Many reasons exist for why chart users would explore a set of data displayed across time. Some people use functional assessment data and need to use a geometric mean to ascertain the level line. Other people may chart the scores of 8 different people, therefore stacked data represent each person's performance on the chart. Chartlytics allows chart users different options for data display: First, Median, Geometric Mean, Minimum, Maximum, and Stacked (Future release will include Summed).

**First**data point.**First**shows the first data point recorded in a series of data points (frequency, duration, or latency). The example below shows four measures taken in one day.**First**data point charted means showing the first data point of the day/week/month.To select

**First**data point go to the Options tab. Click on it. Next Click on**First**. The chart will display the first data point of the measures for the day/week/month.**Median**data point.

**Median**refers to the “middle number” in a sorted list of numbers. The example below shows four numbers for the acceleration data.

**Median**data point charted means showing the middle data point of the day/week/month.

To select

**Median**data point go to the Options tab. Click on it. Next Click on**Median**. The chart will display the median data point for acceleration and deceleration data for the day/week/month.**Stacked**data point.

**Stacked**shows all of the measured data stacked on one line.

**Stacked**data point charted means showing the spread of all data point for a specific day/week/month.

**Geometric Mean**data point.

**Geometric Mean**describes a special type of average where we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. Also described as for

**n**numbers, multiply them all together and then take the

**n**th root. The example below shows four numbers for the acceleration data.

To select

**Geometric Mean**data point go to the Options tab. Click on it. Next Click on**Geometric Mean**. The chart will display the geometric mean data point for acceleration and deceleration data for the day/week/month.**Minimum**data point.

**Minimum**refers to the minimum value in a list of numbers or data set. The example below shows four numbers for the acceleration data.

**Minimum**data point charted means showing the minimum (lowest) data point of the day/week/month.

To select

**Minimum**data point go to the Options tab. Click on it. Next Click on**Minimum**. The chart will display the median data point for acceleration and deceleration data for the day/week/month.**Maximum**data point.

**Maximum**refers to the greatest value in a list of numbers or data set. The example below shows four numbers for the acceleration data.

**Maximum**data point charted means showing the maximum (highest) data point of the day/week/month.

To select

**Maximum**data point go to the Options tab. Click on it. Next Click on**Maximum**. The chart will display the median data point for acceleration and deceleration data for the day/week/month.**Stacked**data point.

**Stacked**shows all of the measured data stacked on one line.

**Stacked**data point charted means showing the spread of all data point for a specific day/week/month.

To select

**Stacked**data point go to the Options tab. Click on it. Next Click on**Stacked**. The chart will display the median data point for acceleration and deceleration data for the day/week/month.An example of what stacked dots look like appear below.
