Using the control

In order to start using the control, you need to drag and drop the Chart control into a web panel (or transaction). You will then see the chart in your web form and its properties will be shown in the Properties window (which can be activated from the View menu). In addition, when you drop the chart control, an SDT is consolidated: the GXChart.

The idea here is that you will give the chart control a GXChart SDT-based variable containing the x,y values that have to be displayed in the chart. The GXChart SDT contains 2 fields:

  • Categories: these are the X values to be displayed in the X axis.
  • Series (collection):
    • Name: the name of the series
    • Values: these are the Y values. Each of the values in a series belongs to a category. That is to say, the series should have as many values as there are categories (X=category, Y= series value)

As you may have realized, a Series in a GXChart actually contains a collection of series. This allows you to chart "more than one value" belonging to a category. Consequently, it is possible to create a chart representing, for example, the incomes and expenses for a given period.


&serie.Name = "Incomes"
&serie =new()
&serie.Name = "Outcomes"
//&gxchart is defined as GXChart //&serie is defined as Gxchart.serie

The example shown above will create a graph as follows:
