我试图做出与此类似IOS-图表合并图表：酒吧去图表
我要去有4个BarChartDataSets分组东西过去右轴，和2个LineChartDataSets，每个数据集有7个数据点，用户可以添加或随意取出这些数据集
杆似乎分组细，线图表显示了所有7个点
但作为添加更多BarChartDataSets到图表，该酒吧去吧在图表的右侧，折线图保持不变，这里是我以一个LineChartDataSet开始的图像序列，然后逐个添加BarChartDataSets，其中一些小节的值为0，因此很难看清楚该组中，查找0标签底部
如何才能停止从去关闭图表右边的酒吧？
下面是代码：
//get data and values from DataMOs in the activeFeeds
var lineChartDataSets = [LineChartDataSet]()
var barChartDataSets = [BarChartDataSet]()
for (key, dayValuesArray) in valuesByFeed {
var barChartDataEntries = [BarChartDataEntry]()
var lineChartDataEntries = [ChartDataEntry]()
var lineChartDataSet: LineChartDataSet!
var barChartDataSet: BarChartDataSet!
var dataEntry: ChartDataEntry
for (index, value) in (dayValuesArray?.enumerated())! {
//create line chart for Demand and Prod feeds
//create bar chart for every other feed
if key == "Demand" || key == "Prod"{
dataEntry = ChartDataEntry(x: Double(self.activeFeeds.count * index), y: Double(value)!)
lineChartDataEntries.append(dataEntry)
} else {
dataEntry = BarChartDataEntry(x: Double(self.activeFeeds.count * index), y: Double(value)!)
barChartDataEntries.append(dataEntry as! BarChartDataEntry)
}
}
//create line chart data set for Demand and Prod feeds
//create bar chart data set for every other feed
if key == "Demand" || key == "Prod"{
lineChartDataSet = LineChartDataSet(values: lineChartDataEntries, label: key)
lineChartDataSet.drawCirclesEnabled = false
} else {
barChartDataSet = BarChartDataSet(values: barChartDataEntries, label: key)
}
switch key {
case "Solar":
barChartDataSet.setColors(UIColor.orange.withAlphaComponent(1.0))
barChartDataSet.valueTextColor = UIColor.white
break
case "Wind":
barChartDataSet.setColors(UIColor.blue.withAlphaComponent(1.0))
barChartDataSet.valueTextColor = UIColor.white
break
case "Battery":
barChartDataSet.setColors(UIColor.green.withAlphaComponent(1.0))
barChartDataSet.valueTextColor = UIColor.white
break
case "Gen":
barChartDataSet.setColors(UIColor.red.withAlphaComponent(1.0))
barChartDataSet.valueTextColor = UIColor.white
break
case "Demand":
lineChartDataSet.setColors(UIColor.purple.withAlphaComponent(1.0))
lineChartDataSet.valueTextColor = UIColor.white
lineChartDataSet.drawFilledEnabled = true
lineChartDataSet.fillColor = UIColor.purple.withAlphaComponent(0.8)
break
case "Prod":
lineChartDataSet.setColors(UIColor.magenta.withAlphaComponent(1.0))
lineChartDataSet.valueTextColor = UIColor.white
lineChartDataSet.drawFilledEnabled = true
lineChartDataSet.fillColor = UIColor.magenta.withAlphaComponent(0.8)
break
default:
break
}
//append to correct data set array
if key == "Demand" || key == "Prod"{
lineChartDataSets.append(lineChartDataSet)
} else {
barChartDataSets.append(barChartDataSet)
}
}
//set chart data
let chartData = CombinedChartData()
chartData.barData = BarChartData(dataSets: barChartDataSets)
chartData.lineData = LineChartData(dataSets: lineChartDataSets)
let activeFeedsCount = self.activeFeeds.count
if activeFeedsCount > 0 {
self.combinedChartView.data = chartData
if chartData.barData.dataSetCount > 1 {
self.combinedChartView.barData?.groupBars(fromX: 0, groupSpace: 1.0, barSpace: 0.5)
self.combinedChartView.notifyDataSetChanged()
}
} else {
self.combinedChartView.data = CombinedChartData()
self.combinedChartView.noDataText = "No Feeds To Show"
}
使用setVisibleXRange可以解决这个问题，看我的这个答案：https://stackoverflow.com/a/44852890/5881884如果不解决这个问题，可以大家分享一些代码所以我可以重现这个问题？ – DevB2F
似乎没有工作，我添加了即时通讯代码，它的基本数据点为过去7天，将有7组4条，2条折线图，每个数据点有7个数据点 –
然后我建议更改粒度：https：//stackoverflow.com/a/44856224/5881884 – DevB2F
