我需要通过gnulot从数据绘制图形

Question

我有这些数据示例：

(cur | prev) 01:22, 30 March 2011? Sergio (Talk | contribs)? . . (20,789 bytes) (+4)? . . (>?VoIP)
(cur | prev) 01:23, 31 March 2011? Sergio (Talk | contribs)? . . (20,790 bytes) (+1)? . . (>?VoIP)
(cur | prev) 01:25, 01 April 2011? Sergio (Talk | contribs)? . . (20,950 bytes) (+160)? . . (>?VoIP)
(cur | prev) 10:15, 05 April 2011? Tcatm (Talk | contribs)? . . (21,028 bytes) (+78)? . . (>?Virtual goods)
(cur | prev) 12:43, 06 April 2011? Doood (Talk | contribs)? . . (21,173 bytes) (+145)? . . (>?Home)
(cur | prev) 12:43, 08 April 2011? Doood (Talk | contribs)? . . (21,162 bytes) (-11)? . . (>?Home)
....

我想画历史图。 我必须在x轴日期（以月为单位）和y轴行数上进行记录。 示例：x轴=“ 3月” y轴=“ 2” x轴=“ 4月” y轴=“ 4 + 4月（及之前的几个月）”。

我该如何通过gnuplot做到这一点？

Answer 1

这可以通过在绘制时使用“ smooth cumulative选项来实现：

set xdata time
set timefmt "%B %Y"
set format x "%B %Y"
set xtics 24*60*60*30
plot "data" u 6:(1.0) smooth cumulative with lp pt 7

作为timefmt我仅使用完整的月份名称和年份，而忽略日期，以便将三月的所有数据点相加，然后对四月的三月和四月的所有数据点求和，以此类推。使用以上数据，您将获得以下内容输出图像：
