Plotly for Scala User Guide in Scala

User guide to the Scala Plotly client

 Setting credentials programmatically

The simplest way to pass credentials to the Plotly client is through the credentials file. However, we sometimes need more flexibility. The Scala Plotly client lets you set credentials within your program:

import co.theasi.plotly._

implicit val server = new writer.Server {
  val credentials = writer.Credentials("DemoAccount", "lr1c37zw81")
  val url = ""

val p = Plot().withScatter(Vector(1, 2), Vector(3, 4))
draw(p, "custom-credentials")

The draw method looks for an instance of type writer.Server that is present in scope. Let's, for instance, write a program that asks the user for a username and password and sends a graph to their account:

import co.theasi.plotly._

object PlotlyDrawer extends App {

  // Generate random data
  val xs = (0 to 100).map { i => Random.nextGaussian }
  val ys = (0 to 100).map { i => Random.nextGaussian }

  val p = Plot().withScatter(xs, ys)
  val plotFile = draw(p, "credentials-demo", writer.FileOptions(overwrite=true))
  println("Plotted graph at:")
