GRAPH 3D v2.425 (20-FEB-2017)

I am typing it in exactly as you have it on your video. I also have updated my Firmware to the most recent as well. I checked the program on the calculator and i get errors too. is that normal? I opened it with wordpad like you said and copied and pasted it into the programming part after i went into apps copied the advanced graphing and renamed it Graph3D. Any suggestions?

You wrote about "typing it in exactly" as I have it in my video, are you referring to the formulas to plot? Is the error occurring after you try to enter the formula? As far as I know, apps do not report runtime errors so pressing the [Plot] key either works and shows a graph, or nothing appears to happen (no error messages). So if you are getting invalid object when trying to enter a formula, my guess is that you are in RPN mode and need to add single quotes around your formula.

I'm also confused as to how you are able to directly copy the source code onto the calculator. Did you mean that you copied the source code into the emulator while the program editor was open? (And is the emulator up to date?) If so, and exiting the program editor resulted in syntax errors, could you share what the error messages are? Also, if you press "Check" while the program editor is active, it will not only report the error but move the cursor to the error position. Know which line of code causes the error will help determine the issue.

If you can you explain a little more about when/where the error occurs, and what your Home settings are, it would make it easier to figure out what is wrong.

I Found the error. I went through and looked at it and it looks like originally i pasted the code twice. So i deleted the second half and now i dont get an error. However i do have a few questions. How do you trace? I am watching your videos and it looks like you are hitting the Number 5 and it is tracing but i am trying that and it wont. And also is it set up that when you enter the formula it is Z=... where Z is V1? So for example i plot X+Y. Is it really plotting Z=X+Y?

The trace feature is in the version labeled polytrace, in the first post of page 2; you can also just click the link below:

http://www.hpmuseum.org/forum/thread-95-page-2.html

Just tap the screen then it brings up the menu of options. In the video, you were seeing an unreleased version in which I mapped the 5-key to pull up trace mode.

And yes, if your formula is V1:X+Y then it is plotting Z=X+Y.

Thank you for all your help. I have one last question, sorry. On the emulator, i can click the screen and the menu pops up like you said, however on the calculator itself it just exits immediately. Is that feature only for the emulator?

Could this possibly be relevant to your issue?

http://www.hpmuseum.org/forum/thread-95-...ml#pid2478

The behavior of the touchscreen seems to indicate you still have an old version of the program on the calculator.

[wrister05@aol.com]

Thank you! I looked at the date and it said Jan-9-2014 but i deleted it and re-downloaded it and re-installed it and everything looks the same but now the touch screen works. Thank you again! its an awesome program!!!

I am having the exact same error show up as Wrister05, but i did not double paste! I tried sending from connect kit and emulator and its not working. Everytime I do one of the above, and I plot ANY function and it gives the "invalid object error". i checked from within the calculator and sure enough there was a syntax error at around line 353. This however does not happen on the emulator only on the physical calc after sending!

"I Found the error. I went through and looked at it and it looks like originally i pasted the code twice." Can u confirm where you found the error? I am having EXACT problem as you, i doubt you pasted the code twice, chances are the system messed it up during the transfer process and i cant figure out whats causing the program to run into a syntax error when its on the physical hardware.

[wrister05@aol.com]

Have you tried deleting it all together and redoing it including re downloading? And are you opening it with wordpad? That's also what I ended up having to do.

Hello Han.
I have downloaded the file that you uploaded, and did the same thing you show in the video, but when I click the check button. That always shows Syntax error in program line 357. Could you help me?

Can you share what the actual source code on line 357 is? (The cursor should automatically be placed on the error) If the line is too long, just a snippet will do.

What method did you use to send the code to the hardware? And what is the line of code that gives a syntax error (not the line number, but the source code itself)?

I think im doing exactly as said,but i have a message "Error:Invalid object" when plot the graphic too.

1. What function were you trying to plot?
2. Do you have complex mode enabled?
3. What number format setting are you using?

I am a bit surprised that you managed to get any error message. Apps currently do not trap errors like programs. If you get an error while running an app, the app just stops and nothing is reported to the user.

There is clearly a huge discrepancy between the source file that you included in a previous post (just above this one) and the code that is shown in the screen shot. It looks as though the screenshot shows a different version than the one whose source you listed.

So in addition to my previous questions:

Quote:1. What function were you trying to plot?
2. Do you have complex mode enabled?
3. What number format setting are you using?

can you also share

4. What firmware do you have?
5. What version of Graph3D are you trying to use? no rotation? with rotation? with rotation and trace?

Hello,

I am having the same problems of wrister05 and lala.

The app works fine on the emulator but I always get the Invalid Object Error when I try to plot any function on the calculator.
I have already tried to transfer the program using the Connectivity Kit and the Emulator but this error still happens.

I have already redownloaded everything and I am using the Wordpad. All the firmwares are up-to-date. All the Setting are default.

How did you fix that problem?

Han,

1-the function you used in your first post 1−(cos(X²+Y²)/X²+Y²)
2-sorry,im new with hp prime and i don´t know if i have this enable,how can i see this?
3-i dont understand what is this,can you tell me a little more please?i will search 2 and 3...
4-i think this is the knewest firmware is 2013 11 25 (5447) and cas version 1.1.0-27
5-i should said this before i tried every possible version (haha).what version do you like me to try?

thanks,
Daniel

Han,

see those screenshots please.

1- the function
2- the Symb settings,this is the setting i think you said like complex mode and number format (i tried all them)
3- the error when i press plot to 1(the function)
4- after the error the plotted graph

i dont know what to do...

this time i am using your 2.1 version.i think if i would be able to use one version,i would be able to use all others.

thanks,
Daniel

There are three version, each with slightly different abilities (these will all be merged into a single release with the next firmware update).

Your screenshots suggest that the app was not properly installed. A properly installed app would never show the screen featured in your screenshots, because the source never actually calls that screen (in any version). Would you humor me and check to see whether the app was actually properly transferred? Simply go to the program editor (while in the Graph3D app) and at the very top should be "Graph3D (App)". Select it and press ENTER to open the file to see the contents. If you don't see much of anything, then the app was never transferred properly (the connectivity kit can sometimes be quite unreliable).

Among the three versions, the polytrace one has the most features and is the most robust in terms of domain handling.
