Zoom-line Dual Y-Axis Chart
The FusionCharts Suite XT zoom-line dual y-axis chart, like the zoom-line chart, is used to analyze data at macroscopic and microscopic levels. With the dual y-axis, this chart can be used to plot data that belongs to datasets having different numeric units on the same chart—an advantage over using the conventional zoom-line chart.
Another advantage of using the zoom-line dual y-axis chart is when you want to compare two datasets where the values of one dataset are spread over a smaller interval, while the values of another have large intervals between them. In this case, if the zoom-line chart was used, the dataset with the smaller interval will be plotted as a straight line.
The chart below shows a zoom-line dual y-axis chart created to compare unique footfall with the sales (in dollars), for each day of the previous year.
