 Explain z-order in Power BI ?

Z-order, or Z ordering, in Power BI refers to the front-to-back layering of visuals in a report. It essentially determines which visuals overlap and which ones are visible on top. Understanding and effectively utilizing Z-order can enhance the clarity and impact of your Power BI reports.

Here's a breakdown of the concept:

Purpose:

• Z-order allows you to control the visual stacking of elements in your report. This facilitates:

• Avoiding visual clutter: Overlapping visuals can be confusing and hinder data communication. By adjusting Z-order, you can ensure crucial information stands out.

• Creating depth and emphasis: Strategically layering visuals can add visual interest and guide viewers' attention to specific elements.

• Building custom visuals: You can combine multiple visuals with different Z-order settings to create custom and complex visualizations.

Setting Z-order:

• There isn't a dedicated "Z-order" button in Power BI. You can adjust the layering in two ways:

• Selection pane: Select the desired visuals in the "Selection" pane. Right-click and choose "Move forward" or "Move backward" to change their positions in the stack.

• Drag and drop: Drag and drop visuals on the report canvas to manually place them above or below each other.

Considerations:

• Z-order applies to all types of visuals, including charts, graphs, shapes, and images.

• Remember that visuals behind others will be partially or completely obscured.

• Use Z-order thoughtfully to avoid distracting or confusing viewers with unnecessary layering.

• Test and refine your Z-order settings to ensure optimal clarity and visual hierarchy in your report.
