I have created a CombinedChartView with lineDataSets and CandleDataSets. The CandleDataSets are used to highlight certain data points.
This has all worked fine except for the Legend. When I enable the legend it only shows legend information for the LineDataSets.
I looked into the LegendRenderer and discovered the problem arises here ->
@objc open func computeLegend(data: ChartData)
{
guard let legend = legend else { return }
if !legend.isLegendCustom
{
var entries: [LegendEntry] = []
// loop for building up the colors and labels used in the legend
for i in 0..<data.dataSetCount
...
The dataSetCount only counts lineDataSets and ignores the candleDataSet. So any data sets after the line data are ignored.
My setup looks like this;
self.chartView.data = CombinedChartData()
if let chartView = self.chartView
{
let allData = CombinedChartData()
allData.lineData = LineChartData()
for line in lineData.values
{
if line.isVisible
{
allData.lineData.addDataSet(line)
}
}
allData.candleData = CandleChartData()
for fiducialMark in buttonData.values
{
if fiducialMark.isVisible
{
allData.candleData.addDataSet(fiducialMark)
}
}
chartView.data = allData
chartView.chartDescription?.text = self.fileLabel.stringValue
chartView.needsDisplay = true
chartView.rightAxis.enabled = false
chartView.legend.enabled = true
}
