Change chart legend show order

[devssun]

I use Combined Chart (Line and Bar), and show legend in order LineChart label , BarChart label.
but I want to show label in order BarChart label, LineChart label.
Is there any options to order Chart label not use Legend Class? I can't find anymore...
If there any options how can I order Chart label?
Thanks for your help.

maybe ask on stack overflow.
I remember you can change the render order. Just take a look how the legend get the order.

问题还是18年提问的，现在2020年过去一半了。还是没有找到legend的排序方法。 但我朋友摸索出了一个偏方，如下：
Combined Chart (Line and Bar)中，将line的label置空。也就是隐藏line的legend. 然后 在barData中创造一个无数据的dataSet，其label设置为line的label值。这样达到偷天换日的目的。哈哈哈 。

示例：
BarChartDataSet *nullDataSet =
[[BarChartDataSet alloc] initWithEntries:@[[[BarChartDataEntry alloc] initWithX:0 y:0]] label:@"我是line"];
nullDataSet.drawValuesEnabled = NO;
nullDataSet.drawIconsEnabled = NO;
BarChartData *barData =
[[BarChartData alloc] initWithDataSets:@[barDataSet,nullDataSet]];
