问题 I am using MPAndroidChart library for my project. Is it possible to rotate the labels of the XAxis by 270 degrees so that I can fit more text? 回答1: Original answer: Unfortunately it is currently not possible to rotate the values on the x-axis of a chart to a certain degree / angle. You will have to implement such a feature yourself. UPDATE: As of v2.1.5 this feature is now available: XAxis xAxis = chart.getXAxis(); xAxis.setLabelRotationAngle(...); 回答2: do it simply by XAxis xAxis=barChart
