-
Sure. I'll use it and take a video. The point is that the filters on an Excel Tab, with plots derived from a set of independent Pivot Tables, affects all of the plots. We can't (yet) do that, because Ravels are currently related just to the slice already taken from the source data. Best, Steve Professor Steve Keen Want to rebuild economics?

Unfortunately not! I'm using Minsky 3.8.0-alpha.3 Minsky GUI 3.8.0-alpha.3 Ravel 1.3.1: Expires in 72 days Angular 17.3.7 And I just triggered it again. MP4 too big to attach directly; coming in the next post.

At least I found a minor bug! When you resize an edit mode Godley on a publication tab, it resizes from the middle or thereabouts of the Table, rather than from its other edge.

My bad! I didn't try the right-click menu to toggle to Editor mode. My apologies Maestro!

Finally got the intended result. I hope I've uncovered something buggy in the code in the process. The exercise has emphasised the desirability of a running sum and a running average operator. In terms if icons, maybe indicate them with arrows <--> above the current cumulative sum and average operators?
-
I just re-triggered it by resizing windows.
-
Replace the old running sum operator with the new one and everything is fine.
-
Here's another comparison. The original operator doesn't work, with the same settings on which the new one does.
-
Strange! I added a new running sum, and it worked with that. But it's still not working with the older one.
-
I did that. See image and RVL file.

Moving average operator

I managed to trigger this bug myself by resizing Ravel's window, so--as I expect you've already worked out--it's a scaling bug issue again. One of these videos also illustrates another bug: an error message for a difference operator that persists even though the error (not specifying an axis) has been addressed. I'm leaving this in this ticket because there's a chance these bugs are related.
-
Here's the recording of our Zoom session. I got him to open, try to import, shut down, reinstall, and the same error applies. After the initial error message on loading Ravel, nothing works: not even typing a divide by key, let alone inserting a data import parameter. He's a good friend, so I can link you two for you to suss out what's happening. It must be specific to his PC (Windows) but this is a problem we don't want anyone to experience. video1715194963.mp4 https://drive.google.com/file/d/1_gY35hjK-x5DY0WITP40FCRnZ38IBr7b/view?usp=drive_web...

Crash on Loading Horizontal Data

Ah! What I actually did was define GDP as a parameter, and then put it into a Ravel using the merge operator, then--here's the error--attach it to a variable that I also called GDP. Ravel caught the error, so I then renamed the variable GDP_{Nom}. Thanks. I'll go back and redo that file. Best, Steve Professor Steve Keen Want to rebuild economics?

Divide Operator Glitch
-
The merge operator seems to be scrambling data somehow. A division of one parameter by another returns the expected result. A division of one variable by another, both derived from a merged Ravel, does not.

I'm only getting Ravel 1.3.0 when I choose Upgrade.

Let's go for the parameter edit then. Can you bump it up to 10? An option can come later, as you say. I'm starting social media posts tomorrow BTW. And I might contact a friend who runs a game marketing company as well.
-
Yeah, but now with the improvements we made to axis labelling and such in the last year, six is no longer the maximum. I'd say it's about ten. Can that parameter value be changed in the code? At some point, we could make it a user-option, but in trying to show off Ravel in social media posts, the faded display is more of a hindrance than a help.

Good. Even a minimum size warning would help, since 2^64 is a much bigger number than most people appreciate. Something that gave users an indication of potential data cube size? Maybe a box like this: Dimensions: Max number: 21 (this is the initial size of the BIS database) Est. minimum for unique key: (user entered--7 for the BIS) Max values per dimension: 350 (that's roughly the number of quarters) Min values per dimension: 2 (Adjusted or unadjusted for breaks) Estimated data cube size (calculated...
-
OK, but I have to sheepishly say... that I think my idea of a "greyed out" Ravel when there are more than six dimensions was a mistake--or rather a relic of when the angles of the axis labels and the text clashed with each other. This is now an annoyance when I load the BIS debt data for a video, since it come in as seven dimensions. I have to reduce by at least one dimension before what a Ravel looks like is obvious in a recording. Could this effect be bumped up to say ten dimensions, as a temporary...
-
OK, but we do need to warn users of when they are likely to breach "curse of dimensionality" limits. Could you include a calculation field showing the data requirements of current selections? This could be used to advise users to reduce dimensionality on importing by choosing to ignore sufficient columns while still generating a unique key.

I didn’t enter a value though. That must be the consequence of attempting to move the legend using the mouse.

Yes, but what happens if we have two time series then, one with something that fits the ISO standard and one Quarterly? Will they be treated consistently, or will one bugger up the other? Pardon my mood! My expensive USB microphone has just failed one day before the bloody YouTube Pitch. I'm now going to go back in time and kill Murphy.

Invisible Wires

I think I've worked out what's going wrong. When you don't specify the date format, the program seems to treat the Quarter numbers as months. So what you get is data for January, February, March, April, and then the next January-April. Instead what you should have is data for January, April, July, October, then the next January, April, July, October. Of course what different countries choose as months for quarters is probably also arbitrary! But in this case I think it would be best to use the American...
-
Fair enough--but that raises the question of whether dates should be automatically sorted in Date order. Anyway, I was concerned that I might have found a boundary condition bug. This is something for the backlog I think--ensuring that date data is always in date order, regardless of how it was stored in the source CSV file.

The Date dimension was a time dimension in both versions; in one I didn't specify the format, in the other I did. The first one had klunky plots--I think because only the year was being plotted, or each quarter in a year was stacked vertically--while the latter had smooth plots. The basic point is that I think we should aim to make specifying the date format unnecessary, unless there's a need to clarify when a US MDY format is used and it can't be distinguished from DMY formatted dates. In that case...

I thought it might--in which case, forget the "get me a beta ASAP" in my previous email: this needs to work as well for my intended example file. July 1 is looking like a good choice for the release.

My gawd, you're human after all! 😉. That sounds like one of my mistakes! Good that we've caught this one now, anyway. Can you get a new beta to me ASAP? I want to use this dataset as an indication of getting insights rapidly from Ravel on the Patreon site.

RVL and CSV
-
Here's another example. I aggregated data by sorting and deleting in Excel, so the CSV has the actual numbers that can be compared to what Ravel is pumping out. There are obvious cases of numbers being scambled.
-
I think the redesign of the output from sheets may be the culprit here. The time trend for China in this sheet is the opposite of the data, but the column output for the year 1997 seems to grow as you'd expect China's patents to rise over time.
