I have two survey's. Each had the same five quesions. I have created a chart that compares the number of yes answers for each question for the two survey's. Unfortuneatley, the same number of people were not queried the second time. In order to make a fair comparison, I need to show the percent that answered yes. I have two groups, one to show which survey, and one to show which question. I have created a summary that shows the number of people asked. Another summary shows the number that answered yes. A formula divides the two to get the percentage. Unfortunately the 3D Riser bar chart will only let me use one of the two summaries, and not the percentage from the formula. Any ideas how I can compare percentages between the two surveys?
