  5. Drag the same measure to the Rows shelf again.
  6. Change the second measure to a “Gantt Bar” chart type.
  7. In the “Marks” card, change the second measure’s “Color” to “White”.
  8. In the “Analysis” menu, select “Stack Marks” > “Off”.
  9. Adjust the size of the Gantt bars to create the desired size and spacing for your waterfall chart.
  10. Customize the chart as desired by adding labels, formatting, and other design elements.

By following these steps, you should be able to create a waterfall chart in Tableau that effectively illustrates the changes in your data over time.

What are Gantt Charts and how to draw them in Tableau.

A Gantt chart is a type of bar chart that is commonly used in project management to illustrate a project schedule. It shows the start and end dates of each task or activity, as well as their duration and the dependencies between them. The chart is named after its inventor, Henry Gantt, who developed it in the early 20th century.

In Tableau, you can create a Gantt chart by following these steps:

  1. Connect to your data source and open a new worksheet.
  2. Drag the dimension that represents the tasks or activities to the Rows shelf.
  3. Drag the start date and end date dimensions to the Columns shelf. You can use the “Exact Date” data type for both dimensions to ensure that the chart displays the dates correctly.
  4. Change the mark type to Gantt Bar by selecting it from the “Marks” card.
  5. Adjust the colors, sizes, and labels of the bars and add any additional information or formatting as needed.

You can also add dependencies between tasks by creating a separate data source or a calculated field that specifies the order in which tasks must be completed. Then, you can use the “Dual Axis” feature in Tableau to display the dependencies as arrows or lines connecting the tasks.

What are Box-and-Whisker Plots and how to draw them in Tableau.

Box-and-Whisker Plots, also known as Box Plots, are a type of chart used to display the distribution of a dataset. They are useful for showing the range, median, and quartiles of a dataset, as well as any outliers or extreme values.

To create a Box-and-Whisker Plot in Tableau, follow these steps:

  1. Drag the dimension or measure you want to analyze to the Rows or Columns shelf.
  2. Click on the drop-down menu next to the dimension or measure and select “Box Plot”.
  3. You should now see a box-and-whisker plot displaying the median, quartiles, and any outliers in your data.

You can also customize your Box-and-Whisker Plot in Tableau by adjusting various settings, such as changing the colors, adding reference lines, or showing/hiding different elements of the plot. To do this, use the “Marks” card and the “Analysis” menu in the toolbar.

What are Histograms and how to draw them in Tableau.

Histograms are charts that display the distribution of a continuous variable. They consist of a series of bars, where the height of each bar represents the frequency or count of data values falling within a certain range or bin. Histograms are commonly used in data analysis to identify patterns or outliers in data sets.

To create a histogram in Tableau, follow these steps:

  1. Connect to your data source and drag the desired continuous variable to the Rows or Columns shelf.
  2. On the Marks card, change the chart type to Histogram.
  3. Adjust the bin size to control the width of the bars and the number of bins displayed. Tableau will automatically set a default bin size, but you can change it by right-clicking on the axis and selecting Edit.
  4. Add any additional dimensions or measures to the view to further segment or filter the data.
  5. Customize the chart as desired by adjusting colors, labels, and formatting.

Once you have created a histogram in Tableau, you can use it to explore the distribution of your data and identify any interesting patterns or trends.

What are Pareto Charts and how to draw them in Tableau.

Pareto chart is a type of chart that combines both bar and line graphs, which is used to display the relative importance of various categories or factors. It is based on the Pareto principle which states that a small number of causes or factors can be responsible for a large percentage of the effects.

To create a Pareto chart in Tableau, follow these steps:

  1. Connect to your data source and create a new worksheet in Tableau.
  2. Drag the dimension that you want to use for your categories onto the Columns shelf.
  3. Drag the measure that you want to use for your values onto the Rows shelf.
  4. Right-click on the measure on the Rows shelf and select “Add Table Calculation.”
  5. In the “Table Calculation” dialog box, select “Percent of Total” as the calculation type.
  6. Drag the same measure onto the Rows shelf a second time.
  7. Change the mark type for the second measure to a line graph.
  8. Right-click on the second measure on the Rows shelf and select “Dual Axis” to combine the two graphs.
  9. Right-click on the second axis and select “Synchronize Axis.”
  10. Finally, you can format your chart by adjusting the colors, fonts, and other visual elements as per your preference.

Once you have created the Pareto chart in Tableau, you can use it to identify the most significant factors or categories that contribute to a particular outcome or problem.

What are Pie Charts and how to draw them in Tableau.

Pie charts are circular charts that represent data as slices of a pie or donut. Each slice represents a proportion of the whole, and the size of the slice corresponds to the relative size of the proportion. Pie charts are useful for visualizing the distribution of a categorical variable, such as the proportion of sales by product or the percentage of website traffic by source.

To create a pie chart in Tableau:

  1. Connect to your data source and drag the categorical variable you want to use to the Rows or Columns shelf.
  2. Drag the measure you want to visualize to the Marks card.
  3. Change the Mark type to Pie chart by clicking on the drop-down menu on the Marks card and selecting “Pie”.
  4. You can customize the appearance of your pie chart by adjusting the size, colors, and labels using the formatting options in the Marks card, the Show Me panel, or the Format menu.

It is important to note that pie charts can be difficult to read accurately for more than a few categories, and it may be more effective to use a different chart type, such as a bar chart, for larger datasets.
