The XY Dataset
An XY Dataset plots pairs of values as points on the chart. The XY charts have two numeric axes.
Handing this dataset to a chart, the chart will plot the data by column by default. Here is a bar an xy line chart example:
A Row-based Dataset Example
To plot the data by rows, you must add the by-row property to the action sequence component definition. (You can set this property in the Design Studio by checking the Chart Row Dimension checkbox.) Also, your data must be arranged in row format.
Here is a bar chart example, with the same dataset plotted by rows:
Unlike the categorical dataset, arranging the dataset by rows does not change the plotting of the data on the chart. The exact same chart as above would be generated by this dataset:
