Curve Inquiry Commands¶

These functions provide a mechanism for obtaining information about specified curves.

Note

< > = Required user input.

[ ] = Optional user input.

[PyDV]: = Python Data Visualizer command-line prompt.

disp¶

Display the y-values in the specified curve(s).

[PyDV]: disp <curve-list>

dispx¶

Display the x-values in the specified curve(s).

[PyDV]: dispx <curve-list>

eval¶

Evaluate mathematical operations on curves.

[PyDV]: eval <curve-operations>

getattributes¶

Return (to the terminal) the attributes of a curve, such as: color, style, width, etc.

[PyDV]: getattributes <curve>

getdomain¶

Return (to the terminal) the domains for the list of curves.

[PyDV]: getdomain <curve-list>

getlabel¶

Return (to the terminal) the given curve’s label.

[PyDV]: getlabel <curve>

getnumpoints¶

Display the number of points for the given curve.

[PyDV]: getnumpoints <curve>

getrange¶

Return (to the terminal) the ranges for the list of curves.

[PyDV]: getrange <curve-list>

getx¶

Return the x values for a given y

[PyDV]: getx <curve-list> <y-value>

gety¶

Return the y values for a given x

[PyDV]: gety <curve-list> <x-value>

stats¶

Calculate the mean and standard deviation for the curves and display the results on the terminal.

[PyDV]: stats <curve-list>

getymin¶

Return xy-parings of the x values with the corresponding minimum y-value for the curve within the specified domain. If no domain is given, then the full domain range is used.

[PyDV]: getymin <curve> [<xmin> <xmax>]

getymax¶

Return xy-parings of the x values with the corresponding maximum y-value for the curve within the specified domain. If no domain is given, then the full domain range is used.

[PyDV]: getymax <curve> [<xmin> <xmax>]
