A strange name but Sparklines is a useful new part of Excel which makes simple single-cell graphs in Excel for Windows or Mac.
Mea Culpa – we thought that ‘Sparklines’ was a fancy name made up by Microsoft after a long liquid lunch … Office Watch readers, John F, Nick M and Peter B all pointed us to the facts. Sparklines were named by Edward Tufte for “small, high resolution graphics embedded in a context of words, numbers, images“. It was our mistake, sorry Mr Tufte.
We were mislead partly because Microsoft hasn’t acknowledged Mr Tufte’s contribution to their new feature. When you see Microsoft boasting about sparklines in Excel, spare a thought for the people who came up with the idea. Microsoft now has a patent over their implementation of sparklines in Excel .
Whatever it’s called, Sparklines is actually a useful new feature than even beginners can use to jazz up their worksheets.
Sparklines are simply tiny charts that show up within a cell in the Excel worksheet. These miniature charts represent changes for a particular row or column of entries. They have been in Excel since Excel 2010 for Windows and Excel 2011 for Mac.
If you ever have been scared off from the complications of formatting an Excel chart, especially for a simple need, then Sparklines is a good alternative.
How to Create Sparklines
To create Sparklines you need some kind of data report or a set of metrics so that you can insert Sparklines for the data in the required cell.
We have a worksheet with quarterly sales data. We’ll select the first 5 rows of data to add the Sparklines.
Once you select the data click Insert | Sparklines. As shown in the below screenshot you can add three types of Sparklines which are Lines, Column and Win/Loss. As shown in the icons for each type, different styles of charts will be inserted depending on the need.
Once you select the type of Sparkline as shown in the below screenshot “Create Sparklines” popup window will open where you need to enter the Data range i.e. the cell number for which the corresponding chart should be created and the Location range i.e. the cell in which you want the chart to be inserted. You can either insert the chart in a new cell or in the same cell where the data is appearing. If you select the latter then the chart will appear as a background in the cell. Let us see both these options. Now as shown in the below screenshot the data range is already selected. You can deselect the earlier selection and make new selection for the data range. For the Location range I chose a set of empty cells beside the “Qtr 4” column. After making the selections click the “OK” button. Note here that by clicking the small red arrow icons (see below screenshot) next to the textboxes for Data range and Location range the window will collapse and expand to show just a single corresponding textbox.
As you can see in the below screenshot tiny charts representing the data variations in each row is inserted in the empty cell to the right.
Once you insert Sparklines you can customize it in terms of color, style, etc. An array of Sparkline tools is available on the ribbon (see above screenshot) to change the color, mark high, low, negative points in the chart and hide or show those points in the Sparklines.
Note here that editing individual Sparkline in a group will apply the changes to all the charts in that group. However there is a workaround for that which I will explain shortly. To change the color or style of a chart select that particular Sparkline, automatically the Sparkline Tools ribbon will be displayed. Here you can select the required type, style, choose Sparkline and marker color and show or hide the marker points. I’ve selected the High Point and Low Point marker to be shown. Accordingly all the charts are displaying these marker points (see below screenshot). Suppose you decide not to show any markers then you will have just plain Line charts.
See the below screenshot where for the example I’ve selected the Sparkline type as “Column” and used blue color for high points and red color for the Sparklines.
Note here that although I selected only one row of data to apply the changes all the rows got affected. Next I inserted a separate Line Sparkline for a single row of data.
For one of the rows of data I’ve inserted a Line Sparkline in the column “Qtr 4” itself – cell F9. As a result the Sparkline is in the background of Cell F9.
When you create multiple Sparklines at once they are automatically put into a group. The formatting and settings of the Sparklines will be consistent unless you break the grouping.
You can see the grouping in the worksheet itself. When you click on a grouped sparkline, a thin blue line appears around all the sparkines in the group.
In this example the middle cell/sparkline is selected with the blue line around all three graphs in the group.
Breaking the Group
There is a simple option to break a group of Sparklines. For this select the required Sparkline, under Sparkline Tools | Design | Group click Ungroup. That particular cell will be ungrouped from the group.
If you want to break the entire group, then select all the cells and click on Ungroup. If you see in the screenshot below after ungrouping the first cell I’ve changed the color of that particular Sparkline to yellow but not disturbing the remaining Sparklines.
Again if you wish to group a set of individual Sparklines then simply select all of them and under Sparkline Tools | Design | Group click Group.
To delete a particular Sparkline or a group of Sparklines select the required Sparkline, under Sparkline Tools | Design | Group click Clear and choose the required option. That particular Sparkline or Sparklines will be cleared.
