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.
