Can't show long label at XAxis in BarChart

[panicake]

When the label is too long to show the label at one line, the label is dispeared, and I puzzled! I finally find the problem, in BarChart's function drawXAxis, there is calling of function Draw.TextWithin, this function has a bug；

in draw.go line 23 lines := Text.WrapFit(r, text, box.Width(), style) lines array will contains empty string, like ["", "test"], empty string will cause lineBox := r.MeasureText(line), lineBox.Width() and lineBox.Height() get invalid value.

I fixed this by rewriting the code in text.go WrapFitWord function, line 101

// old

	output = append(output, t.Trim(line))
			

// new
if len(line) != 0 {
	output = append(output, t.Trim(line))
}

当BarChat的横坐标的标签过长时，会导致标签不显示。 原因是 在BarChart调用drawXAxis，Draw.TextWithin, 在一个框里画标签时，首先会将标签分成多行lines := Text.WrapFit(r, text, box.Width(), style)，然而分成多行后，lines数组里总是有空字符串，空字符串会导致在计算box时无法获取box的高和宽，导致文字的坐标偏离十万八千里。 我通过改源码修复，在in text.go WrapFitWord function, 101行：

// old

	output = append(output, t.Trim(line))

// new
if len(line) != 0 {
	output = append(output, t.Trim(line))
}

Any update on this?
