Six data display options on Chartlytics

11/14/2014
 

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 nth 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.

Picture
 

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.

Picture
 

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.

Picture
 

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.
