QUESTION
I'm trying to create a screener. It starts with plotting:
(a) Two red straight horizontal lines marking the highest high and the lowest low of the lookback period.
(b) Two blue straight horizontal lines marking 25% and 75% points from this range.
Please, check the screenshot.
My issue is: it should mark (plotchar) when ALL the four condition below are met, but it's not working atm.
(1) In the first half of the period, high has been in the upper range at least once.
(2) In the first half of the period, low has been in the lower range at least once.
(3) In the second half of the period, high has been in the upper range at least once.
(4) In the second half of the period, low crosses-under lower the range line.
Unless I'm missing something, all these four conditions are met in the screenshot, therefore it should be char-plotted in candle|4| (when LOW CROSSES-UNDER LOW RANGE LINE), but nothing was plotted.
Any help will be highly appreciated!
Below, the relevant part of the code, but all code is here if you'd like to check and/or re-use.

QUESTION
First: I'm pretty sure this is my poor understanding of how things work 😅
I'm trying to plot a a "solid channel" with two horizontal straight lines as the upper and lower limits (red lines), and two straight horizontal lines that mark the first and the forth "forths" of the range between the upper and lower limits (the blue lines).
I was able to plot them. The problem is: I'd like to have only the last instance of these lines in the screen (based on the lookback period), but most of the time there are many of them.
Below you can see the code. And below the code, you can see in the first screenshot what I expect, and in the second and third screenshots you can see how it usually looks like.
Question is: how can I always have only one instance (the latest one) of this channel in the screen (i.e. only the four expected lines, two red and two blue)?
Any help will be highly appreciated! Cheers!
...ANSWER
Answered 2021-Jan-08 at 21:19You must define your lines once, and then move the instances of the lines with line.set_xy1() and line.set_xy2()

QUESTION
I' am trying to make a program using pygame. The program involves two tiles that switch colours and turn back into their original color once the two tiles have been clicked and after a 1-second delay. My problem is that whenever I tried to implement the pygame.time.delay , it delays the whole system and also affects the scoring mechanism of the program. I tried solving this problem by writing the codes found in handle_color_change and update methods in the game class
Any suggestions to fix this problem is greatly appreciated
...ANSWER
Answered 2020-Nov-29 at 07:52Never use a delay in your application loop. Use the application loop. Compute the point in time when the rectangles have to change color back. Change the color after the current time is greater than the calculated point of time.
In pygame the system time can be obtained by calling pygame.time.get_ticks(), which returns the number of milliseconds since pygame.init() was called. See pygame.time module.
Add 2 attributes self.tile_clicked = 0 and self.turn_white_time = 0 to the class Game:

QUESTION
Project Context
I am working on a VB.Net project that combines a map creator with a database.It is built in line with these tutorials on YouTube (https://www.youtube.com/watch?v=XV2HFzbKOJI&t=195s).
The idea is to be able to click a square on the grid and have the appropriate database row be presented on the screen.
When the user clicks "Go" (see image at the bottom), this records the X and Y grid co-ordinates (see image top right). I accomplish this with the following Click Event:

QUESTION
Whenever I press on one of the buttons created, the procedure that's run does initially change the values of the global variables, but once the procedures finish execution they for some reason revert back. Here's the code:
...ANSWER
Answered 2020-Mar-12 at 10:13You send value from global variable transformEnabled to function but for string/int/float/boolean Python doesn't keep reference to original variable but it copies values to new variable.
You could use global transformEnabled in function and change directly transformEnabled = True to assign value to global variable. But your complex is too code for this simple method.
In your code it is better to keep values in global dictionary and send strings "transform", "selection", "paint" and use them to access data in this global dictionary.
It is big change in code but you need it. Eventually you could try to use classes to create widget which keep buttons and values for one type of functions. You could also use Frame to group buttons and show/hide this frame.
I changed other things in code - based on PEP 8 -- Style Guide for Python Code
