Cascade

A cascade sparkline uses vertical or horizontal bars to display the data. This makes it easier to compare data values.

You can create a cascade sparkline using the CascadeSparkline function in a formula: =CASCADESPARKLINE(pointsRange, pointIndex, labelsRange?, minimum?, maximum?, colorPositive?, colorNegative?, vertical?, itemTypeRange?). The function has the following parameters: pointsRange: Reference that represents the range of cells that contain values, such as "B2:B8". pointIndex: Number or reference that represents the index of the points. The pointIndex is >= 1 such as 1 or "D2". labelsRange: (optional) Reference that represents the range of cells that contains the labels, such as "A2:A8"; default value is no label. minimum: (optional) Number or reference that represents the minimum values of the display area, such as -2000; the default value is the minimum of the sum (the sum of the points' value). maximum: (optional) Number or reference that represents the maximum values of the display area, such as 6000; the default value is the maximum of the sum (the sum of the points' value). colorPositive: (optional) String that represents the color of the first or last positive sparkline's box (this point's value is positive); default value is "#8CBF64". colorNegative: (optional) String that represents the color of the first or last negative sparkline's box (this point's value is negative); default value is "#D6604D". vertical: (optional) Boolean that represents whether the box's direction is vertical or horizontal; default value is false. itemTypeRange: (optional) Array or reference that represents the all item types of data range. The value should be {"-", "+", "="} or "A1:A7" that reference the value of {"+", "-", "="}. And "+" as positive change, "-" as negative change and "=" for total columns. colorTotal: (optional) String that represents the color of the last sparkline's box when itemTypeRange did not exist. Or represents the color of the result sparkline's box when itemTypeRange exists..
