Determine where to draw graphics objects - MATLAB newplot - 金宝app,下载188bet金宝搏,金宝搏官方网站

Syntax

newplot h = newplot h = newplot(sv)

Description

newplotprepares a figure and axes for subsequent graphics commands.

h = newplotprepares a figure and axes for subsequent graphics commands and returns the current axes.

h = newplot(sv)does not delete any objects specified by thesvargument, which can be a vector of graphics objects. The figure and axes containing the objects insvare prepared for plotting instead of the current axes of the current figure. Ifsvis empty,newplotbehaves as if it were called without any inputs.

Tips

To create a simple 2-D plot, use theplotfunction instead.

Usenewplotat the beginning of high-level graphics code to determine which figure and axes to target for graphics output. Callingnewplotcan change the current figure and current axes. Basically, there are three options when you are drawing graphics in existing figures and axes:

Add the new graphics without changing any properties or deleting any objects.
删除所有现有的对象处理hidden before drawing the new objects.
Delete all existing objects regardless of whether or not their handles are hidden, and reset most properties to their defaults before drawing the new objects (refer to the following table for specific information).

The figure and axesNextPlotproperties determine hownewplotbehaves. The following two tables describe this behavior with various property values.

First,newplotreads the current figure'sNextPlotproperty and acts accordingly.

NextPlot	What Happens
`new`	Create a new figure and use it as the current figure.
`add`	Draw to the current figure without clearing any graphics objects already present.
`replacechildren`	Remove all child objects whose`HandleVisibility`property is set to`on`and reset figure`NextPlot`property to`add`. This clears the current figure and is equivalent to issuing the`clf`command.
`replace`	Remove all child objects (regardless of the setting of the`HandleVisibility`property) and reset figure properties to their defaults, except `NextPlot`is reset to`add`regardless of user-defined defaults. `Position`,`Units`,`PaperPosition`, and`PaperUnits`are not reset. This clears and resets the current figure and is equivalent to issuing the`clfreset`command.

Afternewplotestablishes which figure to draw in, it reads the current axes'NextPlotproperty and acts accordingly.

NextPlot	Description
`add`	Add new plots to the existing axes. Do not delete existing plots or reset axes properties before displaying the new plot.
`replacechildren`	Delete existing plots before displaying the new plot. Reset the`ColorOrderIndex`and`LineStyleOrderIndex`axes properties to 1, but do not reset other axes properties. The next plot added to the axes uses the first color and line style based on the`ColorOrder`and`LineStyleOrder`properties of the axes. This value is similar to using`cla`before every new plot.
`replace`	Delete existing plots and reset all axes properties, except`Position`and`Units`, to their default values before displaying the new plot.
`replaceall`	Delete existing plots and reset all axes properties, except`Position`and`Units`, to their default values before displaying the new plot. This value is similar to using`cla reset`before every new plot. For axes with only oney-axes, the`replace`and`replaceall`values are equivalent. For axes with twoy-axes, the`replace`value affects only the active side while the`replaceall`value affects both sides.
