Why combine chart types in a dashboard?

Which reason best explains why combining different chart types in a Tableau dashboard helps tell a richer story?

A It reduces the amount of data needed to create the dashboard.

B It allows showing multiple data perspectives together, making insights clearer.

C It makes the dashboard load faster by using simpler charts.

D It limits user interaction to only one chart at a time.

💡 Hint

Think about how different charts can show different parts of the data story.

Combining chart types lets you display various aspects of data side by side, helping users understand complex information more easily.

Identify the best chart combination for sales and profit analysis

You want to show total sales over time and profit margin percentage in one dashboard. Which combination of chart types is best?

A Histogram for sales over time and area chart for profit margin percentage.

B Line chart for sales over time and bar chart for profit margin percentage.

C Pie chart for sales over time and scatter plot for profit margin percentage.

D Bar chart for sales over time and line chart for profit margin percentage.

💡 Hint

Think about which chart type best shows trends over time and which best compares percentages.

A line chart is ideal for showing trends over time, while a bar chart clearly compares profit margin percentages across categories or periods.

Calculate total sales per region with fixed level of detail

Given a sales dataset with columns Region, Sales, and Date, which Tableau LOD expression correctly calculates total sales per region regardless of filters?

Tableau

{FIXED [Region] : SUM([Sales])}

A {FIXED [Region] : SUM([Sales])}

B {INCLUDE [Region] : SUM([Sales])}

C {EXCLUDE [Region] : SUM([Sales])}

D SUM({FIXED [Region] : [Sales]})

💡 Hint

Remember that FIXED ignores filters except context filters and fixes calculation at the specified dimension.

The FIXED LOD expression calculates total sales per region regardless of other filters, which is useful for combining with other chart types to show consistent regional totals.

Choosing chart types to highlight sales and customer satisfaction

You have sales data and customer satisfaction scores by product category. You want to show sales volume and satisfaction side by side to find patterns. Which chart combination best supports this goal?

A Scatter plot with sales volume on X-axis and satisfaction on Y-axis.

B Histogram for sales volume and area chart for customer satisfaction.

C Stacked bar chart for sales volume and heat map for customer satisfaction.

D Pie chart for sales volume and line chart for customer satisfaction over time.

💡 Hint

Think about which chart type best shows relationships between two variables.

A scatter plot shows the relationship between sales volume and customer satisfaction clearly, helping identify patterns or correlations.

Identify the error in combining dual-axis charts in Tableau

In Tableau, you create a dual-axis chart combining a bar chart and a line chart. The line chart does not align properly with the bar chart. What is the most likely cause?

A The dashboard layout does not support dual-axis charts.

B The data source is missing a join between the two measures.

C The axes are not synchronized, causing misalignment between the two charts.

D The bar chart uses a continuous axis while the line chart uses a discrete axis.

💡 Hint

Check if the scales of both axes match in dual-axis charts.

Dual-axis charts require synchronized axes to align properly. If axes are not synchronized, the two charts will not line up correctly.
