plotting a binary file by using Qwt

[Alex22]

You have to "parse" your file first, so you become two arrays, one with time and second with values.
Then it is easy to pass these data to a Qwt curve object.

no i need my project to work fast whit out any parseing or converting

But you have to read the data from the file somehow.
Do it by 4 bytes (quint32 for example), pack them into two arrays and pass to the plot curve.

thanks, but 4 bytes are little. i need put them binary data) from file in "char c[1024]" and then cast each byte (each cell) of "c" to float and then plot all. please help me in this way.
