Dushyant,

I'm not totally clear on what's not working for you.  It just looks like there is a small offset between your graph and your image.  You should be able to drag the picture control down a little and have the grid line up right.  You could similarly just change the "bounding rect" input of the "Draw Cartesian Axes.vi" to move the graph around.

Thanks a lot for your help.

It mostly worked. However there r some minor issues.

I added a new subvi named axis property which basically uses “Draw cartesian Axes.vi”.

I have added two different spreadsheet. In folder “data 1”, the main spreadsheet is “Full_Scan”. While in other the main spreadsheet is “Fine_Scan_5”.

Please display both the image one by one. While for “Full_Scan”, it would display fine; but for “Fine_Scan_5”, the display would be quite messed.

I am attaching all my codes in zip file as I have modified main vi and added another subvi.

I am also attaching apreadsheets.

Thanks,

Dushyant

Dushyant,

I tried to run your application and I could not get it to run.  I pointed it at one of your spreadsheet files and it gave me an "Error 7: File not Found".

I believe that there may be problem is some code. I am attaching files again.

Let me check why it's not able to open the spreadsheet.

[Dushyant]

I think that you open the wrong file. There are two spreadsheets in each folders, one in each folder contains scan information and the extension
is .xls. The file that you should display is:


Full_Scan (in folder 1)


and

Fine_Scan_5 (in folder two)

Dushyant,

I was able to run your program.  I was targeting the xls files instead of the files w/o an extension.  Your problem is that you have a race condition in your code.  You are reading the value of the indicator "Pixel Sizes    of Picure" in a local variable before the value is calculated.  When you do this you are just reading the previous value of the control.  This is why, when you run the program twice in a row with the same file it will work fine.  If you connect this indicator directly to the input of your "Axes_Property" VI rather than using a local variable, it seems like your program runs fine.

Thanks Justin.

However, it did not solve the problem. Please open the attached word document and it would explain my problem.
