Hi, I have the code in which i want to develop the graph.The code is,
NSArray *coordinate = [[NSArray alloc] initWithObjects: @"42,213", @"75,173", @"108,153", @"141,133", @"174,113", @"207,73", @"240,33", nil];
CGContextSetRGBFillColor(ctx, 255, 0, 0, 1.0);
CGContextSetLineWidth(ctx, 8.0);
for(int intIndex = 0; intIndex < [coordinate count]; fltX1+=33, intIndex++)
{
CGContextMoveToPoint(ctx, fltX1+37, fltY2+18);
CGPoint point = [[coordinate objectAtIndex:intIndex] CGPointValue];
CGContextAddLineToPoint(ctx, point);
CGContextStrokePath(ctx);
}
The problem is that the function of CGContextAddLineToPoint(ctx, point); not working properly. How i drawing the line in the graph using above code????????
