this is a follow up to my question titled 'Draw Graphs'...
commercial toolkits are out of the question bcos my school project does not have a budget for it (such toolkits cost money rite??)
pls forgive me for i have just started learning VC++.... so can you kindly explain in more details the following:
1) Drawing of grids using the LineTo, TextOut etc etc functions.
2) For the program to generate the graph... let say i got two variables, theta and displacement, i will calculate the displacement at certain interval of theta. eg, at theta equal to 5, 10, 15, 20.... displacements are d1, d2, d3, d4. as such i would have the various pts. question is, how do i map this points into the grid i have drawn?? also, how to i join this various pts up after i mapped them into the grid i drawn??
the project gonna due very soon and i just can't seem to solve the problem. your help is very much appreciated. thanz in advance.
