There is a way to use pandas via sagecell -- essentially you run your code via cloud.

See the entire thread here:

Pythonista comes with numpy and matplotlib, but not pandas or scipy. There are now apparently a few ios apps that do support pandas, but most of these have poor interfaces.

No, it is not supported. You can only install pure python modules

You could also set the imageview transform to ui.Transform.rotation(90), depending on what you are trying to do.

I find it is helpful to use developer tools on your desktop (F12 on chrome or IE/edge, I suspect safari has something similar), then select the element, and check the XPath.

Sometimes, sites may have elements populated via JavaScript, dynamically. In that case, you need to use a webview. @michael's wkwebview wrapper should let you do this easily.

Looking at setup.py:

install_requires =
    requests[security]
    numpy
    scipy
    matplotlib
    pandas
    pillow
    pyglet
    pyopengl
    soundfile
    sounddevice
    python-bidi
    arabic_reshaper
    cffi
    future
    json_tricks
    pyosf
    xlrd
    openpyxl
    pyserial
    pyyaml
    gevent
    msgpack-numpy
    msgpack-python
    psutil
    tables
    pyzmq
    moviepy
    opencv-python
    python-gitlab
    gitpython
    astunparse
    esprima
    freetype-py
    # Platform-specific dependencies.
    imageio < 2.5; python_version < "3"
    imageio >= 2.5; python_version >= "3"
    imageio-ffmpeg; python_version >= "3"
    pyparallel; platform_system == "Linux"
    pyWinhook; platform_system == "Windows"
    pyqmix >= 2018.12.13; platform_system == "Windows"
    pyqt5; python_version >= "3"
    wxPython != 4.0.2, != 4.0.3; platform_system != "Linux"
    pypiwin32; platform_system == "Windows"
    pyobjc-core; platform_system == "Darwin"
    pyobjc-framework-Quartz; 

A good fraction of these are incompatible with pythonista. For instance scipy.

@upwart so you are combining many PIL images into a single SpriteNode because thousands of spritenodes have a performance penalty?

Are all of the subimages continuously changing? Are these mini plots of some sort, or status icons? In other words is there a lot of repeated content? (Can you post a screenshot?)

There may be some low level ways to get from something like an io surface into a texture. Or, there may be ways to create your ui.Images or scene.Textures such that the PIL image can write directly into the buffer, which minimizes the amount of conversions needed.

If you are trying to make reusable classes, you could consider using a delegate attribute, or menu items are defined with a title, target object and a method that gets called on the target. That way a menu can target the root, or target some low level component.

How are you generating the image?

See https://forum.omz-software.com/topic/5155/real-time-audio-buffer-synth-real-time-image-smudge-tool

This has the fastest methods to update images although in a ui.View. you can get 60 fps or higher with a recent device.

Not sure if this would work with scene.

What device are you using? Are you using an external kb?

Check the settings for second row, under the gear icon in the file menu, then keyboard.

Search shadertoy for reaction diffusion, and see if there is one that does what you want. For the most part, I think the stuff you can find on shadertoy should work with minimal work in pythonista.
