[Chartjs]-Plotting multiple lines (line chart) in Apache Zeppelin using AngularJS

3👍

We can do a model transformation from one DataSource (for example Spark DataFrame) to the Chart’s model which %angular supported by Zeppelin. You can doing similar like this SO create a multi line chart using Chart.js

If doing this way, then every time when we want to change to a different model. We have to do copy & paste work. It will be easier if there is a general model transformation.

I created a repo on github spark-highcharts for plot easily for spark DataFrame with Highcharts. You can plot with spark-highcharts after doing a simple transformation from Scala collection to Spark DataFrame if you could accept using Highcharts.

Like the following code to create multiline chart.

import com.knockdata.spark.highcharts._
import com.knockdata.spark.highcharts.model._
import sqlContext.implicits._

val Tokyo = Seq(7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6)
    .map(("Tokyo", _))
val NewYork = Seq(-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5)
  .map(("New York", _))
val Berlin = Seq(-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0)
  .map(("Berlin", _))
val London = Seq(3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8)
  .map(("London", _))

val dataFrame = (Tokyo ++ NewYork ++ Berlin ++ London).toDF("city", "temperature")

val chart = highcharts(dataFrame
  .seriesCol("city")
  .series("y" -> col("temperature")))

chart.plot()

Multi Line Chart

And the API is pretty similar between Highcharts and ChartJS. A similar library could be done to transform from Scala collection to ChartJs similar like spark-highcharts does.
