    Study Notes

    Creating Scatter Plots

    • Scatter plots are created by placing measures on the Columns and Rows shelves in Tableau.
    • Measures are always placed to the right of any dimensions on these shelves.
    • Scatter plots can use different mark types like circle, square, and shape.

    Creating a Scatter Plot with Sales and Profit

    • Drag the Profit measure onto the Columns shelf.
    • Drag the Sales measure onto the Rows shelf.
    • This creates a scatter plot with Sales on the Y-axis and Profit on the X-axis.
    • Drag the Category dimension onto the Color mark to create separate marks for each category and differentiate them by color.
    • Drag the Region dimension onto the Detail mark to show multiple marks for each region.

    Heatmaps

    • Heatmaps are scatter plots that use color to show data distribution or relationships.
    • They are useful for highlighting patterns and correlations between categories, especially in large datasets.
    • To create a Heatmap, drag dimensions to the Columns and Rows shelves and a measure to the Color mark.

    Box Plots

    • Box plots are used to visually summarize data distribution, identify outliers, and show data spread.
    • They also enable comparison of multiple datasets side-by-side.
    • Components of a box plot include Minimum, Lower Quartile (Q1), Median (Q2), Upper Quartile (Q3), and Maximum.

    Line Graphs

    • Line graphs are useful for visualizing trends and changes over time, such as sales over years or website traffic over months.
    • To create a line graph, drag a date field to the Columns shelf and a measure to the Rows shelf.

    Pie Charts

    • Pie charts are used to show proportions or percentages of a whole, representing how different categories contribute to a total.
    • They are best for visualizing relative proportions with a few categories.
    • To create a pie chart, drag a dimension to the Columns shelf, a measure to the Rows shelf, and select the Pie Chart option from the Marks menu.

    Scatter Plots for Relationships

    • Scatter plots are used to show the relationship or correlation between two variables.
    • They help identify positive, negative, or no correlation by visually representing the relationship between the variables.
    • To create a scatter plot for relationships, drag one measure to the Columns shelf, another measure to the Rows shelf, change the Marks type to Circle, and drag a dimension to Color for differentiation.
