Overview
FusionCharts are general-purpose charts, such as column, bar, line, area, and pie. Chart data can be supplied in a few different ways, depending on your needs. The chart can use statically defined data, or the data can load dynamically from an RPG program or database.
...
- Animation makes charts fancier but causes pages to load more slowly. Also, because the chart is loaded first, slow charts cause other elements on your page to load slowly.
- If you are using RPG to generate the chart XML or JSON, then this field is ignored.
chart overlay - If the property is set to true, then the chart background color will depend on the chart type. Otherwise, the chart background color will be transparent. Read further in the FusionCharts setTransparent method.
...
When using a function to handle the click, the first parameter is assigned with the name of the data column/bar/point that was clicked. User defined functions can be defined in Custom External Javascript.
Chart Data
One way to define the data presented on the chart is by setting the names and values from within Visual Designer. Defining data this way, the names and values fields are comma-separated lists, and the lists must be the same length. Note, however, that only single-series charts are supported when chart data is supplied this way.
...
Hint: it is possible to create a dynamic chart by binding the names and values properties to your RPG program. However, other methods may better suit your needs.
...
Database-Driven Chart
Another method to generate dynamic charts is by specifying a database file to drive the data. This is a fairly simple way to connect a chart widget to a database–no XML or JSON need be generated by your RPG program. However, database-driven charts can only display a single data series. (For multi-series charts, see the Dynamic Chart section below.)
...
Normally you can preview a design by clicking Launch > Launch Preview..., and a preview will open in a new tab. With Database-Driven charts, however, the preview cannot connect to a database file because it doesn't know the library. You will need to save and compile the display file, and then create an RPG program to drive the page. Your program may be as simple as this:
