Welcome to pygameChart! This package provides a simple and flexible way to create charts and plots within a pygame application. With pygameChart, you can easily visualize data and display in your applications in an appealing way. Its structure to define figure parameters and charts is similar to matplotlib for ease of use.
Package in PyPI repository under pygame-chart.
pip install pygame-chart
Please consider project page on Github, https://github.com/enessafak/pygame-chart. The module requires python>=3.9.10 and pygame>=2.1.2
pygameChart provides a simple use (similar to matplotlib) to create figure, set properties (like title, label names, chart limits etc.) and add several charts. In this phase it supports line plot, scatter plot and bar charts. Also in this phase, it accepts x and y axis data as two separate lists. I will add support for accepting different datatypes like dictionary numpy arrays or pandas series and dataframes.
Basic use of the package creates following result.
import pygame, sys
import pygame_chart as pyc
# pygame app for figure to run
pygame.init()
screen = pygame.display.set_mode((800,600))
# Figure instance on screen with position and size
figure = pyc.Figure(screen, 50, 50, 700, 500)
while True:
events = pygame.event.get()
for event in events:
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
# add a line chart. First argument "name" should be unique for every chart
figure.line('Chart1', [1,2,3,4,6,20,24],[3,5,7,2,7,9,1])
# draw figure with specified properties
figure.draw()
pygame.display.update()
import pygame, sys
import pygame_chart as pyc
# pygame app for figure to run
pygame.init()
screen = pygame.display.set_mode((800,600))
# Figure instance on screen with position and size
figure = pyc.Figure(screen, 50, 50, 700, 500)
while True:
events = pygame.event.get()
for event in events:
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
# Add chart title with a title
figure.add_title('pygameChart Example')
# Add legend and gridlimes
figure.add_legend()
figure.add_gridlines()
# add a line chart. First argument "name" should be unique for every chart
figure.line('LineChart', [1,2,3,4,6,20,24],[3,5,7,2,7,9,1])
figure.bar('BarChart', [1,2,3,4,10,18,24],[4,3,9,2,7,12,5])
figure.scatter('ScatterChart', [-4,3,6,8,12,16,20],[2,4,12,5,6,3,8])
# draw figure with specified properties
figure.draw()
pygame.display.update()
This documentation provides classes in pygameChart with relative methods and attributes. Default values for initiations are given as global variables and can be modified in settings.py. Only class the end user should use is Figure class. For the rest, only relevant method or attributes will be mentioned.
pygameChart.Figure(screen, x, y, width, height, bg_color=BG_COLOR)
Parameter | Type | Explanation |
---|---|---|
screen | pygame.display | Main display for figure to be drawn |
x | number | Position of figure at x axis |
y | number | Position of figure at y axis |
width | number | Width of the figure |
height | number | Height of the figure |
bg_color | RGB tuple (r,g,b) | Background color of the figure |
Base object for figure areas: title, legend, x-y axis labels, x-y axis ticks and chart area
pygameChart.Area(figure)
Attribute | Type | Explanation |
---|---|---|
figure | pygame.Chart.Figure | Main Figure object |
x | number | Position of area at x axis (rel. to figure) |
y | number | Position of area at y axis (rel. to figure) |
width | number | Width of the area |
height | number | Height of the area |
innerx | number | Inner x position for padding |
innery | number | Inner x position for padding |
innerwidth | number | Inner width for padding |
innerheight | number | Inner height for padding |
show | boolean | draw condition for the area |
Class for adding and writing chart title
Class for calculating legend position, content and writing
Class for adding and writing y-axis label
Class for adding and writing x-axis label
Class for calculating x-tick position, content and writing
Attribute | Type | Explanation |
---|---|---|
ymin | number | Min value for y-ticks. Might be different than chart data. Overwritten by Figure.ylim |
ymax | number | Min value for y-ticks. Might be different than chart data. Overwritten by Figure.ylim |
Class for calculating y-tick position, content and writing
Attribute | Type | Explanation |
---|---|---|
xmin | number | Min value for xx-ticks. Might be different than chart data. Overwritten by Figure.xlim |
xmax | number | Min value for x-ticks. Might be different than chart data. Overwritten by Figure.xlim |
Class for calculating chart positioning and drawing
Attribute | Type | Explanation |
---|---|---|
charts | list | List of chart objects added to the figure |
chart_names | list | List of chart names added to the figure |
chart_margin | int | Padding for left and right border |
xdata_type | str | Indicates the type of xdata (number or string). If figure.xlim is set, it becomes number. Otherwise, it is determined by the first chart to be added. Charts with other type of xdata cannot be added later |
gridlines | boolean | If gridlines will be added to the figure |
Base class for all chart types
Class for keeping properties of line chart. Drawing is done within Figure.ChartArea
Parameter | Type | Explanation |
---|---|---|
name | string | Name of the chart |
xdata | list | x-axis data. List must be all numbers or all strings |
ydata | list | y-axis data. List must be all numbers |
color | tuple | RGB tuple (r,g,b). Default value chooses the next unused color from settings.py |
