Below is the code used in SWIFT for apple app development to display the chart having bar chart and spline series. I couldn't understand what is not working from your explanation hence i shared the entire code for chart which is being used.
Code: Select all
let options = HIOptions()
options.exporting = HIExporting()
options.exporting.enabled = false
options.credits.enabled = false
chart.zoomType = "xy"
chart.type = "column"
chart.panning = HIPanning()
chart.panning.enabled = true
chart.panning.type = "x"
chart.pinchType = "x"
chart.events = HIEvents()
chart.events.load = HIFunction(jsFunction: "function() { var proceed = this.pointer.pinch; this.pointer.pinch = function(e) { if (e.touches.length === 1 && e.type === 'touchmove') { this.chart.pan(e, this.chart.options.panning); } else { proceed.call(this, e); if (e.type === 'touchstart') { this.chart.mouseDownX = this.pinchDown[0].chartX; this.chart.mouseDownY = this.pinchDown[0].chartY; } } } }")
