code 

+ (void) drawphoto : (uiimage*) photo : (cgrect) location{     [[pdfcreator imagewithimage:[pdfcreator scaleandrotateimage:photo]     scaledtosize:cgsizemake(location.size.width, location.size.height) ] drawinrect:location]; }  + (uiimage*) scaleandrotateimage: (uiimage*) imagein {     if(imagein.size.width > imagein.size.height)     {         cgfloat rads = m_pi * 90 / 180;         float newside = max([imagein size].width, [imagein size].height);         cgsize size =  cgsizemake(newside, newside);         uigraphicsbeginimagecontext(size);         cgcontextref ctx = uigraphicsgetcurrentcontext();         cgcontexttranslatectm(ctx, newside/2, newside/2);         cgcontextrotatectm(ctx, rads);         cgcontextdrawimage(uigraphicsgetcurrentcontext(),cgrectmake(-[imagein size].width/2,-[imagein size].height/2,size.width, size.height),imagein.cgimage);         imagein = uigraphicsgetimagefromcurrentimagecontext();         uigraphicsendimagecontext();        }     return imagein; }  + (uiimage*)imagewithimage:(uiimage*)image scaledtosize:(cgsize)newsize {     uigraphicsbeginimagecontext( newsize );     [image drawinrect:cgrectmake(0,0,newsize.width,newsize.height)];     uiimage* newimage = uigraphicsgetimagefromcurrentimagecontext();     uigraphicsendimagecontext();      return newimage; }

i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
