@amoss To be honest, the best one will be the one that meets your need simply. But what you can evaluate is the size of code each will “weigh” in your application.
Apexchart pleases me the most for the amount of customization features it brings me. But that is a personal opinion.

@amoss

Here is the default library: https://www.chartjs.org/docs/latest/getting-started/installation.html

This is the library for Vue.js, so I would certainly use the second one for ease: https://github.com/apertureless/vue-chartjs

@amoss What do you think of these examples?

@mboeni To use the tray icon for example, I decide to follow the way:

electron-main.js

if (process.env.PROD) {
  global.__statics = require('path').join(__dirname, 'statics').replace(/\\/g, '\\\\')
}

let tray = null
app.on('ready', () => {
  createWindow()
  tray = new Tray(__statics + '/icon.ico')
  const contextMenu = Menu.buildFromTemplate([
    { label: 'Fechar', type: 'normal', click: closeWindow  }
  ])
  // mainWindow.minimize()
  tray.setContextMenu(contextMenu)
  mainWindow.hide()
})

@mboeni Hello! In Electron static assets work in a particular way.
