It works, thanks. Do you know why I needed to restart the app?

RE: Load Image from URL
The documentation said that by leaving it blank it will default to the same file name but with 'pyui'. The UI portion will load, and the text appears. However, the imageview is blank. I just took what worked with the text (page_text = v['textview1']) and tried it for the image. I assume the problem is there, but I am not sure what it is.
Load Image from URL
I am making a dumb little program to learn how to use Pythonista. I am trying to something that changes the text/image when you tap the forward or back buttons. I cannot get the image to view. Does anybody see what I am doing wrong? Thanks.
import ui page_count = 1 # text for each page page1_text = 'This app introduces the game of baseball.\nUse the navigtion arrows to change pages.' page2_text = 'Page 2' page3_text = 'Page 3' # images for each page page1_img = 'http://www.talmageboston.com/files/2016/04/Baseball-Grass.jpg' def update_page(page_text, page_img): if page_count == 1: page_text.text = page1_text page_img.load_from_url(page1_img) v = ui.load_view() page_text = v['textview1'] page_img = v['imageview1'] v.present('sheet') while True: update_page(page_text, page_img)
UI for matplotlib
I new to Python/Pythonista, and I am wondering if it would be possible to have a UI to launch something I did in matplotlib. I want to be able to tap a button and launch the scatter plot. The scatter plot works without the UI, but I am having trouble getting the button to work. Here is the code I have so far:
import ui import matplotlib.pyplot as plt from random import choice, randint v = ui.load_view() v.present('sheet') def button_tapped(sender): show_walk() def fill_x_values(walk_length): x_values =  points = walk_length while len(x_values) < points: x_direction = choice([1, -1]) x_distance = choice([1, 2, 3, 4]) x_step = x_direction * x_distance next_x = x_values[-1] + x_step x_values.append(next_x) return x_values def fill_y_values(walk_length): y_values =  points = walk_length while len(y_values) < points: y_direction = choice([1, -1]) y_distance = choice([1, 2, 3, 4]) y_step = y_direction * y_distance next_y = y_values[-1] + y_step y_values.append(next_y) return y_values def show_walk(): walk_length = 50000 x_values = fill_x_values(walk_length) y_values = fill_x_values(walk_length) plt.scatter(x_values, y_values,c='red', edgecolor='none', alpha=0.2, s=7) plt.axes().get_xaxis().set_visible(False) plt.axes().get_yaxis().set_visible(False) plt.show() button = ui.Button() button.action = button_tapped
Do any of you see what I am doing wrong? If you need any more info from me, please let me know. Thanks in advance.
