I also need this feature, how to achieve it?

Hi, I have found the solution. There is a function called "setVisibleXRangeMaximum". It means that you can set the 6 months data that will display in the chartView, and you can scroll the chart to see other 6 months data.
Hope it can help you!

@weifengsmile I have set the property, but it still doesn't work for me... I have set the maxVisibleCount and setVisibleXRangeMaximum. Plus, the dataArray's count is greater than the both. So I have no idea how to scroll the Chart without a ScrollView

[dandanbrother]

Oh, I just set the property after the chart's data has been set then it can be scrolled.

use setVisibleXRange or similar proerties like moveViewToX

@liuxuan30 when i use HorizontalBarChartView, i also need display partial data, scroll to display other data. But i set setVisibleXRangeMaximum or setVisibleXRangeWithMinXRange:<#(double)#> maxXRange:<#(double)#> still doesn't work. can you help me how to solve it? thank.

我这边需求 一共可能30条数据，然后默认只显示五条，其余的通过左滑
已经进行了如下设置
[_lineView setVisibleXRangeMaximum:10];// 最大显示
[_lineView setVisibleXRangeMinimum:4];// 最小显示
[_lineView moveViewToX:19];// 移动到那个点 x轴坐标
现在不能进行拖拽，不知道如何解决
lineChartView.dragEnabled = YES;//启用拖拽图标
这个也已经设了，请问下如何解决呢？
