inconsistent xrange behaviour with time data #19
Description
I have simplified an example as far as I could :
require 'gnuplotrb'
include GnuplotRB
#x = ["2013-05-22 02:49:49", "2013-05-22 02:56:49", "2013-05-22 02:56:59"]
x = ["2012-05-22", "2013-05-21", "2013-05-22"]
y = [ 2,5,9]
p x.first
p x.last
element = Dataset.new(
[x, y],
with:'lines lw 3 lt rgb "black"',
xdata: 'time',
timefmt: "%Y-%m-%d", # timefmt: "%Y-%m-%d %H:%M:%S",
xrange: '["2012-05-22":"2013-05-22"]' #xrange: '["#{x.first}" : "{x.last}" ]'
)
myBRTraces = Plot.new(
element
)
p myBRTraces.inspect
myBRTraces.to_png("/media/sf_D_DRIVE/Test/a.svg", size: [1200, 1800], truecolor:true)behaviour:
$ ruby test.rb
"2012-05-22"
"2013-05-22"
