Chart Types Guide

Choose the right visualization for your data story. This guide covers all available chart types and when to use each one.

Bar Chart

Overview

Bar charts display data using rectangular bars with lengths proportional to the values they represent.

Best For

  • Comparing quantities across categories
  • Showing distribution of issues by status, assignee, or type
  • Displaying project metrics side-by-side

Configuration Options

  • Orientation: Horizontal or vertical bars

  • Sorting: By value, alphabetical, or custom order
  • Colors: Individual bar colors or gradient schemes

Example Use Cases

  1. Issue Status Distribution

    • Group by: Status
    • Shows: Number of issues in each status
  2. Team Workload

    • Group by: Assignee
    • Shows: Issue count per team member
  3. Project Comparison

    • Group by: Project
    • Shows: Metrics across multiple projects

Line Chart

Overview

Line charts display data points connected by straight line segments, ideal for showing trends over time.

Best For

  • Tracking changes over time periods
  • Showing velocity trends
  • Monitoring bug discovery/resolution rates
  • Displaying cumulative flow

Configuration Options

  • Line Style: Solid, dashed, or dotted
  • Point Markers: Show/hide data points
  • Smoothing: Apply curve smoothing
  • Multiple Lines: Compare multiple data series
  • Trend Lines: Add linear or polynomial trend lines

Example Use Cases

  1. Sprint Velocity

    • X-axis: Sprint
    • Y-axis: Story points completed
  2. Bug Trend Analysis

    • X-axis: Time period
    • Y-axis: Number of bugs
  3. Cumulative Flow

    • X-axis: Date
    • Y-axis: Cumulative issue count

Pie Chart

Overview

Pie charts show data as slices of a circular graph, with each slice representing a proportion of the whole.

Best For

  • Showing proportions and percentages
  • Displaying distribution of a total
  • Comparing parts to the whole
  • Maximum 5-7 categories for clarity

Configuration Options

  • Slice Labels: Show values, percentages, or both
  • Legend Position: Top, bottom, left, or right
  • Donut Style: Convert to donut chart
  • Exploded Slices: Emphasize specific segments
  • Color Schemes: Categorical or sequential

Example Use Cases

  1. Issue Type Distribution

    • Shows: Percentage of bugs vs. features vs. tasks
  2. Priority Breakdown

    • Shows: Distribution of issues by priority level
  3. Time Allocation

    • Shows: Percentage of time spent on different activities

Area Chart

Overview

Area charts are similar to line charts but with the area below the line filled with color or pattern.

Best For

  • Showing cumulative totals over time
  • Displaying volume changes
  • Comparing multiple data series
  • Emphasizing magnitude of change

Configuration Options

  • Stacking: Normal, stacked, or stream graph
  • Transparency: Adjust fill opacity
  • Gradient Fills: Apply color gradients
  • Baseline: Start from zero or custom value

Example Use Cases

  1. Cumulative Story Points

    • X-axis: Sprint timeline
    • Y-axis: Cumulative points
  2. Resource Utilization

    • X-axis: Time period
    • Y-axis: Hours allocated
  3. Multi-Project Progress

    • Stacked areas for each project

Scatter Chart

Overview

Scatter charts display values for two variables as points on a coordinate system.

Best For

  • Finding correlations between variables
  • Identifying patterns and outliers
  • Analyzing relationships
  • Risk assessment matrices

Configuration Options

  • Point Size: Fixed or variable based on third dimension
  • Point Shape: Circles, squares, triangles, etc.
  • Trend Lines: Linear, polynomial, or logarithmic
  • Quadrants: Divide chart into regions
  • Bubble Mode: Add third dimension via bubble size

Example Use Cases

  1. Effort vs. Value Analysis

    • X-axis: Estimated effort
    • Y-axis: Business value
  2. Bug Complexity

    • X-axis: Time to fix
    • Y-axis: Severity level
  3. Team Performance

    • X-axis: Issues completed
    • Y-axis: Average resolution time

Table View

Overview

Tables display data in rows and columns, providing detailed information in a structured format.

Best For

  • Showing detailed data
  • Providing sortable/filterable views
  • Displaying multiple attributes
  • Exporting data for analysis

Configuration Options

  • Column Selection: Choose which fields to display
  • Sorting: Multi-column sorting capability
  • Filtering: Column-level filters
  • Pagination: Control rows per page
  • Formatting: Conditional formatting rules
  • Totals: Show sum/average rows

Example Use Cases

  1. Issue Details List

    • Columns: Key, Summary, Status, Assignee, Priority
  2. Sprint Report

    • Columns: Issue, Points, Status, Days remaining
  3. Team Metrics

    • Columns: Member, Issues, Points, Avg. resolution

Combination Charts

Overview

Combine multiple chart types to show different data series with appropriate visualizations.

Available Combinations

  • Line + Bar: Trends with volume
  • Area + Line: Cumulative with current
  • Stacked Bar + Line: Distribution with trend

Configuration Options

  • Dual Axes: Different scales for each series
  • Series Assignment: Choose chart type per data series
  • Synchronization: Link interactions between series

Example Use Cases

  1. Burndown with Scope Changes

    • Bars: Scope changes
    • Line: Remaining work
  2. Velocity with Team Size

    • Bars: Story points
    • Line: Team members
