如何在MPAndroidChart中连续更新Y轴值 [英] How to continuously update Y-axis values in MPAndroidChart

问题描述

我希望LineChart中的轴实时调整其最大值和最小值.当新数据的Y值增加(正值和负值)时，如resetAxisMaxValue()和resetAxisMinValue()之类的功能可以很好地工作，但是，一旦信号再次变低，Y值的最大值和最小值就永远不会下降到较小的值，因此它可以显示图整个画布上的所有新数据.我想检查是否有自动执行此操作的方法，或者是否应该使用蛮力.谢谢.

I want my axis in LineChart to adjust it's maximum and minimum values real-time. Functions like resetAxisMaxValue() and resetAxisMinValue() work well when new data's Y-value is increasing(both positive and negative), however, once the signal gets low again Y-value max and min never drops to the smaller values so it can show all new data on the full canvas of the graph. I wanted to check whether there is method to do so automatically, or whether I should use brute force. Thank you.

MPAndroidChart有一个名为 setAutoScaleMinMaxEnabled(boolean enabled)的方法.它使您的图表可以自动调整图表的比例.您可以像这样简单地使用它.

MPAndroidChart has a method called setAutoScaleMinMaxEnabled(boolean enabled). It enables your chart to automatically adjusts the chart's scale. You could use it simply like this.

chart.setAutoScaleMinMaxEnabled(true);
