Configuration Options | Matplotlib Configuration | Customization Guide

Matplotlib Configuration

Customize visualization settings in Python code and Matplotlib configuration:

# Matplotlib Configuration (matplotlibrc or Python code) import matplotlib.pyplot as plt import matplotlib # Set default figure size and DPI plt.rcParams['figure.figsize'] = [10, 6] plt.rcParams['figure.dpi'] = 300 plt.rcParams['savefig.dpi'] = 300 # Set style plt.style.use('seaborn-v0_8-darkgrid') # Available styles: 'default', 'seaborn', 'ggplot', 'bmh', 'dark_background' # Customize colors plt.rcParams['axes.prop_cycle'] = plt.cycler('color', ['#3498db', '#27ae60', '#e74c3c', '#f39c12', '#9b59b6']) # Font settings plt.rcParams['font.size'] = 12 plt.rcParams['font.family'] = 'sans-serif' # Export settings plt.rcParams['savefig.bbox'] = 'tight' plt.rcParams['savefig.format'] = 'png'

Configuration Tips:

  • DPI: Set figure DPI for high-resolution exports. Default: 100. Recommended: 300 for publications
  • FIGURE_SIZE: Set default figure size. Example: (10, 6) for width and height in inches
  • STYLE: Use plt.style.use() to apply predefined styles or create custom styles
  • COLORS: Customize color cycle by modifying axes.prop_cycle in rcParams
  • FONTS: Set font family, size, and weight in rcParams for consistent typography
  • EXPORT_FORMAT: Choose PNG, PDF, or SVG format based on your needs

Data Format Requirements

Works with various data formats. Recommended structure for best experience:

# Supported data formats: # - Pandas DataFrame (recommended) # - NumPy arrays # - Python lists # - CSV files (via pd.read_csv()) # Example DataFrame structure: import pandas as pd import numpy as np # Create sample data data = { 'x': np.random.randn(1000), 'y': np.random.randn(1000), 'category': np.random.choice(['A', 'B', 'C'], 1000), 'value': np.random.randn(1000) } df = pd.DataFrame(data) # Works with any DataFrame structure # Numeric columns for plotting # Categorical columns for grouping # Date columns for time series

Customizing Charts

Modify chart configurations in src/plot_utils.py or src/advanced_plots.py:

# Chart customization in Python: import matplotlib.pyplot as plt import numpy as np # Create figure and axes fig, ax = plt.subplots(figsize=(10, 6), dpi=300) # Change colors: ax.plot(x, y, color='#3498db', linewidth=2) ax.bar(x, y, color=['#3498db', '#27ae60', '#e74c3c']) # Modify titles and labels: ax.set_title('Your Custom Title', fontsize=16, fontweight='bold') ax.set_xlabel('X Axis Label', fontsize=12) ax.set_ylabel('Y Axis Label', fontsize=12) # Adjust chart size: fig.set_size_inches(12, 8) # Change colormap: im = ax.imshow(data, cmap='viridis') # For heatmaps scatter = ax.scatter(x, y, c=values, cmap='coolwarm') # Customize grid and spines: ax.grid(True, alpha=0.3, linestyle='--') ax.spines['top'].set_visible(False) ax.spines['right'].set_visible(False)

Adding Custom Charts

Add new visualizations using Matplotlib:

# Add new chart function to src/plot_utils.py or src/advanced_plots.py: def create_custom_chart(data, **kwargs): """Create a custom visualization.""" fig, ax = plt.subplots(figsize=kwargs.get('figsize', (10, 6)), dpi=kwargs.get('dpi', 300)) # Your chart logic here ax.plot(data['x'], data['y'], color=kwargs.get('color', '#3498db'), linewidth=kwargs.get('linewidth', 2), label=kwargs.get('label', 'Data')) # Customize appearance ax.set_title(kwargs.get('title', 'Custom Chart')) ax.legend() ax.grid(True, alpha=0.3) return fig, ax # Use in your code: from src.plot_utils import create_custom_chart fig, ax = create_custom_chart(df, title='My Custom Chart') plt.savefig('output.png', dpi=300, bbox_inches='tight') plt.close()

