These are the changes to support defalt chart and single chart type (as for IRSA release)

• Remove chart selection from chart area
• Use dropdown for chart selection (can be omitted if single chart type is used)
• Populate current values in chart options
• Support Clear and Reset in chart options
• For tables, connected to charts, if no default parameters are specified, default chart is an XY plot with CATALOG_COORD_COLS (used to produce an overlay) for catalogs or two first numeric columns for other tables.
• Label, matching column expression, and unit, matching table model, are default parameters for both app and api now.
