How Can i Load data from file.ecg and plot it ?

[ChrisW67]

There's no video tutorial because the instructions in the INSTALL file are both complete and adequate.

Since you have not explained the problem you are experiencing actually is we are unable to help.

thanks a lot,
I have done these steps to install QWT in my windows:
1.i downloaded the qwt library called qwt-6.0.1
2.unzipped it to C:/Qwt
3.then i started QT command prompt i found it in ( start > QtSDK > Desktop > Qt 4.8.0 for Desktop (MSVC 2010)
4.cd C:\QWT\qwt-6.0.1 this is the folder where i put the unzipped library
5.qmake qwt.pro this command executed successfully
6. when i try to execute nmake or nmake install i have this msg: 'nmake' is not recognized as an internal or external command, operable program or batch file

i stooped at this point can any body help me ?
thanks in advance

Try mingw32-make instead.

The Qt command prompt set the shell PATH to find the components of the Qt SDK. If, and only if, you are using the bundled MingW compiler this is also present in the environment.

You are using the Microsoft C++ compiler that expects a raft of stuff in its environment, the most important of which is the compiler/tool binaries in the PATH. When you use Microsoft's IDE this is all hidden for you (IMHO to the detriment of understanding). Microsoft, since at least the early '90s, provides a shell script called vcvars32.bat for Setting the Path and Environment Variables for Command-Line Builds (there may be a 64-bit version also). Execute this first after opening the Qt command prompt and you should find that things work better. You will need this to build Qt or any third party library, module etc. built from the command line: this is not unique to Qwt. I cannot tell you which version or where you have the Microsoft compiler installed so I cannot give you the exact command to type.

I think it perfectly reasonable that every set of install instructions for a library, like Qwt, assumes that the programmer has a working compiler environment. To expect otherwise is to expect the library author to have access to every possible permutation of system and compiler and produce a blow-by-blow set of instructions for each. Having done that you can be 100% certain that they will still not match some programmer's particular environment, and they will complain. The majority of blogs and other attempts to provide blow-by-blow instructions for Qwt fail in that way and generally demonstrate the lack of understanding of the author.

Before you start learning how to run, first you have to learn how to stand on your feet.
