CGPoint value of given data points
posted

Hi all...

I want to use custom labels. I will implement my own labels. But i have to know point values of my data array. For example my line series data source;

        categorySource = [[IGCategorySeriesDataSourceHelper alloc] init];

        categorySource.values = dataArray;

        categorySource.labels=labelArray;

        

After chart drawn i want to get CGPoint value of specific data array rows. For example i need the x coordinate of fifth element of my array. So i can put my custom label at that x coordinate under x axis.

    Hi,

    The chart view allows you to specify custom labels at render time by using -labelForAxis delegate method. The chart view doesn't exactly deal in CGPoints when it comes to labels. It's more like it tells you what the current label is for a given data point and gives you an option to change it to another string.

    I'm attaching a sample that places a custom label at index 5.
