Re: Using scala variables in html

[Wood, Dean Jr (GE Oil & Gas)]

Hi Moon,

Thanks for the quick response. My problem with my approach is it doesn’t work. 
When I package it up and then call it from zeppelin with
{
    import zep_plot._
zep_plot.zepplot.plotter
}

it prints out the html and doesn’t display the plot. What am I doing wrong?

Hi,

Will String interpolation helps?

And i think your approach is very valid.

Best,

Hi,

I’m having some issues with getting a html file which plots a line graph using 
D3 to plot using some scala variables. My html is rubbish so it might be 
something straightforward.

I have a simple package built with sbt containing the following:
package zep_plot

import com.google.common.io.Files


package object zepplot{
        def plotter():Unit= {
        val x1=Vector(0, 1, 2, 3, 4)
        val y1=Vector(0, 1, 2, 3, 4)
        val x2=Vector(0, 1, 2, 3, 4)
        val y2=Vector(0, 1, 4, 9, 16)
        val text1 = com.google.common.io.Files.toString(new 
java.io.File("/Users/deanwood/Documents/scala/plot/src/main/scala/file1.html"), 
com.google.common.base.Charsets.UTF_8)
        val text2 = com.google.common.io.Files.toString(new 
java.io.File("/Users/deanwood/Documents/scala/plot/src/main/scala/file2.html"), 
com.google.common.base.Charsets.UTF_8)
        println("%html"+ text1 + x1(0) +","+x1(1) +","+x1(2) +","+ x1(3) +","+ 
x1(4) + "], y: ["+ y1(0) +","+y1(1) +","+y1(2) +","+ y1(3) +","+ y1(4) + "] }, 
{ label: \"Data Set 2\", x: ["+ x2(0) +","+x2(1) +","+x2(2) +","+ x2(3) +","+ 
x2(4) + "], y: ["+ y2(0) +","+y2(1) +","+y2(2) +","+ y2(3) +","+ y2(4) + text2)
 }
}


I’ve broken the html file in two and tried to replace the part where I inserted 
the data in the javascript with variables defined in scala on zeppelin. I’ve 
attached the html below.

The ultimate aim is to be able to provide some standard plots which will 
dynamically take RDDs defined in zeppelin and plot them with enhanced plots not 
currently provided by zeppelin. The aim is have an interim fix until the mooted 
summer of code project hopefully enhances zeppelins plotting capability. So, to 
make this interim solution work, how do I get scala variables plotted in the 
javascript of a html file. I’d like the info on how to use the variables as I 
want to do the same thing for a heat map and a couple of other standard plots 
required for my project. I’ve attached the example html files used in the scala 
package below.

Thanks for any help.
