Please note that, currently at least, this add-in only works on graph objects. If you are looking at a graph view of a series or a group, the add-in will not appear/work. However if you hit the freeze button from that view, to create a graph object, you can then use the add-in.

Hi Gareth. We have had some stability issues with EViews that will cause the EViews window to disappear.
I was unable to send an example because of secure data. When I tried to change the data EViews didn't blow up.
The program I ran used a lot of string and svector objects, with a lot of parsing using @wsplit, @replace, .... All this to build up tables.

So, when trying to run the RecShade add-in EViews disappeared.

Here's all I did:
Open a new EViews window.
Open the workfile macromod.
Open the GT graph object.
Click on Proc.
BOOM, EViews disappears.

EViews Version 7.1
Enterprise Edition - Apr 20 2010 build

Just so I'm clear - you were running a program you had written yourself, then you ran the add-in on a workfile, and EViews crashed?

Had you run your program a few times where it had stopped because of an error?

[TimGrun]

Sorry Gareth, I was very unclear in my post.
There are two separate issues. The first was with an example that I was unable to send to you.

But then, a completely separate issue, was the bombout when trying your RecShade addin.
I had run your RecShade addin example with a brand new EViews session. I was following the example in the EViews 7.1 Supplement help document when my EViews session disappeared. I retried it several times showing other people (to prove I wasn't crazy ). Later, I reinstalled the add-in and now the RecShade add-in works.
Even if I am making some mistake, the EViews session shouldn't just disappear. Unfortunately, I have been unable to find an easily replicable situation that causes EViews to bomb out(disappear).
The next time EViews disappears I will try and send you something that will demonstrate the problem.
Has anyone else reported problems with an EViews session disappearing?

Thanks,
Tim

No, you are absolutely correct, EViews should never crash like that, even if the user has made a mistake. Unfortunately it can be hard for us to fix those crashes without replicatability.

Obviously one thing I can suggest is that you keep your copy of EViews 7 as up to date as possible, we fix bugs as soon as we find them and usually release a patch fairly soon afterwards.

[EViews Gareth]

Out of interest, when EViews disappeared, did any error message pop up, or was it just a complete vanishing?

[TimGrun]

It was a complete vanishing or I would've sent you the error message.

Note that Bob Hall has screwed up RecShade.

[EViews Gareth]

I updated the programs on Monday to reflect the latest info (just didn't post here to tell you).

Shoulda known...

Hi All

I use this add in often & it's great

however, how can i change the shading color? (alternatively - is there a default shade option i can manipulate - so that my chosen shade is the default shade?)

thanks much

Wes

If you open the Add-in program, you'll notice there's a ton of lines that say

Code: Select all

g1.draw(shade, bottom)


Change those all to be

Code: Select all

g1.draw(shade, bottom, color(green))


to change the colour to green, etc...

Javier Sanchez Barrueco has updated this add-in so that it now supports Japanese recession dates. If you download the add-in it will now ask you which countries you would like to install.

If anyone else would like to contribute other country's official recession data, feel free!

[w_nawfal]

that's great - thanks to Javier

if i come across official recession data for other countries via my work i'll certainly update this add-in :O)

cheers
