AAChartModel
每5秒刷新AAChartModel時無法加載圖表
### 當我在嘗試用infinite while loop 做出實時刷新的圖表時，圖表無法加載，跪求大大們的協助， 以下是我的code：
-
(void)viewDidLoad { [super viewDidLoad]; // NSTimeInterval time=[date timeIntervalSince1970];// *1000 是精确到毫秒，不乘就是精确到秒 // NSString *timeString = [NSString stringWithFormat:@"%.0f", time];
[self initDate]; //self.view.frame.size.height - 250; CGFloat chartViewWidth = self.view.frame.size.width; CGFloat chartViewHeight = self.view.frame.size.height; _aaChartView = [[AAChartView alloc]init]; // _aaChartView.frame = CGRectMake(0, 60, chartViewWidth, chartViewHeight); _aaChartView.frame = CGRectMake(50, 200, chartViewWidth-100, chartViewHeight-250); _aaChartView.scrollEnabled = NO; [self.view addSubview:_aaChartView];
AAChartModel *aaChartModel = AAChartModel.new .chartTypeSet(AAChartTypeArea) .titleSet(@"THE HEAT OF PROGRAMMING LANGUAGE") .subtitleSet(@"Virtual Data") .categoriesSet(@[self.na4,self.na3,self.na2,self.na1, self.na]) .yAxisTitleSet(@"Degrees Celsius") .seriesSet(@[
AASeriesElement.new .nameSet(@"2017") // .dataSet(array), .dataSet(@[@7.0, @6.9, @9.5, @14.5, @18.2]), ]);[_aaChartView aa_drawChartWithChartModel:aaChartModel];
// NSNumber *I = [NSNumber numberWithFloat:i];
[self updateValue]; [self initButton];
} -(void)updateValue{ ／／ update values every 5 seconds
while(true){
float rndValue1 = (((float)arc4random()/0x100000000)*47);
float rndValue2 = (((float)arc4random()/0x100000000)*47);
float rndValue3 = (((float)arc4random()/0x100000000)*47);
float rndValue4 = (((float)arc4random()/0x100000000)*47);
float rndValue5 = (((float)arc4random()/0x100000000)*47);
NSNumber *value6 = [NSNumber numberWithFloat:rndValue1];
NSNumber *value7 = [NSNumber numberWithFloat:rndValue2];
NSNumber *value8 = [NSNumber numberWithFloat:rndValue3];
NSNumber *value9 = [NSNumber numberWithFloat:rndValue4];
NSNumber *value10 = [NSNumber numberWithFloat:rndValue5];
NSMutableArray *newArray = [[NSMutableArray alloc]initWithObjects: value6 ,value7,value8, value9,value10, nil];
AAChartModel *aaChartModel2 = AAChartModel.new
.chartTypeSet(AAChartTypeArea)
.titleSet(@"THE HEAT OF PROGRAMMING LANGUAGE")
.subtitleSet(@"Virtual Data")
.categoriesSet(@[@"1",@"2",@"3",@"4", @"5",@"6",@"7",@"C#",@"C++"])
.yAxisTitleSet(@"Degrees Celsius")
.seriesSet(@[
AASeriesElement.new
.nameSet(@"2018")
// .dataSet(array),
.dataSet(newArray),
]);
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{ [self->_aaChartView aa_refreshChartWithChartModel:aaChartModel2];});
// [self increment];
} }
以下是我的 console log： 2020-12-26 15:27:22.832082+0800 data_test[38663:1161019] ----------- console log AAOptions JSON information of AAChartView -----------: { "credits" : { "enabled" : false }, "subtitle" : { "align" : "left", "text" : "Virtual Data", "style" : {
