Question: Use a factor’s index to plot variables

I’m very new to R so I’m sorry if this is something really simple. I’ve had a look on a bunch of cheat sheets and can’t see anything obvious. I have a simple set of data that has date, temperature, and 4 different factors (based on the bloom of a tree // 1 = “”, […]

Efficient way to create grid based game? (pygame)

Im trying to create a grid-based ecosystem simulation game. The design I came up with is something like a 1000 x 1000 (or larger) grid, with each cell being a representation of an object containing attributes like: soil, moisture, vegetation, temperature, coords, etc which are stored in a 1000*1000 numpy array. These objects should be […]

Multiple axis line chart with Chart.js and JSON data from Google Sheet

I tried to visualize the data, which stored at Google Sheet, with Chart.js in multiple-axis line chart. My data look like this: I tried the following code, but it only showed the first two data (0:00 and 1:00) instead of the whole set data. Also, it has single Y-axis only. May I know what’s wrong […]

IS sensors command from lm-sensos able to find all the internal and external sensor devices?

I am not sure about the detected list of sensor explored with sensors command provided by lm-sensors package. As the wiki of this package said: lm_sensors (Linux monitoring sensors) is a free and open-source application that provides tools and drivers for monitoring temperatures, voltage, and fans. I am a bit doubt about: Does it confined […]

Python TypeError: temperature() missing 1 required positional argument: ‘float’

I just started to learn Python. I tried to create a new function, but the terminal keeps returning the same kind of error. Can you help me figure out what’s going on? TypeError: temperature() missing 1 required positional argument: ‘float’ def temperature(celsius, float) -> float: fahrenheit = (celsius*(9/5)+32) return fahrenheit celsius = float(input(“Input the temperature […]

creating/parsing JSON properly

I have an ESP8266 capable of reading temperature and humidity. The idea is to upload these readings to a Firebase database and once this data is uploaded take some action using Firebase’s function triggers. I have an Arduino code that uploads data from an ESP8622. Data uploaded is a timestamp, sensor id, temperature, and humidity. […]

Curve fitting in Python-Matplotlib

Just would like to address that I am a very beginner programmer with python. Most of my knowledge is what I use/learned for data analysis/plotting for my physics labs. I basically gathered data of capacitance as a function of temperature, and I am supposed to fit the data I plotted with a function to find […]
