How can I combine two lineCharts？

[Args]

What did you do?

I try to use CombinedChartView,but it doesn't seem to combine two charts of the same type

What did you expect to happen?

I want to combined two lineCharts,and can update data together.Code like this

    CombinedChartData *data = [[CombinedChartData alloc] init];
    data.lineData0 = [self generateLineData0];
    data.lineData1 = [self generateLineData1];

or

    CombinedChartData *data = [[CombinedChartData alloc] init];
    data.lineDataArr = [self generateLineDataArr];

What happened instead?

    CombinedChartData *data = [[CombinedChartData alloc] init];
    data.lineData = [self generateLineData];

Use the demo app for examples. What you're looking for is in LineChart2. You can initialize LineChartData with multiple LineChartDataSets:

let data = LineChartData(dataSets: [set1, set2, set3])
chartView.data = data

where chartView is a an instance if LineChartView

Just use two line chart data sets. There are examples in multiple line chart

Hi @liuxuan30
How to do the same with along with bar chart?
I want to set 2 line data set and 1 bar data set.
And overlapping would be like this "Line 1 , Bar 1, Line 2"
