18. a) Charts Part 1: Bar, line, Combo, Pi, Scatter, Box Plot in Qlik Sense

Introduction

This tutorial will guide you through creating various chart types in Qlik Sense, including bar charts, line charts, combo charts, and box plots. Understanding how to use these charts effectively will help you visualize data trends and comparisons, making your analysis more impactful.

Step 1: Creating a Bar Chart

Bar charts are effective for displaying one or more measures against a single dimension. Here’s how to create one:

1. Select Data: Choose the measure(s) and dimension.

   • Example Measures: Actual vs. Budget
   • Example Dimension: Quarter

2. Visualize Data:

   • Use the bar chart to compare values such as the sum or average of runs for each player.

3. Practical Tip: Ensure your data is clean and well-organized to avoid misleading representations.

Step 2: Creating a Line Chart

Line charts are ideal for showing trends over time. Follow these steps:

1. Select Trending Data: Choose a measure that represents data moving over time.

   • Example Measure: Sum of Sales
   • Example Dimension: Months

2. Visualize Trends:

   • Use the line chart to track performance trends, such as monthly sales figures.

3. Two-Dimensional Comparisons:

   • You can compare two dimensions, like annual sales over each month.

4. Common Pitfall: Avoid overcrowding your chart with too many lines, which can confuse the viewer.

Step 3: Creating a Combo Chart

Combo charts allow for the comparison of multiple measurements in a single visualization. Here’s how to create one:

1. Select Measurements: Choose the different measures to compare.

   • Example Measures: Average Sales and Average Budget

2. Set Time Frame: Define the dimension for your time frame, such as by year.

3. Practical Tip: Ensure each measure has a distinct visual style (like different colors or markers) for clarity.

Step 4: Creating a Box Plot

Box plots are useful for comparing the distribution and range of groups within numerical data. To create one:

1. Select Data Groups: Choose the groups you want to compare.

2. Visualize Distribution:

   • The box plot will display the median, quartiles, and potential outliers in your data.

3. Practical Tip: Use box plots when you want to highlight differences in data distribution rather than just averages.

Conclusion

In this tutorial, you learned how to create several essential chart types in Qlik Sense, including bar charts, line charts, combo charts, and box plots. Each chart serves a specific purpose, helping you to analyze and present data effectively. Start applying these techniques to enhance your data visualization skills and make your analyses more compelling. For further learning, explore additional resources and practice with real datasets.
