Plotdata

Plotdata-func

Description

This function returns the designated dataset of the index number plot at (rowNum, colNum) panel.of the active layer.

Syntax

dataset plotdata(int nIndex, int nDesignation, int rowNum = 0, int colNum = 0)

Parameter

nIndex

Index number of plot, which can be:

• plot index, e.g. 1 for the plot listed first in the layer (more about plot order).
• asterisk (*) which denotes all plots in layer.
• asterisk-dash (*-) which denotes all plots in layer except fitted curves.

nDesignation

The column type enum

• X: X Value
• Y: Y Value
• Z: Z Value
• XE: X Error
• YE: Y Error

rowNum

The row number of panel.

columnNum

The column number of panel.

Return

Return the designated dataset of the index number plot at (rowNum, colNum) panel.
