Chart Types Guide

​

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

​

Choosing the Right Chart
