1 => '0,0',2 => '3,2',3 => '5,7',4 => '8,4');$linii = 10;$coloane = 20;header ("Content-type: image/jpeg");$height = 250;$width = 600;$img = imagecreate ($width,$height);$fond = imagecolorallocate ($img,211,211,211);$col = imagecolorallocate ($img,0,0,0);$linecol = imagecolorallocate ($img,82,10,26);$textcol = imagecolorallocate ($img,0,34,102);imageline ($img,0,$width,0,0,$col);imageline ($img,$width,0,0,0,$col);imageline ($img,0,$height-1,$width,$height-1,$col);imageline ($img,$width-1,0,$width-1,$height,$col);//forsyn$ay=0;for($i=0; $i<=$linii; $i++){$ay=$ay+$height/$linii;imageline ($img,0,$ay,$width,$ay,$col);}//forsyn//forsxn$ay=0;for($i=0; $i<=$coloane; $i++){$ay=$ay+$width/$coloane;imageline ($img,$ay,0,$ay,$height,$col);}//forsxnfor($i=1; $i<=count($puncte); $i++){$exp = explode(',', $puncte[$i]);$x[$i] = $exp[0];$y[$i] = $exp[1];}for($i=1; $i<=count($x); $i++){$ax[$i] = $x[$i]*$width/$coloane;$bx[$i] = $y[$i]*$height/$linii;$bx[$i] = $height-$bx[$i];imagestring ($img,5,$ax[$i],$bx[$i]+1,'('.$x[$i].';'.$y[$i].')',$textcol);}for($i=1; $i<count($bx); $i++){imageline ($img,$ax[$i],$bx[$i],$ax[$i+1],$bx[$i+1],$linecol);}imagejpeg ($img, '', 100);?>Utilizare:1) In array-ul $puncte, exact la inceput sunt date punctele de coordonate x si y. De acolo puteti adauga,sterge,modifica puncte/coordonate.2) Grid-urile verticale si orizontale sunt intre //forsxn sau //forsyn pentru cei care nu vor sa le vada.3) Inaltimea si latimea 100% modificabile fara sa denatureze valorile graficului.4) $linii, $coloane = numarul de linii si de coloane care sa delimiteze graficul (schimbati valorile si veti intelege)5) ImageString ($img,5,$ax[$i],$bx[$i]+1,'('.$x[$i].';'.$y[$i].')',$textcol); este linia care face sa apara pe grafic valorile numerice.. in caz ca vreti sau nu sa va apara, o stergeti.

Birkoff Posted March 10, 2011 Report Share Posted March 10, 2011 Fatal error: Call to undefined function ImageCreate() on line 15ca idee, functiile interne php se scriu cu litere mici... editeaza scriptul si corecteaza, nu toata lumea de aici stie cum sa corecteze...
