A Histogram sparkline makes it easier to see the quality distribution or sales performance distribution.

You can create a Histogram sparkline using the HistogramSparkline function in a formula: =HISTOGRAMSPARKLINE(dataRange,continuous?,paintLabel?,scale?,barWidth?,barColor?,labelColor?,edgeColor?). The function has the following parameters: dataRange: It's a range or calc array,such as "A1:C6" or "{1,2,2,3,3}". If a cell value isn't a valid number, it will be ignore. continuous: (optional) If it's true, the histogram is continuous. If it's false, the histogram is discrete. paintLabel: (optional) Boolean that represents whether to show the data label. scale: (optional) Number that represents the data binning width when histogram is continuous. (value > 0) barWidth: (optional) Number that represents the percent of bar width according to the average bar width. (value > 0 && value <= 1) barColor: (optional) String that represents the bar color. labelFontStyle: (optional) String that represents the data label font style. It supports custom font style, font weight, font family, font size. labelColor: (optional) String that represents the data label font color. It support CSS color. edgeColor: (optional) String that represents the color of bar edge.
