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

Here is the UI file looks like:

The imageview is above the textview.

Here is what my output looks like:

Not sure. I commented out the line, but it still does not load for me.

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.

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)

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 = [0]
	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 = [0]
	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.
