Re: date display

Got it. You need to click 'as date' under the time axis specifications in the control panel.

date display

How doe I make the dates appear on the graph? I have added the dates in settings as per attached. But my graphs still show 0 - 365. Is there another step outside of 'settings'?

Graph Scale Reset

Hi,

How to reset graphs (when you click the graph button) to the full scale after you have used Shift & drag to zoom in on a certain time-bound?

Thanks

Re: Aging using subscript mapping

Ah yes, sorry I attached a version of the model which has 2 equations for average time in cohort , with 5 yrs for previous cohort and a very large number for the 100+ cohort. If you see the attached model I have simplified this to 1 equation in which average time in cohort simply equals 5, and you c...

Aging using subscript mapping

I'm trying to age the population, and in the attached test model I would expect the age band 100+ just to grow (but it doesn't, so where are those people "aging-out" to?) ....is there a way to write the equations more elegantly than just writing a separate equation for the 100+ population,...

Re: Problem Installing Model Reader

Because the .vpa files didn't change to display the Vensim logo, I assumed that it actually didn't install correctly.

We are still working on this...thanks for your support.

Vensim Get Data with subscript

Hi, When I use Vensim_Get_Data, I find that I must put the subscript element in the variable name, I can't put the actual name of the subscript range and get all the output. Any advice on how to simplify this process and just use the subscript name to get data on all the elements? Many thanks, Sarah...

Hi, I'm looking for a bit of clarity on importing data... (1a) When you save a data variable as a .vdf, does it just save that variable? (1b) Whereas when you save a simulation run as a .vdf it saves values for all variables in the model? What's the best way to import a subscripted data variable (wi...

Loading changes file in model reader

Hi,

I'm guessing it's not possible for a user of Model Reader to load different changes files?
If the scenarios are driven by the .cin files, is there any way around this?

Many thanks,

Re: Problem Installing Model Reader

Hi,

Actually it means that the Model Reader doesn't install. Plus, he needs the .dll to work. Hmm. I guess I can troubleshoot with him for awhile. Try to get him to use the default settings.

Thanks for your help.

Re: Problem Installing Model Reader

I am pretty sure that it is defaulting to these settings. Perhaps because of a past installation where the user tried to use the faulty settings too?

Re: Vensim.dll not working on guest computer

Oh thank you! This is really interesting. The solution I eventually came to was to use the phrase: call interface.xlsm and I didn't embed the interface in the *.vpa published package at all....so they exist as two files. This was the only way I could stop the over-ride error message. Your solution d...

Re: Vensim.dll not working on guest computer

Hi Tony,

I don't really know how to write a batch file. Here is my attempt.
It's obviously wrong, all I wrote is literally:

@echo off
launch interface.xlsm

The model doesn't seem to open either.

Thank you. I think your suggestion will work if I get this file right.

Best wishes,

Re: Vensim.dll not working on guest computer

Hi Tony, I don't mind distributing two files, but the problem still persists - because the only way to package the .vpa is to use the interface.xlsm files as the caller. So the .vpa opens the interface.xlsm from the package and then saves the interface.xlsm to the same folder as the .vpa.....I don't...

This is the error I'm getting every time I simulate. Clicking "No" works around it, but very distracting.

Ah, ok - I worked this out. For reference, it wouldn't package interface.xlsm because interface.xlsm was open (set to open automatically when you open the model.)
