The minimum of the quarterly lows are found in column G:Ĭolumn H calculates the ratio as a percentage:Ĭolumn I ranks the Column H for another purpose later on. To avoid that if there is no last price then the previous day’s last price is used:
Before the markets open there is no last price and the RTD formula returns a blank cell, which generates errors. There are two tabs: A Data tab and the Treemap chart tab.Ĭolumn A is the symbol column (stock symbols should always use “S.”).Īll formulas are simply entered and copied down.Ĭolumns B through E are the RTD functions for the quarterly data: For example, you could not create a treemap chart for a list of symbols based on the current session’s net percent change because any symbols with a negative net percentage change would be skipped. As the area of a rectangle cannot be a negative number then the treemap chart skips the symbol and value. Notice, that in the data in column I for the symbol D’s value is -1. The chart displays the values as rectangles which are raked from the highest value to the lowest value and the area of the rectangles represents the hierarchical value. The treemap chart displays categories by color and proximity and can easily display a group of data. The tree branches are represented by rectangles and each sub-branch is shown as a smaller rectangle. This view makes it easy to spot patterns, such as which markets are outperforming or underperforming in a group of markets.
A treemap chart provides a hierarchical view of your data. Microsoft® Excel 2016 and higher offer a new chart type: The Treemap.
