185: A server or a client does not necessarily implement full specifications

188: to send data unknown to peers. It is realized by exchanging the list of
189: supported @b{CMO} and @b{SM}. The list is called mathcap.
190: Mathcap is also defined as a @b{CMO} and the elements are 32bit integers

203: the check by a mathcap is done before data is sent.
204: If @code{"ox_check"} switch of @code{ctrl} is set to 0,
205: the check is not done.

2029: For an uni-variate function, the specification is mandatory.
2030:
2031: @item zrange
2032: This specification applies only to @code{conplot()}. The format is
2033: @var{[v,vmin,vmax} @code{[},@var{step} @code{]}@var{]}.
2034: If @var{step} is specified, the height difference of contours is set to
2035: @var{(vmax-vmin)/step}.
2036: (@var{[z},@code{-2},@code{2},@code{16}@var{]}.)
2037:
2038: @item id
2039: This specifies the number of the remote process by which you wish
2040: to draw a graph.
2041: (The number for the newest active process.)
2042:
2043: @item name
2044: The name of the window.
2045: (@code{Plot}.)
2046: The created window is titled @var{name:n/m} which means the @var{m}-th
2047: window of the process with process number @var{n}.
2048: These numbers are used for @code{plotover()}.

2052: The maximum number of the windows that can be created on a process is
2053: 128.

2055: @item
2056: Function @code{plotover()} superposes reals zeros of its argument
2057: bi-variate function onto the specified window.
2058:
2059: @item
2060: Enlarged plot can be obtained for rectangular area which is specified,
2061: on an already existing window with a graph,
2062: by dragging cursor with the left button of mouse
2063: from the upper-left corner to lower-right corner
2064: and then releasing it.
2065: Then, a new window is created whose shape is similar to the specified
2066: area and whose size is determined so that the largest
2067: side of the new window has the same size of the largest side of
2068: the original window.
2069: If you wish to cancel the action, drag the cursor to any point
2070: above or left of the starting point.
2071:
2072: This facility is effective when @code{precise} button switch is
2073: inactive. If @code{precise} is selected and active, the area specified
2074: by the cursor dragging will be rewritten on the same window. This
2075: will be explained later.
2076: @item
2077: A click of the right button will display the current coordinates of
2078: the cursor at the bottom area of the window.
2079:
2080: @item
2081: Place the cursor at any point in the right marker area on
2082: a window created by @code{conplot()},
2083: and drag the cursor with the middle mutton. Then you will find the contour lines changing
2084: their colors depending on the movement of the cursor and the
2085: corresponding height level displayed on the upper right corner of
2086: the window.
2087:
2088: @item
2089: Several operations are available on the window: by button operations
2090: for UNIX version, and pull-down menus for Macintosh version.
2091:
2092: @table @code
2093: @item quit
2094: Destroys (kills) the window. While computing, quit the current
2095: computation.
2096: If one wants to interrupt the computation, use @code{ox_reset()}.
2097:
2098: @item wide (toggle)
2099: Will display, on the same window, a new area enlarged by 10 times
2100: as large as the current area for both width-direction and
2101: height-direction. The current area will be indicated by a rectangle
2102: placed at the center. Area specification by dragging the cursor will
2103: create a new window with a plot of the graph in the specified area.
2104: @item precise (toggle)
2105: When selected and active,
2106: @code{ox_plot} redraws the specified area more precisely by integer
2107: arithmetic.
2108: This mode uses bisection method based on Sturm sequence computation to
2109: locate real zeros precisely. More precise plotting can be expected
2110: by this technique than by the default plotting technique, at the expense
2111: of significant increase of computing time. As you see by above
2112: explanation, this function is only effective to polynomials with
2113: rational coefficients.
2114: (Check how they differ for (x^2+y^2-1)^2.)
2115:
2116: @item formula
2117: Displays the expression for the graph.
2118:
2119: @item noaxis (toggle)
2120: Erase the coordinates.

2124: Program @samp{ox_plot} may consume much stack space depending on
2125: which machine it is running.
2126: You are recommended to set the stack size to about 16MB as large
2127: in @samp{.cshrc} for safe.
2128: To specify the size, put @code{limit stacksize 16m} for an example.

2130: @item
2131: You can customize various resources of a window on @code{X}, e.g.,
2132: coloring, shape of buttons etc.
2133: The default setting of resources is shown below.
2134: For @code{plot*form*shapeStyle} you can select among
2135: @t{rectangle}, @t{oval}, @t{ellipse}, and @t{roundedRectangle}.
