ISM Week 9 Scav
Including how to connect to a specific worksheet within that Excel file
Add new data source (little arrow next to the cyclinder thing)
Making the pie chart bigger
Can CTRL-SHIFT-B to make it larger incrementally
Understand why Tableau sometimes miscategorizes dimensions as measures... and how to fix that.
Can change to in the cards menu
Learn to format data display in a visualization... font, numeric format, display unit
Can swap measures to dimensions if needed (Such as store number) Format options in pill dropdown
Be able to provide a basic explanation of the.... Canvas, Shelves, Cards, Pills
Canvas - raw UI where you can do any possibility of work Shelf - above main block of space: Row, Column Pill - little pill that sits in the shelf Cards - Filter, Marks, little squares left of canvas
Use the "data interpreter" when the first row of your XLSX file isn't the field names
Check little box on the left side, Will combine the headings, but you can manipulate the data to fit your needs in tableau
How do you show a filter to the user?
Click on pill drop down arrow and hit "Show Filter"
Learn how to change analysis from SUM to something else.
Click the down arrow in the little pill and gives you many different options
Learn to build a highlight table - and why you might choose one instead of a crosstab.
Color draws user attention
What is a "CSV" file?
Comma Separated Values
Be able to explain continuous vs. discrete.
Continuous - infinite possible values Green in UI Discrete - Finite set of values Blue in UI
Which divides data into "buckets" or "bins"?
Dimensions
How is a discrete date dimension different from a continuous date dimension?
Discrete - only filtering for specific dimensions Continuous - stream of dates going infinitely into the future
Learn how discrete and continuous dates work differently in your crosstabs (and other visualizations)
Discrete quarterly data would sh ow all data in q1 for all years summed (discrete put headings on the top) Continuous assumes we would want to have contiuous data displayed on an axis on bar graphs (continous display like a graph)
Learn to control the color of bars in a visualization using a variable... a discrete dimension, for example.
Drag dimension into the color square in marks card
Learn to build a crosstab using drag-and-drop ... and also using double-click.
Drag dimensions and drag measure into canvas Could also drag on shelf Or can double click
Display labels for the bars
Drag measure into label in the marks card
Why filter data?
Focus user attention
Adding labels, formatting labels (including "suffixes" to numeric formats), tooltips...
Format by hitting specific pill and hitting down arrow and format and do whatever you want
Learn to create a bubble chart
Found in "Show Me" Can duplicate pie chart and change it to bubble chart
Learn to create a pie chart
Found on the "Show Me"
Learn to split a field - automatic split and "custom" split... using delimiter characters and patterns.
Hit down arrow and there's an option to split ( separates data based of a character like a comma)
Learn to use the "data pane." What do you do if it disappears?
Hit the tab on the bottom
How does a user view the "Tooltips" for a visualization? How do you edit tooltips to make them more helpful to a user?
It is on the marks card, can edit with tooltips to rename information such as the "N umber of records" so people better understand
Learn to save your Tableau file as a Packaged Workbook
Just save it as a packaged workbook
Learn to manipulate the Color marks card, including color palettes and stepped colors.
Just use card and manipulate color
Which is used to do mathematical calculations?
Measures
What's the difference between a "packaged" workbook and a regular Tableau Workbook?
Packaged copies everything, regular only copies relevant information
When might it be a bad idea?
People do not know what the data is showing Can mess up results based on visualization
What is the value of doing that?
People with no clue can still interact with chart and manipulate it
What information does a pie chart convey? A bubble chart?
Percentage of parts compared to the whole Each wedge is dimension
What is a dimension? How is it used?
Qualitative - Categorize and divide the data
What is a measure? How is it used?
Quantitative - fields which are aggregated
How do you use the Analytics tab to add subtotals and grand totals to your visualization?
Right next to data pane, can just drag "Totals"
Learn to connect to a text file
Same as connecting to a excel sheet or opening any document ever
Learn to connect to an Excel data file using Tableau
Same way you open any file in applications like excel
Learn to use the "Show Me" tab
Show me - has various options to pick from (This is where the highlight table is)
Sort the bars
Sort icon on horizontal axis
TopN filters
Take sales person into filter Use all Hit top card Specify numbers you want
Why does double-click sometimes not create a crosstab (e.g. with "state")?
The data is identified as geographical data only a problem if you double click Instead just drag and it will work as intended
What is the purpose for "Detail" marks?
When you hover over bars you can see more information
Learn to create a "Calculated Field"...
click on column and hit down arrow and says "Create Calculated Field"
Learn to rename a field
double click and you can rename
Learn to filter on discrete and continuous dimension
drag into the filer card to get option menu, can show filter on side of screen if wanted
Learn to build bar graphs
drag measure into column and it automatically makes bar chart
How does that affect filtering?
gives you different filtering options
Learn to build a calculated field that uses the IF-THEN-ELSE logic function.
have to use END when typ[ing logical functions If(text) Then(TEXT) Else(TEXT)
Add a second bar graph to your visualization
just drag and drop another measure and it will split into 2 dif bar charts Can also fit different views, little drop down at top of screen
Learn to sort the results of your crosstab
usually just hit down on the pill arrow and theres a sort option
What does Mr. Olson mean by "What happens in Tableau stays in Tableau"?
we connect to external data but we do not change it
