Bar图内容超出坐标轴范围

[ToughRover]

使用echarts绘制stacked bar出现bar内容超出坐标轴的情况，如下图所示

Version & Environment [版本及环境]

• ECharts version [ECharts 版本]: 4.1.0
• Browser version [浏览器类型和版本]: Chrome 69.0.3497.100 (Official Build) (64-bit)
• OS Version [操作系统类型和版本]: macOS Majove 10.14

Expected behaviour [期望结果]

bar图内容不应该超出坐标轴的最大值范围，因为坐标轴并未显式设置最大和最小值，是echarts 自动适配的

ECharts option [ECharts配置项]
