This question is a follow up of this one. I am trying to run a command through the command line on a remote machine running Windows 7 from a workstation running Debian in an SSH session on that machine. The setup is basically as follows: debian box 1 === (SSH) ===> debian box 2 === (RDP) ===> Windows 7 I have tried running rdesktop from debian box 2 : rdesktop <Windows 7 box network address> -u username -p password -r disk:local="./TestRDP" -s "cmd.exe /K net use C: \\tsclientlocal & C:\test.bat & logoff" but cmd.exe is not launched on the remote device.

Assumed I want to draw three simple graphs based on the following illustration: How can I plot those three graphs? I've tried to create something like this: Minimum Working Example (MWE): documentclass{standalone} usepackage{pgfplots} begin{document} begin{tikzpicture} begin{axis}[domain=0:1] addplot+[no marks, samples=100] {exp(3*x)}; addplot+[no marks, samples=100] {(-exp(3*x)+20)}; end{axis} end{tikzpicture} end{document} Screenshot of the current state: Description of the issue: However, I don't get the point on how to figure out the function of the third graph as well as how to clip the graphs in x and y direction to align them centered in the plot. It is not necessary to be completely precise, the accuracy of my upper template w...
