Zoom In Tooltip in Tableau*For more step-by-step guides to creating different chart types in Tableau by Jeffery Shaffer, follow the link below: Tips Volume 13 (Tip #2)?I showed a zoom in feature on a map. In that example I used a small map on a Dashboard canvas and set the tooltip using a larger map with labels. This creates a zoom feature on the map, keeping the map small on the dashboard, but zooming in on hover. In this example, I will show a zoom feature on a scatterplot to zoom in on dots that are very close to each other or on top of each other. This is done using Bins.Step 1: Build a Scatter PlotUsing the?World Indicators Data:?????Double-click?Life Expectancy Female?to move it to Rows.?????Double-click?Birth Rate?to move it to Columns.?????Right-click on?Life Expectancy Female?on the Rows, select "Measures (Sum)" and change it to Average.?????Right-click on?Birth Rate?on the Rows, select "Measures (Sum)" and change it to Average.?????Double-click?Country?to move it to Details on the Marks card.?????Move?Region?to Color on the Marks card.?????Move?Year?to Filters and select "Year". Check "2012" to filter the data to 2012.?????Move?Population Total?to Size on the Marks card.?????Right-click on?Population?on the Marks Card, select "Measures (Sum)" and change it to Average.?????Using the dropdown box on the Marks card, select "Circles".?????Select Size on the Marks card and adjust the size to make the circles larger.?????Select Color on the Marks card and set Opacity to 65%.?????Select Border and pick a medium gray color.?????Double-click the y-axis and select "Fixed" and set the "Fixed Start" to 40.?????Select the "Tick Marks" tab and select "Fixed" and set the fixed "Tick Interval" to 10.?????Double-click the x-axis and select "Fixed" and set the "Fixed Start" to .01.?????Select the "Tick Marks" tab and select "Fixed" and set the fixed "Tick Interval" to .01 (which is 1%).You should now have a scatter plot similar to the image below.Step 2: Build the Zoom Worksheet?????Right-click on the worksheet tab at the bottom and select "Duplicate". This will make a second copy of the exact same worksheet.?????Right-click on the new worksheet tab at the bottom and select "Rename". Rename the worksheet "Zoom".On the new Zoom worksheet:?????Double-click the y-axis and select "Automatic" and uncheck "Include Zero".?????Double-click the x-axis and select "Automatic" and uncheck "Include Zero".?????Set the Size on the Mark's Card bigger.Step 3: Create Two Bins?????Right-click on?Life Expectancy Female?in the Data pane, select "Create" and "Bins...". Set the Bin Size to 10. Click OK.?????Right-click on?Birth Rate?in the Data pane, select "Create" and "Bins...". Set the Bin Size to .01. Click OK.Step 4: Build the TooltipOn the original scatter plot worksheet:?????Drag?Life Exectancy Female (Bin)?to Details on the Marks Card.?????Drag?Birth Rate (Bin)?to Details on the Marks Card.?????Select Tooltip on the Marks Card.?????Add two line breaks at the bottom of the tooltip.?????Select "Insert" and "Sheets" and select the new "Zoom" worksheet. This will insert the Zoom sheet into the tooltip.?????Change the value of maxwidth and maxheight to 600 (or desired size).?????Erase <All Fields> in the filter quotes.?????While inside the Filter quotes, click "Insert" and select?Life Exectancy Female (Bin).?????Type a comma and then click "Insert" and select?Birth Rate (Bin).The new sheet added in the Tooltip should look like this:<Sheet name="Zoom" maxwidth="600" maxheight="600" filter="<Life Expectancy Female (bin)>,<Birth Rate (bin)>">?The final result is a Tooltip with a zoom into a quadrant the size of each bin. Note - the bin size can also be controlled by a parameter, which would allow the user to control the zoom level.Map Zoom ExampleIn?this map example?I bin the Latitude and Longitude (X & Y in this dataset) to achieve a map zoom from a density map, down to the points on the map inside a few blocks.Tooltip:<Sheet name="Zoom" maxwidth="500" maxheight="500" filter="<X (bin)>,<Y (bin)>">?I hope you find this information useful.
