Gruff: In line graph I need lables at every dots

I am implementing Line graph. I want to have labels just above every dots inside graph. Please help me to implement.

require 'rubygems' require 'gruff' graph = Gruff::Line.new("594x384") graph.theme = {        :marker_color => '#aaa',        :background_colors => ['#ffffff', '#fff']      } graph.y_axis_increment = 100 graph.replace_colors(['#999999','#bbd65b','green']) graph.data("first", [100,190,110,230,460,400,550,450,620,300,470,140,1000]) graph.data("second", [400,500,420,580,580,680,830,500,900,600]) graph.legend_font_size = 15 graph.marker_font_size = 15 graph.title_font_size = 15 graph.line_width = 2 graph.dot_radius = 3 graph.labels = {   0 => '12AM',         2 => '4AM',         4 => '8AM',         6 => '12PM',         8 => '4PM',         10 => '8PM',      }    graph.minimum_value = 0    graph.y_axis_label= "Number of Impressions"    graph.x_axis_label= "Time" graph.write('my_graph.png')

What have you tried, and what isn't working?

require 'rubygems' require 'gruff' graph = Gruff::Line.new("594x384")

[...]

This question has absolutely nothing to do with Rails, and so it's off topic here. Please ask in the Gruff forum if there is one, or failing that in the Ruby forum.

Best,
