this is rather a followup from my other post…in the attempt to try and  
graph a quick sample data i get richeous errors lol.

require ‘rubygems’  
require ‘ruport’  
require ‘ruport/util’  
require ‘tempfile’

class GraphReport \< Ruport::Report

```
    renders_as_graph

```

isp1r = []  
isp1 = Tempfile.new(‘tempisp’)  
isp1.puts File.readlines(‘maindata.csv’).grep(/Blah1/)  
isp1.each do |row|  
isp1r \<\< row[“AVERAGE”]  
isp1.close

def generate  
graph = Ruport::Graph(:column\_names =\>  
%w[24,23,22,21,20,19,18,17,16,15,14,13,12,11,10,9,8,7,6,5,4,3,2,1,0])  
graph.add\_line [isp1r], :name =\> “Blah1”  
graph.add\_line [14,54,22,54,12], :name =\> “bar” # Just an extra line,no  
reason  
return graph  
end  
end  
end

puts GraphReport.generate{|r| r.save\_as(“filename.svg”)}

###### 

theoretically this should have generated 2 lines, 0 - 24 on the bottom  
of the graph, and the Blah1 grep data up the side.

instead i get some awesome errors

No offence, but there are a lot of problems with the script you  
posted! Check your do/end pairs and your usage of tempfile. I still  
don’t think you need a temporary file though, because Ruport/  
FasterCSV can parse from a string.

Using this csv file:

Name,Average  
Bill,2  
Bob,1  
Blah1,10  
Jill,3  
Jane,4  
Blah1,20  
Ada,6  
Blah1,30  
Ruby,7  
Blah1,40  
Sigfried,2  
Blah1,50

Does this code help?:

require ‘rubygems’  
require ‘ruport’  
require ‘ruport/util’  
require ‘tempfile’

class GraphReport \< Ruport::Report

renders\_as\_graph

def generate

```
 data = File.readlines('filename.csv') #Read in csv (into Array)
 head = data[0] #Take header line
 data = data.grep(/Blah/) #Grep out lines we are interested in
 csv = ([head] + data).join #Combine the header and lines back

```

into a String

```
 table = Ruport::Data::Table.parse(csv) #Parse into ruport

 graph = Ruport::Graph() #Plot
 graph.add_line table.column('Average').map{|x|x.to_i}, :name =>

```

“Blah1”  
graph.add\_line [14,54,22,54,12], :name =\> “bar” # Just an extra  
line,no  
return graph  
end  
end

puts GraphReport.generate{|r| r.save\_as(“filename.svg”)}

lol alright that worked out pretty nicely, but how would i align the 24

- 0 with the Times that Blah1 is set at:  
EX:

Time–Average–Name  
14:21 3.42 Blah1  
13:45 2.12 Blah1

### 

so i need to align 14:21 with 14.21 on the graph

n-e ideas?
