Setting circleHoleColor to clear causes artifact

[nicholassmith]

If you set the circle hole colour to be [UIColor clearColor] then the circle is drawn with an artifact as shown.

can you provide full color data?

[nicholassmith]

Sure:

    [self.highlightedSet setHighlightColor:[UIColor clearColor]];
    self.highlightedSet.drawValuesEnabled = NO;
    self.highlightedSet.drawCirclesEnabled = YES;
    self.highlightedSet.circleHoleColor = [UIColor clearColor];
    self.highlightedSet.circleColors = [NSArray arrayWithObject:[UIColor whiteColor]];
    self.highlightedSet.circleHoleRadius = 7.5f;
    self.highlightedSet.circleRadius = 8.0f;
    self.highlightedSet.colors = [NSArray arrayWithObject:[UIColor whiteColor]];

There's another data set below it which is drawn with a plain white dot.

I was able to reproduce in ChartsDemo with your code.

I'm trying to avoid updating to a fresh version this week, can I just apply that change to my local copy of the Swift files?

you can take my code if you can edit the code in your project. Or use subclass to apply it. and wait for this get merged
