I've looked everywhere and tried various approaches and cannot figure this out. How do I position the xAxis at the bottom of the line chart?
In viewDidLoad:
[self initChartProperties];
[self updateChartData:5];
initChartProperties:
- (void)initChartProperties2 {
_chartView.delegate = self;
_chartView.descriptionText = @"";
_chartView.noDataTextDescription = @"You need to provide data for the chart.";
_chartView.dragEnabled = YES;
_chartView.pinchZoomEnabled = YES;
_chartView.legend.enabled = NO;
[_chartView setScaleEnabled:YES];
_chartView.leftAxis.customAxisMax = 21;
_chartView.leftAxis.customAxisMin = 0;
_chartView.leftAxis.drawZeroLineEnabled = NO;
_chartView.leftAxis.enabled = YES;
_chartView.xAxis.axisLineWidth = 2.0f;
_chartView.xAxis.drawAxisLineEnabled = YES;
_chartView.rightAxis.enabled = NO;
[_chartView.viewPortHandler setMaximumScaleY: 2.f];
[_chartView.viewPortHandler setMaximumScaleX: 2.f];
}
updateChartData:
- (void)updateChartData:(int)count {
NSMutableArray *xVals = [[NSMutableArray alloc] init];
NSMutableArray *yVals = [[NSMutableArray alloc] init];
for (int i = 0; i < count; i++) {
[xVals addObject:[@(i) stringValue]];
}
for (int i = 0; i < count; i++) {
[yVals addObject:[[ChartDataEntry alloc] initWithValue:i xIndex:i]];
}
LineChartDataSet *set1 = [[LineChartDataSet alloc] initWithYVals:yVals label:@""];
set1.lineWidth = 1.0;
set1.circleRadius = 0.0;
set1.drawCircleHoleEnabled = NO;
set1.valueFont = [UIFont fontWithName:@"HelveticaNeue-Light" size:9.0f];
NSMutableArray *dataSets = [[NSMutableArray alloc] init];
[dataSets addObject:set1];
LineChartData *data = [[LineChartData alloc] initWithXVals:xVals dataSets:dataSets];
_chartView.data = data;
}
Result: line graph
I just want the xAxis values to be rendered at the bottom of the graph, not the top. Sorry for the seemingly simple question. Appreciate any help.
