How to Shows the Datapoint values in CustomAnimation-line chart?

[Nandu]

Hi,

 Im using TKChart, i have done the line graph X-axis ​dates and y-axis integer values. But how i can show the graph data point values?

Im using below method.

- (void)chart:(TKChart *)chart didSelectPoint:(id<TKChartData>)point inSeries:(TKChartSeries *)series atIndex:(NSInteger)index
{
    NSLog(@"A point tapped!");
    UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"" message:[NSString stringWithFormat:@"%@",[serverData objectAtIndex:index]] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles: nil];
    [alert show];
}

above method im showing 1 alert, but i don't want to alert. I want to shows the data points in label or any other way.

Thanks.

Hello Nandu,

To show the values of your data points you should make the point labels of the series visible.

columnSeries.style.pointLabelStyle.textHidden = NO;
columnSeries.style.pointLabelStyle.labelOffset = UIOffsetMake(0, -15);

There is an article, in our online documentation, dedicated to the point labels and their usage.

In case you want to have a custom appearance of the point labels you should conform to the TKChartDelegate and provide custom labels as you implement the chart:labelForDataPoint:inSeries:atIndex: method.
You can find examples of point labels customization in our  point labels customization article.

In case you have other or further questions, feel free to write us back any time.
