如何使我的 Horizo​​ntalBarChart 可滚动？

Question

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).

Answer 1

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.

Answer 2

chart.setData(...); // first set data
// now modify viewport
chart.setVisibleXRangeMaximum(5); // allow 5 values to be displayed
chart.moveViewToX(1);// set the left edge of the chart to x-index 1

You can use above way
