Data visualization

The visualization panel allows you conduct an online preliminary analysis. We use the bar plot, the pie plot and the violin plot to present the your different type data.

The bar plot is used to presents the distribution with large number of classes, like the question of Age (Q3).

The pie plot is used to presents the distribution with small number of classes, like the question of Education (Q4).

The violin plot is used to presents the distribution of each group and the distribution difference among the groups, like the question of AOA (Q7).

Not only can all charts be read, but you can also interact with them. Moving your mouse cursor on the parts of every charts, a pop window will give the detail of the highlighted part. Also, right-clicking a chart can save the chart as an image file on your computer.

Violin plot

A violin plot is a method of plotting numeric data. It is similar to a box plot, except that violin plot also show the probability density of the data at different values which are smoothed by a kernel density estimator.

On each side of the blue line is a kernel density estimation to show the distribution shape of the data. Wider sections of the violin plot represent a higher probability that members of the population will take on the given value, the skinnier sections represent a lower probability.

Inside each violin plot, MEAN ± SD is also drawn to help the violin plot present the data distribution clearly.
