如何使我的Horizo​​ntalBarChart可滚动? [英] How can I make my HorizontalBarChart scrollable?

问题描述

当前尝试使用MPAndroidChart实现Horizo​​ntalBarChart.但是，条形太多，无法完全显示在屏幕上.仅当我放大时，Horizo​​ntalBarChart才会滚动，但永远不会超过屏幕上已经显示的内容.不知道这是一个XML问题(我在相对布局中有Horizo​​ntalBarChart，尝试过ScrollView但没有用)还是已经有一个诸如chart.enableScroll()的实现(我已经尝试过了，但不起作用) ).

Currently trying to implement a HorizontalBarChart using MPAndroidChart. However, there are too many bars and they won't all fit on the screen. HorizontalBarChart will scroll only if I zoom in, but will never go past what was already on the screen. Not sure if this is an XML problem (I have the HorizontalBarChart in a Relative Layout, tried ScrollView but didn't work) or if there's already an implementation like chart.enableScroll() (which I have tried, and it doesn't work).

推荐答案

您可以使用chart.setVisibleXRangeMaximum(10)来控制应该一次可见的条目数.如果图表包含更多值，它将自动允许滚动.

You can use chart.setVisibleXRangeMaximum(10) to control the number of entries that should be visible at once. If the chart contains more values, it will automatically allow scrolling.
