I found a bug where the SCILegendModifier doesn’t display the full series name. If I add 5 spaces to the series name string, I’m able to see the full series name.

Also, when using margins on the legend modifier instance, the legend fills all available space. Manually resizing the window fixes this bug.

See the photos.

One thing I can’t figure out is why I don’t see the axis tooltips when using SCIRolloverModifier or SCICursorModifier? If I use xAxis.axisTitleMargins = NSEdgeInsets(top: 1000, left: 0, bottom: 10, right: 0) I can see tooltips on x axis but only until some point and from there moving the cursor to the right leads to some sort of overlay and tooltip disappears. See the photos.

Is this a bug or I’m doing something wrong?

Hello, I’m new to Swift and macOS, but I’m tasked to research SciChart. I have started my macOS trial, got my trial code from the wizard app. I’m following the Creating your first SciChart macOS App tutorial but I get Sorry! Your license token appears to be invalid error.

Here is what I’ve tried:

import Cocoa
import SciChart
import AppKit

class AppDelegate: NSObject, NSApplicationDelegate {

//    override init() {
//        SCIChartSurface.setRuntimeLicenseKey("XXX")
//    }

    func applicationDidFinishLaunching(_ aNotification: Notification) {
        let licenseKey = "XXX"

    func applicationWillTerminate(_ aNotification: Notification) {
        // Insert code here to tear down your application

    func applicationSupportsSecureRestorableState(_ app: NSApplication) -> Bool {
        return true

Using override init() leads to Terminating app due to uncaught exception 'License Exception', reason: ''
Using SCIChartSurface.setRuntimeLicenseKey() in applicationDidFinishLaunching leads to Sorry! Your license token appears to be invalid. Please contact support with your OrderID if you believe this to be incorrect.

What am I doing wrong?

I am trying to zoom and pan the line graph in my macOS app the zoom is working but I am not able to pan through the zoomed graph its not at all scrolling and also I wanted to know how can I add click event on the graph so that I can display some more data on click at a particular coordinate apart from tooth. I have shared my view controller. I will really appreciate any help as I have spend a lot of time figure this out and have no clue where to go from here.

I was not able to find any sample code for macOS swift on gitHub to I tried to convert the iOS one for Mac and I grabbed the key from Scichart Licensing Wizard then initialised it in app delegates didFinishLaunchingWithOptions but I am facing this issue of invalid License token.

grab the code from here:

There are no simple macOS tutorial projects, so I transplant ios “Tutorial 01 Create Simple 2D Chart” to macOS one. (Attached file.)

Build and Run successfully. But no appear the coded chart. It seems that only SCIChartSurface is being displayed. (without axis and line series)
I enabled SciChart Console Debugging and got like this.

Why doesn’t the chart show up? Would you mind giving me some advice?

It seems that the file was not attached properly.
Please download the file from here.
