Combined EChart

A Combined EChart displays multiple chart types—such as column, line, and area—in a single visual, making it easier to compare datasets with different units or magnitudes.

Key Features

• Multiple Chart Types: Combine different series types in one chart.

• Shared X-Axis: All series share the same category-based X-axis.

• Dual Y-Axes: Assign series to either the left or right Y-axis based on their value ranges.

• Flexible Styling: Customize chart type, axis assignment, and appearance per series.

• Labels and Tooltips: Add data labels and enable tooltips to display exact values on hover.

When to Use

Use a Combined EChart to:

• Show different metrics (e.g., revenue vs. margin) together.

• Compare trends using varying scales.

• Highlight relationships across multiple datasets.

Example

A Combined EChart might show monthly revenue (column) alongside profit margin (line) on a secondary Y-axis to compare financial performance over time.

Customization Options

You can customize the following for each series:

• Chart Type: Choose column, line, or area.

• Y-Axis: Assign to left or right axis depending on the value range.

• Color and Style: Adjust series color, line thickness, or column width.

• Data Labels: Toggle on/off and format as needed.

Formatting Tips

• Use contrasting colors to differentiate series types.

• Use the right Y-axis for metrics with significantly different scales.

• Keep the chart readable by limiting the number of series.
