GNUPlot创建后立即消失 [英] GNUPlot disappears immediately after its creation

问题描述

我已经创建了gnuplot，但是问题在于它会立即消失.我尝试了其他线程中提出的不同解决方案，但没有一个起作用.解决方案1:注释文件GNUPlotParameters.java中的行bf.append("quit").append(NL);.解决方案2:将gp.setPersist(true);行放在gp.plot();之前.

I have created the gnuplot, but the problem is that it disappears immediately. I tried different solutions proposed in other threads, but none of them worked. Solution 1: comment the line bf.append("quit").append(NL); in the file GNUPlotParameters.java. Solution 2: put the line gp.setPersist(true); before gp.plot();.

DataSetPlot plotdata = new DataSetPlot(Xvals);
plotdata.setTitle("");
GNUPlot gp = new GNUPlot("C:\\Program Files (x86)\\gnuplot\\bin\\pgnuplot.exe");
gp.addPlot(plotdata);
gp.plot();
gp.setPersist(true);

那么，如何解决这个问题?

So, how to solve this problem?

P.S.我正在Windows 7上运行此代码.

推荐答案

不幸的是，这似乎是Windows下gnuplot中的错误. 请参见此错误报告.

Unfortunately this seems to be a bug in gnuplot under windows. See this bug report.

如果您想要这种类型的功能，则有两个选择:

If you want this type of functionality, you have two options:

1. 使用gnuplot的 CygWin 版本
2. 将结果保存到文件中，或使用 JPlot swing组件.

1. use CygWin version of gnuplot
2. save the result to a file, or use the JPlot swing component.

编辑:有一个新版本的JavaPlot应该可以解决此问题.

EDIT: There is a new version of JavaPlot which should fix this issue.
