Re: Data import: Interpolate but not Extrapolate..?

Can you upload an example? I'm not sure I understand what you want to do.

At a guess, you can mark the imported data as RAW. Then use IF THEN ELSE, maybe something like

interpolated data := imported data

data to use = if then else (imported data = :NA:, interpolated data, imported data )

Re: Error installing the academic version of PLE

Haven't heard of this before. Try the usual things. 1. Restart the computer. It seems Mac users rarely restart, this often fixes a lot of things. 2. Run a virus scan. 3. Download Vensim again and try the new download. 4. On the hard drive, do a "check permissions" (I think on later Macs this has cha...

Re: Scale of Y-axis in standard Vensim graphs

Not really. The general purpose graph tool needs to work with all variables and all scales. The custom graph already exists to do things like this.

Re: Use of the TREND and DELAY functions in Vensim

I don't think there are videos on how to use these functions.

What part of the documentation are you struggling with?

Re: Window resize does not work

The best way to do this is to view the project properties, then click the Advanced button. One of the tabs here is titled "Screen Size", set the size for the project here.

Re: memory allocation error

How did you make Vensim crash here? I've tried pasting in 30k x/y pairs of variables and Vensim is fine, it only allows a certain amount of characters in the edit window. Did you paste these values into the text view of the model?

Re: memory allocation error

I'll see if I can enable more memory for this.

You could try putting the values into a CIN file. Or even better, as an external data source (save as a CSV and import using Model->Import data).

Re: Test Screen vs Run Venapp

Can you upload the files? Screenshots are useless, we cannot tell anything that is wrong.

It could be that you have not loaded the model properly, or they are gaming parameters (but no game is in progress). Could be a number of different things.
