Support Scala 2.12

unable to label panels

labels are too far from the plot area by default

custom grids are rendered outside the plot boundary

How to render plot o file?

I have looked at the examples in the file:

https://github.com/pityka/nspl/blob/master/saddle/src/test/scala/plots/plots.test.scala

But cannot get rendering to a file to work. I have the following code:

    import org.nspl.xyplot
    import org.nspl.scalatagrenderer
    import org.nspl.ColumnLayout

    import org.nspl.awtrenderer._
    import org.nspl.group


    val x : Seq[Double] = Seq(1d,2d,3d)
    val y : Seq[Double] = Seq(6d,7d,10d)
    val plot = xyplot(x -> y)(
      ylab = "y",
      xlab = "x",
      main = "main"
    )
    show(plot)

    val gallery: Build[_root_.org.nspl.Elems1[_root_.org.nspl.Elems2[_root_.org.nspl.XYPlotArea, _root_.org.nspl.Legend]]] = group(
      plot,
      ColumnLayout(3)
    )
    show(gallery)

    import org.nspl.awtrenderer.renderToFile

    renderToFile(gallery, 1000, "image/svg")

    renderToFile(plot, 1000, "image/svg")

The show call. The last two calls fail with:

[error] UFSpec.scala:1893: inferred type arguments [org.nspl.Build[org.nspl.Elems1[org.nspl.Elems2[org.nspl.XYPlotArea,org.nspl.Legend]]]] do not conform to method renderToFile's type parameter bounds [K <: org.nspl.Renderable[K]]
[error]     renderToFile(gallery, 1000, "image/svg")
[error]     ^

[error]     pngToFile(gallery)
[error]     ^

Here is my SBT build file

lazy val root = (project in file(".")).
  settings(
    inThisBuild(List(
      organization := "com.example",
      scalaVersion := "2.12.4",
      version      := "0.1.0-SNAPSHOT"
    )),
    name := "UFD",
    libraryDependencies ++= Seq(
      "com.github.pathikrit" %% "better-files" % "3.2.0",
      "io.github.pityka" %% "nspl-awt" % "0.0.19",
      "io.github.pityka" %% "nspl-scalatags-jvm" % "0.0.19",
      "org.scalatest" %% "scalatest" % "3.0.4" % "test")
)

Can anyone tell me what I am doing wrong?
BTW, is their a support forum or mailing list for nspl?

TIA

Parameters

Hey,

Any reason trait SimplePlots's class Parameters() is not a simple case class Params() ?

It seems you would benefit from the case class copy function, and Parameters does not need to be called by reference (at least I couldn't find where it would).

Not really an issue, just curious of this factory pattern.

Thanks in advance for your answer.

default axis label tick precision is not nice

legend renderers are not data dependent

align elements by pivot point

default line width too strong

text breaks on letters not words
