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.

2025: Function @code{ifplot()} draws a graph of real zeros of a bi-variate
2026: function.
2027: Function @code{conplot()} plots the contour lines for a same argument.
2028: Function @code{plot()} draws the graph of a uninivariate function.
2029: These functions are available on UNIX version (on @code{X11}).
2030:
2031: @item
2032: The plotting functions for UNIX version are realized on remote process
2033: facilities described previously.
2034: The command for this is @samp{ox_plot} in @b{Asir} root directory.
2035: Of course, it must be activated by @code{ox_launch()}.
2036:
2037: @item
2038: Argument @var{func} is indispensable. Other arguments are optional.
2039: The format of optional arguments and their default values (parenthesized)
2040: are listed below.
2041:
2042: @table @var
2043: @item geometry
2044: Window size is specified by @var{[x,y]} in unit `dot.'
2045: (@var{[}@code{300},@code{300}@var{]} for UNIX version;
2046:
2047: @item xrange, yrange
2048: Value ranges of the variables are specified by @var{[v,vmin,vmax]}.
2049: (@var{[v},@code{-2},@code{2}@var{]} for each variable.)
2050: If this specification is omitted, the indeterminate having the higher
2051: order in @var{func} is taken for @samp{x} and the one with lower order
2052: is taken for @samp{y}. To change this selection, specify explicitly
2053: by @var{xrange} and/or @var{yrange}.
2054: For an uni-variate function, the specification is mandatory.
2055:
2056: @item zrange
2057: This specification applies only to @code{conplot()}. The format is
2058: @var{[v,vmin,vmax} @code{[},@var{step} @code{]}@var{]}.
2059: If @var{step} is specified, the height difference of contours is set to
2060: @var{(vmax-vmin)/step}.
2061: (@var{[z},@code{-2},@code{2},@code{16}@var{]}.)
2062:
2063: @item id
2064: This specifies the number of the remote process by which you wish
2065: to draw a graph.
2066: (The number for the newest active process.)
2067:
2068: @item name
2069: The name of the window.
2070: (@code{Plot}.)
2071: The created window is titled @var{name:n/m} which means the @var{m}-th
2072: window of the process with process number @var{n}.
2073: These numbers are used for @code{plotover()}.
2074: @end table
2075:
2076: @item
2077: The maximum number of the windows that can be created on a process is
2078: 128.
2079:
2080: @item
2081: Function @code{plotover()} superposes reals zeros of its argument
2082: bi-variate function onto the specified window.
2083:
2084: @item
2085: Enlarged plot can be obtained for rectangular area which is specified,
2086: on an already existing window with a graph,
2087: by dragging cursor with the left button of mouse
2088: from the upper-left corner to lower-right corner
2089: and then releasing it.
2090: Then, a new window is created whose shape is similar to the specified
2091: area and whose size is determined so that the largest
2092: side of the new window has the same size of the largest side of
2093: the original window.
2094: If you wish to cancel the action, drag the cursor to any point
2095: above or left of the starting point.
2096:
2097: This facility is effective when @code{precise} button switch is
2098: inactive. If @code{precise} is selected and active, the area specified
2099: by the cursor dragging will be rewritten on the same window. This
2100: will be explained later.
2101: @item
2102: A click of the right button will display the current coordinates of
2103: the cursor at the bottom area of the window.
2104:
2105: @item
2106: Place the cursor at any point in the right marker area on
2107: a window created by @code{conplot()},
2108: and drag the cursor with the middle mutton. Then you will find the contour lines changing
2109: their colors depending on the movement of the cursor and the
2110: corresponding height level displayed on the upper right corner of
2111: the window.
2112:
2113: @item
2114: Several operations are available on the window: by button operations
2115: for UNIX version, and pull-down menus for Macintosh version.
2116:
2117: @table @code
2118: @item quit
2119: Destroys (kills) the window. While computing, quit the current
2120: computation.
2121: If one wants to interrupt the computation, use @code{ox_reset()}.
2122:
2123: @item wide (toggle)
2124: Will display, on the same window, a new area enlarged by 10 times
2125: as large as the current area for both width-direction and
2126: height-direction. The current area will be indicated by a rectangle
2127: placed at the center. Area specification by dragging the cursor will
2128: create a new window with a plot of the graph in the specified area.
2129: @item precise (toggle)
2130: When selected and active,
2131: @code{ox_plot} redraws the specified area more precisely by integer
2132: arithmetic.
2133: This mode uses bisection method based on Sturm sequence computation to
2134: locate real zeros precisely. More precise plotting can be expected
2135: by this technique than by the default plotting technique, at the expense
2136: of significant increase of computing time. As you see by above
2137: explanation, this function is only effective to polynomials with
2138: rational coefficients.
2139: (Check how they differ for (x^2+y^2-1)^2.)
2140:
2141: @item formula
2142: Displays the expression for the graph.
2143:
2144: @item noaxis (toggle)
2145: Erase the coordinates.

2147:
2148: @item
2149: Program @samp{ox_plot} may consume much stack space depending on
2150: which machine it is running.
2151: You are recommended to set the stack size to about 16MB as large
2152: in @samp{.cshrc} for safe.
2153: To specify the size, put @code{limit stacksize 16m} for an example.
2154:
2155: @item
2156: You can customize various resources of a window on @code{X}, e.g.,
2157: coloring, shape of buttons etc.
2158: The default setting of resources is shown below.
2159: For @code{plot*form*shapeStyle} you can select among
2160: @t{rectangle}, @t{oval}, @t{ellipse}, and @t{roundedRectangle}.