Detailed Architecture | Dashboard Architecture | System Architecture | Technical Architecture

Dashboard Architecture

1. Streamlit Framework:

  • Built on Python web framework
  • Uses React.js for frontend components
  • Server-side rendering with Python scripts
  • Real-time updates via widget interactions
  • Interactive components (selectboxes, date inputs, buttons, file uploaders)

2. Data Processing Pipeline:

  • Pandas DataFrame for data manipulation
  • CSV file loading and parsing
  • Date parsing and filtering
  • Data aggregation and grouping
  • Real-time filtering based on user selections

3. Visualization Components:

  • Plotly Express for quick chart creation
  • Plotly Graph Objects for advanced customization
  • Interactive charts with hover tooltips
  • Responsive chart sizing
  • Multiple chart types (line, bar, pie, scatter, area, heatmap)

Streamlit Widget System

The dashboard uses Streamlit widgets for real-time updates:

# Streamlit Widget Structure: # Widgets in sidebar or main area region = st.selectbox('Select Region', options=['All', 'North', 'South']) start_date = st.date_input('Start Date', value=datetime(2023, 1, 1)) end_date = st.date_input('End Date', value=datetime(2023, 12, 31)) # Filter data based on widget values filtered_df = filter_data(df, region, start_date, end_date) # Create visualization fig = create_chart(filtered_df) # Display chart (updates automatically when widgets change) st.plotly_chart(fig, use_container_width=True) # Streamlit Flow: # 1. User interacts with widget (selectbox, date_input, etc.) # 2. Script re-runs automatically # 3. Data is filtered and processed # 4. Chart is updated and displayed # 5. Dashboard reflects changes in real-time

Data Filtering Logic

How the dashboard filters data based on user selections:

# Filter Function: def filter_data(region, product, category, start_date, end_date): filtered_df = df.copy() # Apply region filter if region != 'All': filtered_df = filtered_df[filtered_df['Region'] == region] # Apply product filter if product != 'All': filtered_df = filtered_df[filtered_df['Product'] == product] # Apply category filter if category != 'All': filtered_df = filtered_df[filtered_df['Category'] == category] # Apply date range filter filtered_df = filtered_df[ (filtered_df['Date'] >= start_date) & (filtered_df['Date'] <= end_date) ] return filtered_df # All charts and KPIs use the same filtered data # Ensures consistency across all dashboard components

Data Quality Metrics Calculation

How data quality metrics are calculated from filtered data:

# Data Quality Metrics: filtered_df = filter_data(region, product, category, start_date, end_date) # Total Rows and Columns total_rows = len(filtered_df) total_columns = len(filtered_df.columns) # Missing Values missing_count = filtered_df.isnull().sum() missing_percentage = (missing_count / total_rows) * 100 # Duplicate Rows duplicate_count = filtered_df.duplicated().sum() # Column Types numeric_cols = filtered_df.select_dtypes(include=[np.number]).columns.tolist() text_cols = filtered_df.select_dtypes(include=['object']).columns.tolist() date_cols = filtered_df.select_dtypes(include=['datetime']).columns.tolist() # All metrics update automatically when filters change

Chart Types and Usage

Different chart types used in the dashboard:

  • Line Charts: Time series trends using px.line()
  • Bar Charts: Categorical comparisons using px.bar()
  • Pie Charts: Distribution visualization using px.pie()
  • Scatter Plots: Relationship analysis using px.scatter()
  • Area Charts: Cumulative trends using px.area()
  • Heatmaps: Correlation analysis using px.imshow()
  • Box Plots: Distribution and outliers using px.box()
  • Histograms: Frequency distribution using px.histogram()
  • Violin Plots: Distribution comparison using px.violin()
  • 3D Scatter Plots: Multi-dimensional analysis using px.scatter_3d()

