Dashboards and Data Stories

You have four finished worksheets from last quarter. Sales by region. Revenue by month. Your top ten products. A map of orders by state. Each one is fine on its own. But your VP does not want to flip through four tabs in a meeting. She wants one screen she can glance at and understand in ten seconds.

That single screen is a dashboard. A dashboard in Tableau is one view that holds several worksheets together and wires them so they tell one story. This chapter turns your loose charts into that screen, then shows you when a guided Story serves you better.

Why this matters

A worksheet answers one question. A dashboard answers a set of related questions at once, on a single page, for a real audience. In business that audience is busy: an executive, a client, a team lead with ninety seconds between meetings. If they have to click through five tabs to piece the picture together, they will not.

The skill here is arrangement. You make the important thing obvious, keep the layout working on a laptop and a phone, and let a click on one chart update the others. Get that right and your dashboard gets used. Get it wrong and it becomes another file nobody opens.

The Dashboard tab: your canvas

At the bottom of a Tableau workbook you have tabs, much like the tabs in a spreadsheet. The tab that opens a blank dashboard is the New Dashboard icon (it sits next to the New Worksheet tab). Click it and the pane on the left changes.

At the top of that pane is the Sheets list: every worksheet in your workbook. To build, you drag a worksheet from the Sheets list onto the blank canvas on the right. Drop a second one and Tableau places it beside or below the first. To trade one chart for another, select it in the dashboard, hover over the replacement, and use the Swap Sheets button.

Below the Sheets list is the Objects section. These are the pieces that are not charts:

Horizontal and Vertical: layout containers (covered just below)
Text: a title, a note, or an explanation
Image: a logo or a static picture
Web Page: a live web page embedded in the dashboard
Blank: an empty spacer you use to create white space
Navigation: a button that jumps the viewer to another dashboard
Download: a button that lets a viewer export a PDF, a PowerPoint slide, or a PNG image

You drag any of these onto the canvas the same way you drag a worksheet.

Tiled or floating

Every item you add is either tiled or floating. Tiled items snap into a single-layer grid. They never overlap, and they resize together as the dashboard resizes. This is the default and the safe choice. Floating items sit on top, layered wherever you drop them. A floating logo in a corner or a filter box over a map can look sharp, but floating items do not reflow, so they can drift on a different screen.

To drop something as floating, hold Shift while you drag it. To change an item you already placed, select it, open its menu (the small dropdown arrow), and choose Floating. A good habit: build with tiled objects, and float only when you deliberately want to layer.

Layout containers

A layout container is an invisible box that groups objects and arranges them for you. A Horizontal container lines its contents up in a row and shares the width among them. A Vertical container stacks its contents in a column and shares the height. Select a container, open its menu, and choose Distribute Evenly to give each item the same amount of space.

Containers are the secret to a dashboard that stays tidy when it resizes. Instead of nudging four charts by hand, you drop them into containers and let Tableau keep them aligned.

Try It Build a dashboard from two worksheets. You need a workbook with at least two finished worksheets (for example, one bar chart of Sales by Region and one line chart of Sales by Month).

At the bottom of the workbook, click the New Dashboard icon (the tab with a grid picture).

In the Dashboard pane on the left, leave Size on a fixed preset for now (the next section explains sizing).

From the Sheets list, drag your bar chart onto the left half of the blank canvas. Let go when the gray shaded area covers the left side.

From the Sheets list, drag your line chart onto the right half. Tableau tiles it beside the first.

From the Objects section, drag a Text object across the very top and type a plain title, such as “Regional Sales Overview.”

What did you notice? Two separate charts now read as one screen, and dragging the divider between them resizes both at once.

Sizing: make it work on every screen

In the Dashboard pane, the Size menu controls how the dashboard behaves when the window showing it changes shape. There are three modes.

Fixed size: the dashboard stays one exact size no matter the window. Tableau ships presets, such as a Desktop Browser size, or you set your own in pixels. Predictable, though it can leave empty margins or scrollbars on screens that do not match.
Automatic: the dashboard stretches to fill whatever window shows it. This works best with tiled layouts.
Range: the dashboard scales between a minimum and a maximum size that you set, then stops. A middle ground for screens that are similar but not identical.

Why this matters: a dashboard you build on a wide monitor can look broken on a laptop or a projector. If it is Fixed and the screen is smaller, viewers get scrollbars. If it is Automatic and you used floating objects, pieces drift. Choose the mode that matches where people will actually view the work.

Device layouts

Tableau goes one step further for phones and tablets. On the Dashboard tab, click Device Preview. Options appear above the canvas so you can switch between Device types (Desktop, Tablet, Phone) and specific Models and see how your dashboard looks on each.

You start with one Default layout. Under it you can add a Phone or Tablet layout. Each new layout is a child of Default that you tailor: hide a chart that is too dense for a small screen, reorder items, or let Tableau fit them to the width for vertical scrolling. Viewers automatically get the layout that matches their device.

You do not design three times over. Start with a solid Default, add a Phone layout only if people will view on phones, and adjust just the parts that break.

