windows平台使用python 调用gnuplot画图后窗口不能保持

aidixiao

使用下面的代码:
#!/usr/bin/env python
import Gnuplot, Gnuplot.funcutils
from numpy import *
gp = Gnuplot.Gnuplot()
gp('set data style lines')

data1 = [[0, 0], [1, 1], [2, 4], [3, 9], [4, 16]]
plot1 = Gnuplot.PlotItems.Data(data1, with_="lines", title="Quadratic")
data2 = [[0, 0], [1, 1], [2, 2], [3, 3], [4, 4]]
gp.plot(plot1,data2)

能正常画图,就是画完后窗口一闪就没了,在gp = Gnuplot.Gnuplot()括号内加persist=1参数的话,又显示错误,
"gnuplot persist is not support in windows",想向各位大侠请教一下,通过什么方法使画完图的窗口保持住.
谢谢了.

我也遇到同样的问题。
def plot(energies):
    from Gnuplot import Gnuplot, Data
    p = Gnuplot()
    d = Data(range(len(energies)),energies)
    p.plot(d)
    return
   
data = [1,2,3,4,5]
plot(data)

我找到一个答案了
On some platforms, some backends may result in a plot that is shown in just a fraction of a second on the screen before the plot window disappears (using the Gnuplot backend on Windows machines or using the Matplotlib backend constitute two examples). To make the window stay on the screen, add
raw_input('Press the Return key to quit: ')
at the end of the program. The plot window is killed when the program terminates, and this satement postpones the termination until the user hits the Return key.
