## COUNTOUR Contour Object Properties

Section: Handle-Based Graphics

### Usage

Below is a summary of the properties for a line series.-
`contourmatrix`

-`array`

- the matrix containing contour data for the plot. This is a`2 x N`

matrix containing x and y coordinates for points on the contours. In addition, each contour line starts with a column containing the number of points and the contour value. -
`displayname`

-`string`

- The name of this line series as it appears in a legend. -
`floating`

-`{'on','off'}`

- set to on to have floating (3D) contours -
`levellist`

-`vector`

- a vector of Z-values for the contours -
`levellistmode`

-`{'auto','manual'}`

- set to auto for automatic selection of Z-values of the contours. -
`linecolor`

- color of the contour lines. -
`linestyle`

-`{'-','--',':','-.','none'}`

- the line style to draw the contour in. -
`linewidth`

-`scalar`

- the width of the lines -
`parent`

-`handle`

- The axis that contains this object -
`tag`

-`string`

- A string that can be used to tag the object. -
`type`

-`string`

- Returns the string`'contour'`

. -
`userdata`

-`array`

- Available to store any variable you want in the handle object. -
`visible`

-`{'on','off'}`

- Controls visibility of the the line. -
`xdata`

-`matrix`

- Contains the x coordinates of the surface on which the zdata is defined. This can either be a monotonic vector of the same number of columns as`zdata`

, or a 2D matrix that is the same size as`zdata`

. -
`xdatamode`

-`{'auto','manual'}`

- When set to`'auto'`

FreeMat will autogenerate the x coordinates for the contours. These values will be`1,..,N`

where`N`

is the number of columns of`zdata`

. -
`ydata`

-`matrix`

- Contains the y coordinates of the surface on which the zdata is defined. This can either be a monotonic vector of the same number of rows as`zdata`

or a 2D matrix that is the same size as`zdata`

. -
`ydatamode`

-`{'auto','manual'}`

- When set to`'auto'`

FreeMat will autogenerate the y coordinates for the contour data. -
`zdata`

-`matrix`

- The matrix of z values that are to be contoured.
