Enhancing your data team with ours
Our consultants come armed with both technical and soft skills to support you to make the most of your data.
The Data School has been paramount to our success at JLL. It has allowed us to bring in highly skilled Tableau and Alteryx consultants. It saves considerable time trying to recruit contractors as I know their skills and training are to the highest standard. Over the past 5 years my team has developed analytical insights which have generated multi million dollar savings of which a considerable amount can be attributed to the Data School consultants we have had working on projects.

Configuring the Find & Replace Tool in Alteryx
Alteryx defines the Find & Replace tool as
"Search for data in one field from one data stream and replace it with a specified field from a different data stream"

Combining Bar and Pie Charts in Tableau: A Cleaner Way to Show Totals and Percentages
When you're trying to show both absolute values and percentages of total, using separate bar and pie charts often creates more confusion than clarity.

How to Offset Label Position in Tableau
