## Introduction
  
 * UUChart
 * UULineChart
 * UUBarChart
 * UUColor
 * UUBar
 
## Usage

### init

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

#### Select from two styles for UUChartView:

    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;

####Additional options available for UUChartLineStyle

    //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;

#### UUChart, based on kevinzhow's [PNChart](https://github.com/kevinzhow/PNChart), was created on 2014-7-24, although UUChart is now very different from PNChart.


### Demo

    chartView = [[UUChart alloc]initwithUUChartDataFrame:CGRectMake(10, 10, [UIScreen mainScreen].bounds.size.width-20, 150)
                                              withSource:self
                                               withStyle:indexPath.section==1?UUChartBarStyle:UUChartLineStyle];
    [chartView showInView:self.contentView];

//Horizontal Axis Label

    - (NSArray *)UUChart_xLableArray:(UUChart *)chart
    {
	    if (path.section==0) {
	        switch (path.row) {
	            case 0:
	                return [self getXTitles:5];

//Creating multiple array values (note the datatype)

	    if (path.section==0) {
	        switch (path.row) {

	        }else{
	            return @[ary4];
	        }
	    }
    }

//Array of colors

    - (NSArray *)UUChart_ColorArray:(UUChart *)chart
    {
        return @[UUGreen,UURed,UUBrown];
    }

//Choose line chart range

    - (CGRange)UUChartChooseRangeInLineChart:(UUChart *)chart
    {
	    if (path.section==0 && (path.row==0|path.row==1)) {
	        return CGRangeMake(60, 10);
	    }

	        return CGRangeMake(100, 0);
	    }
	    return CGRangeZero;

#### Features only available for line charts

   //Ability to declare line chart range

    - (CGRange)UUChartMarkRangeInLineChart:(UUChart *)chart
    {
       if (path.row==2) {
           return CGRangeMake(25, 75);
        }
      return CGRangeZero;
    }

  //Display horizontal line

    - (BOOL)UUChart:(UUChart *)chart ShowHorizonLineAtIndex:(NSInteger)index
    {
        return YES;
    }

  //Determine the minimum and maximum display

    - (BOOL)UUChart:(UUChart *)chart ShowMaxMinAtIndex:(NSInteger)index
    {
        return path.row==2;
    }
