to display the output in simple graphics like X-Y plot or some drawing...But I am not getting the right way to make the graphics. I want help for how to draw such graphics in linux...is there any inbuilt tool provided ? I got some information about the Glade & GTK+ ...is these tools used for developing only user interface or do they used for creating graphics? If this is the only option then how to link these userInterface & graphics with the C Code? Kindly send me ur suggetions...
