I am trying to plot the number of times specific memory addresses has been accessed. I have recorded this in an xml file with the address and the count with a space delimiter(it does not need to change over time) . How would I go about plotting these specific points using QWT? I have tried putting simple arrays (i.e. double yy[] = {1,2,3,4}) and plotting these but have come up with no success. I am very new to QWT, much less QT, much much less coding in general! However, a simple example of plotting specific (x,y) points would greatly help me. Thanks!
