Declaration:

TFrmPlots.ShowColIdx (Col: integer; llx, lly, urx, ury: double; Caption: string): integer;

Sets the plot window into column/index mode and displays the data according to the parameters. The parameter Col specifies the column to be displayed. The parameters llx, lly, urx, ury define the range of the axes. llx and lly define the lower left point of the diagram, urx and ury define the upper right point. Setting all four parameters to zero forces an automatic zoom so that all data points are visible. The parameter Caption defines the caption to be displayed in the top right of the chart. The function returns the following error codes:  0 ... everything is OK -1 ... Col is out of range -3 ... the x axis has zero range -4 ... the y axis has zero range
