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.

• XY scatter plot with markers of varying size and/or color (sometimes also called bubble chart).
• Complete the following steps to display an array of points on a single-plot XY graph. Add an XY graph to the front panel. Build a block diagram with the following objects: Divide function; Multiply function; Sine function; Bundle function; For Loop around all objects on the block diagram except the XY graph terminal; Wire the x/y output of the.

Note

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

Input

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.

Data Types: single double int8 int16 int32 int64 uint8 uint16 uint32 uint64 Boolean fixed point

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

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

Programmatic Use

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

Programmatic Use

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

Programmatic Use

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

Programmatic Use

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

Description :: All Functions

Enter an Equation using the variables x and/or y and an =, press Go:

Description

It can plot an equation where x and y are related somehow (not just y=...), like these:

Examples:

• x^2+y^2=9 (an equation of a circle with a radius of 3)
• sin(x)+cos(y)=0.5
• 2x-3y=1
• cos(x^2)=y
• (x-3)(x+3)=y^2
• y=x^2

If you don't include an equals sign, it will assume you mean '=0'

It has not been well tested, so have fun with it, but don't trust it.

If it gives you problems, let me know.

Note: it may take a few seconds to finish, because it has to do lots of calculations.

Graph Plotting Tool

If you just want to graph a function in 'y=...' style you may prefer Function Grapher and Calculator

Zooming

Use the zoom slider (to the left zooms in, to the right zooms out).

To reset the zoom to the original bounds click on the Reset button.

Dragging

Click-and-drag to move the graph around. If you just click-and-release (without dragging), then the spot you clicked on will be the new center

Note: the plots use computer calculations. Round-off can cause errors or values can be missed completely.
