XY Graph

Display X-Y plot of signals using MATLAB figure window

Library:
Simulink / Sinks
HDL Coder / Sinks

Description

The XY Graph block displays an X-Y plot of its inputs in a MATLAB^® figure window.

The block has two scalar inputs. The block plots data from the first input (the x direction) against data from the second input (the y direction). (See Port Location After Rotating or Flipping for a description of the port order for various block orientations.) This block is useful for examining limit cycles and other two-state data. Data outside the specified range does not appear.

A figure window appears for each XY Graph block in the model at the start of simulation.

Note

The XY Graph block does not support stepping back in a simulation.

Ports

Input

expand all

`Port_1` — X-axis values
scalar

Plot input as x values on an X-Y plot. See Port Location After Rotating or Flipping for a description of the port order for various block orientations.

`Port_2` — Y-axis values
scalar

Plot input as y values on an X-Y plot. See Port Location After Rotating or Flipping for a description of the port order for various block orientations.

Parameters

expand all

`X-min` — Minimum x
`-1` (default) | real number

Specify the minimum x-axis value. Data below the minimum x is ignored.

Programmatic Use

Block Parameter: xmin

Type: character vector

Values: real number

Default: '-1'

`X-max` — Maximum x
`1` (default) | real number

Specify the maximum x-axis value. Data above the maximum x is ignored.

Programmatic Use

Block Parameter: xmax

Type: character vector

Values: real number

Default: '1'

`Y-min` — Minimum y
`-1` (default) | real number

Specify the minimum y-axis value. Data below the minimum y is ignored.

Programmatic Use

Block Parameter: ymin

Type: character vector

Values: real number

Default: '-1'

`Y-max` — Maximum y
`1` (default) | real number

Specify the maximum y-axis value. Data above the maximum y is ignored.

Programmatic Use

Block Parameter: ymax

Type: character vector

Values: real number

Default: '1'

`Sample time` — Sample time
`-1` (default) | positive number

Specify the time interval between samples. To inherit the sample time, set this parameter to -1. For more information, see Specify Sample Time.

Programmatic Use

Block Parameter: st

Type: character vector

Values: '-1' (for inherited) | positive number

Default: '-1'
