MP Android图表从右向左滚动数据 [英] Mp Android Chart Scrolling the data from right to left

问题描述

我正在使用MpAndroid图表库构建条形图，我大约有50-60条，想要显示最初的60条，即显示ArrayList中的最后一个元素，滚动方向应该是从右到左.

I'm Building a barchart using MpAndroid chart library, i've around 50 - 60 bars and wanted to display the 60th initially i.e. display the last element in the ArrayList and the scroll should be from right to Left.

主要目的是在图表条形图的初始加载期间显示图表的结尾.

Main motive is to display the end of the chart during the initial load of the chart barchart.

预先感谢.

推荐答案

这对我有用.

chart.setData(...); // first set data

// now modify viewport
chart.setVisibleXRangeMaximum(20); // allow 20 values to be displayed at once on the x-axis, not more
chart.moveViewToX(10); // set the left edge of the chart to x-index 10
// moveViewToX(...) also calls invalidate()
