Hi,

I’m trying to convert Java code to swift and I need the AnnotationLabel’s setAxisLabelStyle equivalent.

AnnotationLabel annotationLabel = new AnnotationLabel(getContext());
annotationLabel.setLabelPlacement(LabelPlacement.Axis);

            annotationLabel.setAxisLabelStyle(new Action1<AnnotationLabel>()
            {
                @Override
                public void execute(AnnotationLabel annotationLabel)
                {
                    annotationLabel.setFontStyle(new FontStyle(37.0f, Color.BLUE));
                    annotationLabel.setBackgroundResource(R.drawable.current_price);
                }
            });

How can i apply this code in swift?

How would I go about doing this in swift?

I would like to add scrollBar to SCINumericAxis for example xAxis.

I did find documentation:
https://www.scichart.com/documentation/v5.x/webframe.html#Scrollbars.html

But on iOS version, I can’t find numericAxis.Scrollbar is missing

Hello,
I’m trying to convert Android (Java) code to iOS (Swift), and I need to create a custom SCIZoomPanModifier. In the android code, onFling, onDown, and onDown were overridden, but I can’t seem to do that in iOS. How can I override onFling, onDown, and onUp in iOS to mimic the android code?

Thanks

SplineLineRenderableSeries doesn’t render curved graph line properly in Swift , it renders stepped line for the data series .For reference please check the Screenshot attached ,ECG line(Green) rendered as stepped line (Marked by rectangle). Let me know anything I need to update in my code

Please find below the code for initialisation go the graph and updating the graph same. I am updating graph realtime with same DataSeries.

1. Graph initialisation code

   func init_ECG_Chart()
   {
   //Remove Theme From Chart By Apply & Remove & Change Border color
   SCIThemeManager.applyTheme(to: self.ecg_Chart_Surface, withThemeKey: SCIChart_Bright_SparkStyleKey)
   SCIThemeManager.removeTheme(byThemeKey: SCIChart_Bright_SparkStyleKey)

   self.ecg_Chart_Surface.isOpaque = false
   self.ecg_Chart_Surface.backgroundColor = .clear
   self.ecg_Chart_Surface.renderableSeriesAreaBorderStyle = SCISolidPenStyle(color: .clear, thickness: 0)
   
   //Line
   let lineSeries = SCISplineLineRenderableSeries()
   
   lineSeries.strokeStyle = SCISolidPenStyle(color: ecgSelectedColor, thickness: 2.0)
   lineSeries.dataSeries = ecgLineDataSeries
   

   // lineSeries.resamplingMode = SCIResamplingMode_None //Resampling off
   // lineSeries.resamplingMode = SCIResamplingMode_Auto //Resampling off

   let xAxis = SCINumericAxis()
   xAxis.axisAlignment = .bottom
   xAxis.drawLabels = false
   xAxis.drawMajorGridLines = false
   xAxis.drawMinorGridLines = false
   xAxis.drawMajorTicks = false
   xAxis.drawMinorTicks = false
   
   let yAxis = SCINumericAxis()
   yAxis.axisAlignment = .left
   yAxis.drawLabels = false
   yAxis.drawMajorGridLines = false
   yAxis.drawMinorGridLines = false
   yAxis.drawMajorTicks = false
   yAxis.drawMinorTicks = false
   yAxis.autoRange = .never   //Stop auto ranging axis
   yAxis.visibleRange = SCIDoubleRange(min: -32, max: 96)
   

   // yAxis.visibleRangeLimit = SCIDoubleRange(min: -32, max: 96)

   yAxis.growBy = SCIDoubleRange(min: 0.2, max: 0.2)
   
   SCIUpdateSuspender.usingWith(self.ecg_Chart_Surface) {
   
       self.ecg_Chart_Surface.xAxes.add(items: xAxis)
       self.ecg_Chart_Surface.yAxes.add(items: yAxis)
       self.ecg_Chart_Surface.renderableSeries.add(items: lineSeries)
   
       //self.ecg_Chart_Surface.chartModifiers.add(items: SCIZoomExtentsModifier(),SCIPinchZoomModifier())
   }
   

   } //Init ECG

2. Graph updation code

   func update_ECG_Chart(xValues:SCIDoubleValues,yValues:SCIDoubleValues)
   {

   SCIUpdateSuspender.usingWith(self.ecg_Chart_Surface) {
   
       self.ecgLineDataSeries.append(x: xValues, y: yValues)
     //  self.ecg_Chart_Surface.zoomExtents()
   
       self.ecg_Chart_Surface.zoomExtentsX()
   
   }
   

   } //Update ECG
