So do not add the null value to the array.

[RahulM1987]

it considers the blank string value as 0 and plots the points as from 0.
I don't want to plot the 0 value points from start
The starting point should not be 0 value
How do i set that....

[danielgindi]

@RahulM1987 Do not insert a value for that index

[RahulM1987]

Great work bro nice library with zoom in and zoom out working great on both the platforms iOS and Android
Cheers
Thank you :)

@danielgindi

May I ask how not to insert value for that index? I want to skip some of the xIndex.

I'm using this method, but it's a double, not pointer.

@interface ChartDataEntry : NSObject
- (nonnull instancetype)initWithValue:(double)value xIndex:(NSInteger)xIndex OBJC_DESIGNATED_INITIALIZER;
@end

There is no method called initWithXIndex:(NSInteger)xIndex.
