A bullet sparkline is a variation of a bar graph where it can show a lot of data in a small amount of space. It is typically used when displaying performance data.
The bullet sparkline formula has the following syntax:
=BULLETSPARKLINE(measure, target, max, [good, bad, forecast, tickunit, colorScheme, vertical, measureColor, targetColor, maxiColor, goodColor, badColor, forecastColor, allowMeasureOverMaxi, barSize])
The formula options are described below:
| Option | Description |
|---|---|
| measure | A number or reference that represents the length of the measure bar, such as 5 or "A1". |
| target | A number or reference that represents the location of the target line, such as 7 or "A2". |
| max | A number or reference that represents the maximum value of the sparkline, such as 10 or "A3". |
|
good Optional |
A number or reference that represents the length of the good bar, such as 3 or "A4". The default value is 0. |
|
bad Optional |
A number or reference that represents the length of the bad bar, such as 1 or "A5". The default value is 0. |
|
forecast Optional |
A number or reference that represents the length of the forecast line, such as 8 or "A6". The default value is 0. |
|
tickunit Optional |
A number or reference that represents the tick unit, such as 1 or "A7". The default value is 0. |
|
colorScheme Optional |
A string that represents a color scheme for displaying the sparkline. The default value is "#A0A0A0". |
|
vertical Optional |
A boolean value that indicates whether to display or not the sparkline vertically. The default value is false. |
|
measureColor Optional |
A color string that indicates the color of measure bar. |
|
targetColor Optional |
A color string that indicates the color of target line. |
|
maxiColor Optional |
A color string that indicates the color of the maxi area. |
|
goodColor Optional |
A color string that indicates the color of the good area. |
|
badColor Optional |
A color string that indicates the color of the bad area. |
|
forecastColor Optional |
A color string that indicates the color of the forecast line. |
|
allowMeasureOverMaxi Optional |
A Boolean value that indicates whether the measure can exceed maxi area. The default value of this parameter is false. |
|
barSize Optional |
A number value greater than 0 and equal to or less than 1, which indicates the percentage of bar width or height according to the cell width or height. |
Consider a scenario where an electronic store wants to analyze the performance of its product sales through its defined measures. A bullet sparkline can showcase all the required factors, effectively shown in the image below.
