Usage

The sample code below creates two charts, one vertical and one horizontal with 4 values randomly generated

// Create a horizontal chart

SBBarChart *horizontal = [[SBBarChart alloc] initWithFrame:CGRectMake(10, 20, 300, 40)]; [horizontal setHorizontal:YES]; [self.view addSubview:horizontal];

SBBarChart *vertical = [[SBBarChart alloc] initWithFrame:CGRectMake(10, 80, 50, 320)]; [vertical setHorizontal:NO]; [self.view addSubview:vertical];

// Create 4 segments for chart NSMutableArray *segments = [[NSMutableArray alloc] initWithCapacity:4];

for (int i = 0; i <= 4; i++) {

// Value randomly generated for demo

SBBarSegment *segment = [SBBarSegment barComponentWithValue:(arc4random() % 10) + 1];

switch (i) {
case 0:
segment.color = UIColorFromRGB(0x202B30); // Segment color break;
case 1:
segment.color = UIColorFromRGB(0x4E7178); break;
case 2:
segment.color = UIColorFromRGB(0x4FA9B8); break;
case 3:
segment.color = UIColorFromRGB(0x74C0CF); break;
case 4:
segment.color = UIColorFromRGB(0xF1F7E2); break;
default:
segment.color = UIColorFromRGB(0xF1F7E2); break;

}

[segments addObject:segment];

}

[horizontal setSegments:segments]; // Set segments for horizontal chart [vertical setSegments:segments]; // Set segments for vertical chart [segments release];

[horizontal release]; [vertical release];
