Update:

There are too many screenshots, and some are outdated. Update screenshots.

Feature Request:

Many European countries use a mirrored version of the psychrometric chart, with temperature on y-axis, absolute humidity on x-axis, and obviously SI units. We call it "Mollier-hx-Diagramm". The content is the same.
Example Wikipedia
It would be a super feature if it was possible to chose this "European version".
The plugin right now is awesome, but unfortunately not much of a help in my country as this sort of diagram is unknown.

Hi @yevgeny7 and thanks for your request! I don't think this type of chart is as common in the United States, but I am familiar with it and think it would be a great addition for Psychart. I'll keep you updated when I am able to work on this.

@yevgeny7 I'm working on cleaning things up and fixing some issues in version 4.2.x. I'd like to introduce within one of the next 2 following minor versions, either 4.3.x or 4.4.x. I'm hoping to get to that point within the next few weeks, and I'll let you know when it's actively in development!

[yevgeny7]

@6nv Sounds great. I'm happy to help with some testing and feedback.

Thanks for your patience. So realizing that a Mollier diagram is essentially a Psychrometric Chart (or Carrier Diagram, according to the Wikipedia article!) mirrored on x=y, what I'm doing here is adding an additional option to flip X and Y.

Here's a screenshot of the final product. This might not be exactly what you're looking for, but it leverages a lot of the existing logic and code to make what I think is a rather elegant solution. I'm still working on cleaning it up and I hope to push it live in the next week or so. Is this something that you think will be useful for you?

@6nv Oh that looks already pretty familiar, flipping is already the most important move. Nice!
I have noticed, in the options you can select SI units, which is really great.

A few more changes should make it really useful to broader range of users:

no. 1 (prio 1): As vertical lines, with units on top, the EU version shows the absolute humidity (0 g/kg ... 20 g/kg) instead of the wet bulb temp (e.g. 90 °F) in the flipped psychart.

no 2 (prio 3): As diagonal lines, with units along at the wet bulb curve, the EU version shows the enthalpy (0 kJ/kg ... 60 kJ/kg) instead of the the wet bulb temp (20 °F ... 90 °F).

no. 3 (prio 1): data: as raw data we usually have dry bulb in °C and relative humidity (%). that would be rather helpful to use these values directly as input, and avoid additional pre calculation from °C to °F.

no. 4 (prio 2): comfort regions/envelope: of course we have other envelopes than included. I don't think you need to set EU envelopes, or any other, precoded by you. Because there is just too many. It would be a very powerful feature if the user could set individual envelopes by putting in the boundary conditions. An envelope consists of 4 to 6 corner points and the connection between them, straight connection or along some static value like relative humidity.

Sorry if it is a lot too ask. :-)

@yevgeny7 - good news, your item (no. 3) is already a feature! If your data is in Celsius, simply toggle this option. No unit conversion needed:

Your item (no. 4) might also exist already if I understand it correctly. When you switch from US to SI units, the regions will re-calculate in the proper unit. If there are additional envelopes you would like to see added in Psychart, please let me know! That is easy to implement.

As for items (no. 1) and (no. 2), that would fundamentally change how I build and render Psychart and would be a long term project. However, there exists a feature that you may be interested in, to show "advanced" state variables. When enabled, you can hover over a point to see absolute humidity (called Hum. Ratio) and enthalpy. Of course, these numbers will be calculated in SI units when selected.

Let me know if these features help you achieve your goal!

@yevgeny7 - Psychart v4.3.0 is available for installation.
