Data Visualization: Key Queries Explained

1.What is a Mekko chart good for?   

A Mekko chart, also known as a Marimekko chart, is useful for visualizing categorical data across two dimensions. It effectively displays market share, revenue distribution, or performance metrics, allowing for easy comparison of different categories and their sizes. The variable-width columns and variable-height bars help identify trends and relationships within complex datasets immediately.

2. How to create a mekko chart?

To create a mekko chart, gather your data and categorize it into two dimensions (e.g., market size and market share). Use spreadsheet software like Excel to create a stacked bar chart, adjusting the widths of the bars to represent one dimension and the height to represent the other. Label axes and add data labels for clarity.

3. How do I edit a Mekko chart?

To edit a Mekko chart, use chart editing software like Excel or specialized tools. Click on the chart to select it, then modify data in the source table, adjust chart elements (like titles and labels), or change formatting options. You can also add or remove series and categories as needed to reflect the desired information accurately.

4. How do you add a title to a chart in Mekko?

To add a title to a chart in Mekko, select the chart, then look for the title option in the chart settings or properties panel. Enter your desired title in the provided text box and adjust font size or style as needed. Save your chances to apply the title to the chart.

5. What is Mekko chart and what is the difference between bar and Mekko chart?

A Mekko chart, or Marimekko chart, visually represents categorical data with varying widths and heights, showing both category size and value. Unlike bar charts that have uniform widths, Mekko charts combine bar height and width to convey two dimensions of data simultaneously, making them more effective for comparing market share or product performance across multiple categories.

Subtotals enhance understanding of the data by breaking down complex information into digestible segments.

5. How to analyse a waterfall chart?

To analyze a waterfall chart, start by identifying the initial value at the left. Observe how each subsequent bar represents increases or decreases, leading to the final value on the right. Assess the contributions of each segment to understand the overall trend and key drivers. Look for patterns, significant changes, and outliers to derive insights on performance or variations in data.
