Draw process tree with gnuplot

由 岁酱吖の 提交于 2020-04-11 08:30:13
问题 similar to this question here I want to draw process tree where a PID is given, I should be able to draw that process and its children as a tree. However, I want to preserve parent children relationship between nodes/edges. What I mean is, any two children should not have edge between. Coordinates actually do not matter. Also, I am open for other drawing tool options. I tried the accepted answer of mentioned question but it links all nodes. Any kind of suggestion/help would make my day. Note:

brew install gnuplot --with-qt --with-x11 not working

问题 I tried installing gnuplot on a Mac (Mojave 10.14.2) using homebrew today, and it brew is not accepting --with-qt nor --with-x11 (I tried other variants, such as --with-qt5 and --with-x, with no luck.) brew options gnuplot did not report any options. How are we supposed to get the qt and x11 terminals installed on gnuplot now? 回答1: I contacted the brew maintainer who had most recently modified the gnuplot formula. Brew is no longer allowing options in formulas, so "brew install gnuplot --with

Can't find qt or x11 terminal gnuplot with CATALINA

问题 I installed gnuplot on my Macbook with Catalina 10.15.13. When I use it in Xcode it does not show me anything, it provides WARNING: Plotting with an 'unknown' terminal. No output will be generated. Please select a terminal with 'set terminal'. Having said that, I saw that to plot data I would need of the terminals qt or x11 which I do not have. The questions are two: How can I install them? homebrew does not allow me to use brew "install gnuplot --with-x11" In order to see the data, Do I have

年纪大了记忆力不好，有些不常用的软件总是记不住。特别是要在两个系统下切换（window和ubuntu），虽然大部分多媒体软件在linux下效果不如windows，不过咱作为码农也不需要那么专业。在此列个表帮助记录一下，此列表会不定期更新。 音频处理：audacity, ardour, lmms, adobe audition, Pro Tools 这几个都是功能强大的音频处理软件，前三个是免费的，在ubuntu下可以直接用apt安装。最后一个有免费版Pro Tools | First。 绘图： 位图：adobe photoshop, gimp, krita PS大名不用说，主要是linux下的替代品GIMP和Krita，在ubuntu下都可以用apt直接安装。 矢量图：adobe illustrator, coreldraw, inkscape, scribus 前两也很有名，不多说了。后面两个是linux下的替代品，在ubuntu下都可以用apt直接安装。虽然scribus实际上是用来做封面的，对标的是adobe indesign，不过用来画矢量图也能凑合。 微软画图板替代：pinta, kolourpaint 这两个软件纯粹是作为微软画图板的linux替代，有时候画点简单的图，或者简单处理一下，可以使用这两个软件。这俩软件均可以用apt直接安装。 录屏：obs-studio,

Mac OS X下GnuPlot的安装

Gnuplot是一个科学界广泛使用的作图软件，从Unix软件发展而来，是一款免费软件。因为其强大的作图功能，逐渐也有其他行业的人来维护支持这个软件，使其变的越来越流行。 Mac下的安装： Mac下的Gunplot有两个主要的形式：第一个就是Carbon二进制的文件，如果你运行的是经典的Mac OS系统（OS X之前），那这个可能是你唯一的选择。这个版本也可以在OS X下运行。如果你只是希望能够看到一个gnuplot文件的输出结果，而不需要安装软件到系统上，那么使用这个版本会非常方便。它不需要X-Windows或者其他的软件，安装简便，但是缺乏一些外部的控制。他还有另外一些特性： gnuplot for Mac支持多种苹果特有的技术。例如，gnuplot可以使用AppleScript或者被记录，支持PICT和QuickTime的电影格式，支持命令行编辑器，而且支持拖拽。仅能运行在Mac OS 8.6 系统之上，必须有Color QuickDraw、QuickTime、CarbonLib1.1或更高。程序在Mac OS 9.0，Mac OS 9.1 和 Mac OS X下测试通过。 Carbon Gnuplot的下载地址为： download 这个地址中也包含了很多非常有用的工具。 传统方式自然就是源代码编译安装。如果想在Mac OS下严肃的使用GNUPlot

Transparency for specific values in matrix using Gnuplot while preserving the palette?

由 隐身守侯 提交于 2020-02-15 10:21:54
问题 Here's an interesting problem: I have a 2D "matrix" of double-precision, binary data I'd like to plot using Gnuplot. This is easily done as follows: plot "foo.dat" binary array=384x384 format='%double' with image The trick is that certain "regions" of the data have a special value, say 1234567890.0. I want those elements to be fully transparent, and all other matrix entires to be fully opaque. Is there a way to set the transparency channel based on the data itself? I have looked through the

Gnuplot: power notation axis

由 六月ゝ 毕业季﹏ 提交于 2020-02-06 16:13:06
问题 I set the y-axis in power notation (1.0e+5 or 1.0 * 1.0^5) but I would like to report the power just on top of the axis to save space. In particular I would like to report at the end of the axis as reported in the link 回答1: I guess is very common to put the prefactor in the label (instead of top of the axis). If you absolutely need it on top, let me know. One way would be the following. There would also be ways to determine the prefactor automatically. Code: ### prefactor for axis reset
