Add Median to Chart

QI Macros has to go through many gyrations to get Excel to draw a good box plot. The values for the boxes are not the actual Q1, Median and Q3. They are the height of the box, not the actual value. To show the Q1, Q3 and/or the median, you will want to add another data series to the chart as follows:

To add the median label to the chart:

  1. Select and copy the Median, Q1, and/or Q3 values from the data sheet
    select and copy median calculations
  2. Paste the Data into the Box and Whisker Plot
    add data to box plot
  3. Now you have a marker for the data point. To add a label for the value: right click on the new point on the chart (in-between the two boxes) and click Add Data Labels:
    add labels to data points
  4. Here is what the box should look like.

  6. Here is what the final box looks like
