[BUG] xAxis label too long causes radar chart cannot render correctly

[liuxuan30]

By accident I see my data source feed a very long string, about 4xx width, and this causes the radar chart cannot draw itself.

I have managed to limit the width through hard code (not finding a good place to hold the variable):

        _xAxis.labelWidth = widthText.sizeWithAttributes([NSFontAttributeName: _xAxis.labelFont]).width;

        if (_xAxis.labelWidth > 100)
        {
            _xAxis.labelWidth = 100
        }

        _xAxis.labelHeight = _xAxis.labelFont.lineHeight;
        _xAxis.values = xValues;

However, this limit the size, but when rendering, it still draw the whole text. Is there any way to render the text only within the rect? Tried to find a API, but no good.

This is the chart after I have set the width up to 100:

I'm seeing this too - Basically if you have a label that's longer than a certain number of characters (haven't tested exactly, but it's <20 so not that long) the chart becomes tiny.

Yes, this is a defect because it need take the radius and label width into account while calculating. The idea is to show all the labels and chart. I am suggesting add a limit for the label width, and once it exceeds, it will render the text like "ABCD..."

I am having trouble to implement this, becuase the drawText function don't cut the rect

This, too, is a duplicate of #153. Please merge the discussions :-)

I'm just trying to track the bugs and it makes it harder to try to understand the same bug twice...