Creating Custom Charts

Add new chart types to the dashboard:

# Add custom chart in layout: html.Div([ dcc.Graph(id='custom-chart') ], style={'width': '48%', 'display': 'inline-block', 'margin': '10px'}), # Create callback for custom chart: @app.callback( Output('custom-chart', 'figure'), [Input('region-filter', 'value'), Input('product-filter', 'value'), Input('category-filter', 'value'), Input('date-range', 'start_date'), Input('date-range', 'end_date')] ) def update_custom_chart(region, product, category, start_date, end_date): filtered_df = filter_data(region, product, category, start_date, end_date) # Your custom chart logic # Example: Box plot for revenue distribution fig = px.box(filtered_df, x='Region', y='Revenue', title='Revenue Distribution by Region') fig.update_layout( plot_bgcolor='rgba(0,0,0,0)', paper_bgcolor='rgba(0,0,0,0)' ) return fig

Modifying Data Source

Connect dashboard to different data sources:

# Option 1: Load from database import sqlite3 import pandas as pd def load_data_from_db(): conn = sqlite3.connect('sales.db') df = pd.read_sql_query("SELECT * FROM sales", conn) conn.close() df['Date'] = pd.to_datetime(df['Date']) return df df = load_data_from_db() # Option 2: Load from API import requests def load_data_from_api(): response = requests.get('https://api.example.com/sales') data = response.json() df = pd.DataFrame(data) df['Date'] = pd.to_datetime(df['Date']) return df df = load_data_from_api() # Option 3: Load from Excel df = pd.read_excel('sales_data.xlsx') df['Date'] = pd.to_datetime(df['Date']) # Replace the df loading section in app.py with your data source

Changing Refresh Interval

Modify auto-refresh interval for real-time updates:

# Modify refresh interval in app.py: # Current: 30 seconds (30000 milliseconds) dcc.Interval( id='interval-component', interval=30000, # Change this value n_intervals=0 ) # Examples: # interval=10000 # 10 seconds (more frequent updates) # interval=60000 # 60 seconds (less frequent updates) # interval=5000 # 5 seconds (very frequent, may impact performance) # interval=0 # Disable auto-refresh (manual refresh only) # Or make it configurable in config.py: from config import REFRESH_INTERVAL dcc.Interval( id='interval-component', interval=REFRESH_INTERVAL, n_intervals=0 )

Customizing Chart Colors

Change color schemes for all charts:

# Customize colors in chart callbacks: # Option 1: Use color constants from config.py from config import COLOR_PRIMARY, COLOR_SUCCESS, COLOR_DANGER fig.update_traces(marker_color=COLOR_PRIMARY) # Option 2: Use color scales fig = px.bar(data, x='Region', y='Revenue', color='Revenue', color_continuous_scale='Blues') # or 'Greens', 'Reds', 'Viridis' # Option 3: Custom color mapping color_map = {'North': '#3498db', 'South': '#27ae60', 'East': '#e74c3c', 'West': '#f39c12'} fig.update_traces(marker_color=[color_map[r] for r in data['Region']]) # Option 4: Use Plotly color sequences import plotly.express as px fig.update_layout(colorway=px.colors.qualitative.Set3)

Dataset Information | Data Format | CSV Format | Data Requirements

Data Format Requirements

The dashboard requires CSV format for sales data:

  • Required columns: Date, Region, Product, Category, Quantity, Price, Revenue
  • Date format: YYYY-MM-DD (e.g., 2023-01-01)
  • Numeric columns: Quantity, Price, Revenue must be numeric
  • Text columns: Region, Product, Category are text fields
  • Automatic data loading and parsing
  • Date parsing and validation

Sample Data Format

Your sales data CSV file should follow this structure:

