Problem with Bar Height

[meduza]

I followed the tutorial and had a problem with bar height. Every time one bar has zero height (not showing in a view).

This is my code:

• (void)viewDidLoad
  {
  [super viewDidLoad];
  // data array
  _data = @[@20, @30, @50];

  JBBarChartView *barChartView = [[JBBarChartView alloc] init];
  barChartView.delegate = self;
  barChartView.dataSource = self;
  barChartView.frame = CGRectMake(20, 120, 280, 200);
  barChartView.autoresizingMask = UIViewAutoresizingFlexibleWidth;
  barChartView.layer.borderWidth = 1;
  [self.view addSubview:barChartView];

  [barChartView reloadData];
  }

• (NSUInteger)numberOfBarsInBarChartView:(JBBarChartView *)barChartView{
  NSLog(@"numberOfBarsInBarChartView: %lu", (unsigned long)[self.data count]);
  return [self.data count];
  }

• (CGFloat)barChartView:(JBBarChartView *)barChartView heightForBarViewAtAtIndex:(NSUInteger)index{
  NSLog(@"heightForBarViewAtAtIndex: %lu, height: %f", index, [[self.data objectAtIndex:index] floatValue]);
  return [[self.data objectAtIndex:index] floatValue];
  }

Debug log:

12:51:55.054 App[5116:60b] numberOfBarsInBarChartView: 3
12:51:55.055 App[5116:60b] heightForBarViewAtAtIndex: 0, height: 20.000000
12:51:55.056 App[5116:60b] heightForBarViewAtAtIndex: 1, height: 30.000000
12:51:55.057 App[5116:60b] heightForBarViewAtAtIndex: 2, height: 50.000000

Try setting the barChartView.minimumValue = 0.0f;

By default, the minimum value of a chart is set to the minimum value of the datasource's collection.

Got it! Thank you!