Dashboard actions: make the views work together

A static dashboard shows numbers. A wired one lets a viewer explore. The wiring is called an action: a rule that says “when someone interacts with this view, do that to the others.” Open the Dashboard menu and choose Actions to add one.

Four actions cover most needs:

Filter: clicking a mark in one view filters the others. Click the “West” bar and every chart on the page narrows to West. The fastest way to add this is the Use as Filter option on a view’s menu.
Highlight: clicking a mark dims everything unrelated and keeps the matching data bright across the dashboard, without removing anything.
Go to URL: clicking a mark opens a web link, such as a customer record in another system.
Go to Sheet: clicking a mark jumps the viewer to another worksheet, dashboard, or story in the same workbook. Handy for a summary that drills into detail.

Each action runs on a trigger you choose: on hover, on select (a click), or from a menu. Tableau offers more actions too, including Change Parameter and Change Set Values, which let a click adjust a parameter or a set. You will meet parameters and deeper filtering in Chapter 7. For now, one Filter action that links your charts is often all a dashboard needs.

Keep actions few. Every action a viewer cannot predict makes the dashboard feel unpredictable. One clear filter beats five hidden ones.

Stories: walk an audience through a point

A dashboard lets people explore in any order. Sometimes you do not want that. You want to lead a reader through a sequence: here is the problem, here is the cause, here is what we should do. That is a Story.

A Story in Tableau is a sequence of story points. A story point is one slide that holds a worksheet or a dashboard at a particular state, with its own filters, sorting, and annotations. Across the top sits a row of caption boxes, one per point, that double as a navigator: click a caption to jump to that point.

To build one, click the New Story tab at the bottom of the workbook. Drag a sheet or dashboard onto the canvas to create the first point, then click Add a caption and type a short line summarizing it. To add the next point, click Blank for a fresh slide or Duplicate to build on the current one, change the view (apply a filter, add an annotation), and click Update to save that point’s state.

When to use which:

Use a dashboard when the audience should explore freely and answer their own questions.
Use a Story when you are presenting a specific conclusion in a set order, like a slide deck built from live data.

Design principles: focus, hierarchy, white space

Tools do not make a dashboard good. Three habits do.

Focus. One dashboard answers one main question. If you cannot state that question in a sentence, split the work into two dashboards.

Hierarchy. People read top-left first. Put the headline number or chart there, and the supporting detail below and to the right. Size signals importance: the biggest element is the one you want seen first.

White space. Empty space earns its place. Gaps between charts, made with Blank objects or container padding, let the eye separate one idea from the next. A crammed dashboard reads slower than a sparse one.

In business: a quarterly sales review

Your VP’s ten-second screen might lay out like this:

+-------------------------------------------------------------+
|  Regional Sales Overview              [ Q3 v ]   title+filter|
+-------------------------------------------------------------+
|   $2.4M          +8% YoY          312 orders   (number row) |
+-------------------------------------------------------------+
|  Sales by Region             |  Sales by Month              |
|  (bar chart; click a bar     |  (line chart; updates when   |
|   to filter the whole page)  |   a region is clicked)       |
+------------------------------+------------------------------+
|  Top 10 Products (table)     |  Orders by State (map)       |
+-------------------------------------------------------------+

The title and a quarter filter sit across the top. A row of headline numbers answers “how did we do” at a glance. The bar chart of regions carries a Filter action, so clicking “West” narrows the month trend, the product table, and the map to West all at once. Everything is tiled inside containers, so it holds together when the VP opens it on a laptop. A separate Phone layout stacks the same pieces into one scrolling column for the sales reps in the field.

Common pitfalls

Cluttered dashboards. Ten charts on one page means none of them gets read. Cut to the few that answer the main question and move the rest to a second dashboard linked by a Go to Sheet action.

Fixed sizing that breaks elsewhere. A dashboard built at Fixed size on a 27-inch monitor gives everyone else scrollbars or dead space. If your audience uses varied screens, choose Automatic or Range, and add a Phone layout for mobile viewers.

Too many actions. Every hidden filter or highlight a viewer triggers by accident erodes trust in the numbers. Add actions on purpose, keep them few, and title the dashboard so people expect a click to filter.

Floating everything. Floating objects look precise on your screen and drift on others. Build with tiled objects and containers, and float only the rare item that truly needs layering.

Practice

Take two finished worksheets and build a dashboard from them, following the Try It. Give it a plain title and leave the Size on a fixed preset.
Add one Filter action so clicking a bar in one chart filters the other. Test it: click a mark and confirm the second chart responds.
Switch the dashboard’s Size from Fixed to Automatic, then resize the window. Note what stays tidy and what breaks, and decide which mode fits your audience.
Turn the same content into a two-point Story: point one shows the overview, point two shows a single region filtered, each with a one-line caption. Decide whether the dashboard or the Story communicates your point better.

Chapter 7 covers interactivity in depth: filters, parameters, and the controls that let viewers reshape a dashboard themselves.