# CSV file structure (sales_data.csv): Date,Region,Product,Category,Quantity,Price,Revenue 2023-01-01,North,Product A,Electronics,100,50.0,5000.0 2023-01-01,South,Product B,Clothing,50,30.0,1500.0 2023-01-02,East,Product C,Food,200,10.0,2000.0 2023-01-02,West,Product D,Books,75,15.0,1125.0 # Column descriptions: # - Date: Sales date (YYYY-MM-DD format) # - Region: Geographic region (text: North, South, East, West, Central) # - Product: Product name (text: Product A, Product B, etc.) # - Category: Product category (text: Electronics, Clothing, Food, Books, Sports) # - Quantity: Number of units sold (numeric) # - Price: Unit price (numeric, decimal) # - Revenue: Total revenue (numeric, can be Quantity * Price or pre-calculated)

Generating Sample Data

Use the included script to generate sample sales data:

# Generate sample data python generate_data.py # The script will: # - Generate sales data from 2023-01-01 to 2024-12-31 # - Create data for 5 regions (North, South, East, West, Central) # - Generate 5 products (Product A through Product E) # - Assign random categories (Electronics, Clothing, Food, Books, Sports) # - Calculate quantity, price, and revenue # - Save to sales_data.csv # Customize data generation: # Edit generate_data.py to modify: # - Date range # - Number of regions # - Number of products # - Categories # - Quantity and price ranges

Using Your Own Data

Replace sample data with your own sales data:

# Steps to use your own data: # 1. Prepare your CSV file # - Ensure all required columns are present # - Date format: YYYY-MM-DD # - Numeric columns: Quantity, Price, Revenue # - Text columns: Region, Product, Category # 2. Replace sales_data.csv # - Backup existing sales_data.csv (if needed) # - Place your CSV file as sales_data.csv # - Or modify DATA_FILE in config.py to point to your file # 3. Verify data format # - Open CSV in Excel or text editor # - Check date format is correct # - Ensure no missing values in required columns # - Verify numeric columns contain numbers only # 4. Run dashboard # - Dashboard will automatically load your data # - All filters and charts will work with your data # - KPIs will calculate based on your data

Troubleshooting & Best Practices | Common Issues | Performance Optimization | Best Practices

Common Issues

  • Port Already in Use: Change port in .streamlit/config.toml (default: 8501). Or stop the process using the port: lsof -ti:8501 | xargs kill
  • Data File Not Found: Ensure sales_data.csv exists or modify DATA_FILE in config.py. Dashboard will generate sample data if file doesn't exist
  • Import Errors: Verify all dependencies installed: pip install -r requirements.txt. Check Python version (3.8+)
  • Date Parsing Errors: Ensure dates are in YYYY-MM-DD format. Check CSV file for invalid date formats
  • Charts Not Updating: Check browser console for JavaScript errors. Verify all callbacks are properly defined
  • Slow Performance: Reduce data size, increase REFRESH_INTERVAL, or optimize data filtering logic
  • Memory Issues: Reduce data size, limit date range, or process data in chunks
  • Export Not Working: Ensure openpyxl is installed for Excel export: pip install openpyxl
  • Search Not Working: Verify search input is connected to filter function. Check callback dependencies
  • Filters Not Applying: Check filter callback functions. Verify filter_data() function is working correctly
  • KPIs Showing Zero: Check if data is loaded correctly. Verify date range includes data
  • Charts Empty: Verify data filtering is working. Check if filtered data has records
  • Dashboard Not Loading: Check if Streamlit is running. Verify port 8501 is accessible. Run: streamlit run app.py
  • CSS Not Loading: Clear browser cache. Check if all CSS files are properly linked
  • Data Table Not Showing: Verify DataTable component is properly imported. Check pagination settings

Performance Optimization Tips

  • Data Size: Limit date range or filter data before loading to reduce memory usage
  • Refresh Interval: Increase REFRESH_INTERVAL for less frequent updates (reduces server load)
  • Chart Optimization: Limit number of data points in charts. Use data aggregation for large datasets
  • Caching: Cache filtered data results to avoid repeated calculations
  • Lazy Loading: Load data only when needed. Use pagination for large datasets
  • Data Preprocessing: Pre-process and aggregate data before loading into dashboard
