Introduction to Drag-able Chart
Drag-able charts are a special set of charts that allow you to visually manipulate the data on a chart and then submit it back. These charts can be used intensively for simulations, financial planning, etc.
In this section, you will be introduced to the:
-
Basics of drag-able charts
-
Types of drag-able charts
Basics of Drag-able Charts
Drag-able charts allow you to visually morph the data to update the figures on the chart. These charts derive their basic features from the multi-series column, the multi-series line, and the multi-series area charts.
FusionCharts Suite XT offers the following three types of drag-able charts:
-
Drag-able column 2D chart
-
Drag-able line 2D chart
-
Drag-able area 2D chart
Once you are done with the visual updating of data, you can submit the data:
-
Either back to the server as form data(like HTML Forms)
-
Or, to JavaScript functions present on the same page as the chart. These JavaScript functions can then process the data and do the needful.
Types of Drag-able Charts
Drag-able Column 2D
A simple drag-able column 2D chart looks like this:
