lod | lod grading and surface reduction tool SimplyGon | Game Engine library

I know this is probably a basic question, but I'm just getting into GUI building and haven't needed to dabble much in classes for that matter. I have some code (see below) to handle the GUI portion of the program (the CLI version is already running perfectly, but management runs for the hills whenever they see a CLI...), but I can't quite get it to work out. FYI running python 3.9.1 and wxPython 4.1.1 Phoenix (though wx.version also spits out wxWidgets 3.1.5, if that's relevant) on Windows 10

A lot of the code was based around examples / other folks asking stuff here, and unfortunately I can't find the original posts to credit them, but this is really just for learning and once I have a grasp of what I'm doing I'll be writing everything from scratch. So to the original authors, I apologize, but I thank you enormously!

The program is to display a "start" screen (frame), with just a title and single button. On clicking the button, a modal file dialog box opens where the user selects the .csv data file to use, the start frame disappears, and a new frame appears with a view of the data in the right pane (in a grid sizer) and some drop downs and radio buttons in the left pane. The last drop-down (self.inputNum) will be bound to an event handler which will add a number of additional drop-downs for the user to select the different targets to analyze (the number of course being determined by their selection in the self.inputNum combobox). However, when running the script, I get an error

I have two data frames having the same columns with different schema

I've read other answers here, but they all seem to deal with just closing an app altogether, making sure all processes and frames and such are destroyed in the process. What I want to do is a little different.

My app consists of three frames (StartFrame, ParaFrame, ResultFrame) as well as a custom class for storing and manipulating data. The basics are: StartFrame is just some text and a "start" button. "Start" creates an instance of ParaFrame, hides the StartFrame, and shows the ParaFrame instance. Paraframe has a bunch of widgets for the user to select a file and how to analyze it. When all the fields are entered, an "Analyze" button pops up, which (when clicked) instantiates the custom DataHandler class, sets its parameters according to the user selections, calls a DataHandler method which analyzes the data, hides itself, and instantiates+shows the ResultsFrame. Not surprisingly, the ResultsFrame shows the results of the analysis.

I want to add a "Start Over" control which will destroy everything (all the frames, panels, the DataHandler instance, etc.) and display a fresh StartFrame instance, or otherwise destroy everything except the already-instantiated-but-hidden StartFrame, showing that frame again, but I'm at a loss.

A simplified example follows:

For an academy project I have to find parts of a object (location / angle relative to the object ). The object is marked with a QR-code.

Currently I'm stuck on the basics. I scanned a room and load this room with "Spatial Object Mesh Observer".

But this observer gives no relevant information: The observer does not attempt to find 3D model LODs when sending the meshes to the application.

Someone a hint where I could start?

I have a strange feeling I'm doing something wrong here.

This is my PowerShell script, of course stolen and adapted from here:

I've got a script wherein I have two functions, makeplots() which makes a figure of blank subplots arranged in a particular way (depending on the number of subplots to be drawn), and drawplots() which is called later, drawing the plots (obviously). The functions are posted below.

The script does some analysis of data for a given number of 'targets' (which can number anywhere from one to nine) and creates plots of the linear regression for each target. When there are multiple targets, this works great. But when there's a single target (i.e. a single 'subplot' in the figure), the Y-axis label overlaps the axis itself (this does not happen when there are multiple targets).

Ideally, each subplot would be square, no labels would overlap, and it would work the same for one target as for multiple targets. But when I tried to decrease the size of the y-axis label and shift it over a bit, it appears that the actual axes object was drawn over the previously blank, square plot (whose axes ranged from 0 to 1), and the old tick mark labels are still visible. I'd like to have those old tick marks removed when calling drawplots(). I've tried changing the subplot_kw={} arguments in makeplots, as well as removing ax.set_aspect('auto') from drawplots, both to no avail. Note that there are also screenshots of various behaviors at the end, also.

I have a quick question. I'm trying to grab user ids based on their 1st purchase and products selected:

I have a fairly lengthy program that I've been working on to do some data analysis at my lab. It takes a csv file and calculates a limit of detection for one or more gene targets based on a range of concentrations of input DNA (RNA, actually, but it's irrelevant in this case).

Since the number of targets to be evaluated is variable, I wrote two functions - one makeplots(targets) that returns a figure with subplots (arranged how I want them, depending on how many there are) and the array of axes for the subplots. After some data processing and calculations, my drawplots(ax[i], x, y, [other variables for less-relevant settings]) function is called within a loop that's iterating over the array of data tables for each target.

makeplots() works fine - everything's where I want it, shaped nicely, etc etc. But as soon as drawplots() gets called, the scales get warped and the plots look awful.

The code below is not the original script (though the functions are the same) -- I cut out most of the processing and input steps and just defined the variables and arrays as they end up when working with some test data. This is only for two targets; I haven't tried with 3+ yet as I want to get the simpler case in order first.

(Forgive the lengthy import block; I just copied it from the real script. I'm a bit pressed for time and didn't want to fiddle with the imports in case I deleted one that I actually still needed in this compressed example)

In Google Data Studio I have a small table including a dimension and a metric

Is there a way to calculate the total sum across the dimension (like an LOD) which is shown as an additional column next to the user? The solution should look like this
