UUChartView

Line and Bar of Chart, you can mark the range of value you want, and show the max or min values in linechart

Introduce

• UUChart
• UULineChart
• UUBarChart
• UUColor
• UUBar

Usage

init

-(id)initwithUUChartDataFrame:(CGRect)rect 
                   withSource:(id<UUChartDataSource>)dataSource 
                    withStyle:(UUChartStyle)style;

UUChartView have two style to select:

UUChartLineStyle,
UUChartBarStyle

UUChartDataSource

####required

- (NSArray *)UUChart_xLableArray:(UUChart *)chart;
//The target array's object's class is equal to NSArray
- (NSArray *)UUChart_yValueArray:(UUChart *)chart;

####optional

// the colors for lines and bars.
- (NSArray *)UUChart_ColorArray:(UUChart *)chart;
//CGRange CGRangeMake(CGFloat max, CGFloat min);
- (CGRange)UUChartChooseRangeInLineChart:(UUChart *)chart;

####Only apply in lineChart

//Mark the range of values with grayColor if you need
- (CGRange)UUChartMarkRangeInLineChart:(UUChart *)chart;

//You can choose horizonLine which you want to show
- (BOOL)UUChart:(UUChart *)chart ShowHorizonLineAtIndex:(NSInteger)index;

// Show the label on the max and min values with their colors.
- (BOOL)UUChart:(UUChart *)chart ShowMaxMinAtIndex:(NSInteger)index;
