  I need to generate graphs by code, but there are many properties that do not can modified.
  The size of the graph (Width,Height), the format of data (formatValue).
  It is necessary to create an object in particular within the TfrxChartView.
  From the FastReport is can to modify properties, but by code i do not know to do it.
  
  CODE:
  Dim Grafica As IfrxChartView
  Set Grafica = report.CreateReportObjectEx(page, "TfrxChartView", "Char_View1")
  Set database = report.CreateReportObjectEx(page, "TfrxADODatabase", "Database")
  Set sql_query = report.CreateReportObjectEx(page, "TfrxADOQuery", "SQL_Query1")
  report.SelectDataset True, sql_query
  Grafica.GetSeriesItem(Grafica.SeriesCount - 1).XAxisType = xtNumber
  Grafica.GetSeriesItem(Grafica.SeriesCount - 1).DataSet = sql_query
  Grafica.GetSeriesItem(Grafica.SeriesCount - 1).Title = "Grafica"
  Grafica.GetSeriesItem(Grafica.SeriesCount - 1).DataSet.ValueOfField ("TITULAR")
  Grafica.GetSeriesItem(Grafica.SeriesCount - 1).XSource = "sql_query1.""TITULAR"""
  Grafica.GetSeriesItem(Grafica.SeriesCount - 1).YSource = "sql_query1.""Importe"""

  
  Actually, TfrxChartView built on top of TeeChart library that provides huge amout of different properties. We export some of then into IfrxChartView and accompanying interfaces.
  
  To set the size of graph you can cast IfrxChartView to IfrxComponent and set Width and Height properties.
  
  Unfortunately, there is no way to set the formatValue at this time. We consider to add such feature after release of FR Studio 4.
