If false, graphs are converted to plots and displayed as usual. - renderer: (default: 'webgl'); for 3d graphics - 'webgl' (fastest) using hardware accelerated 3d; - 'canvas' (slower) using a 2d canvas, but may work better with transparency; - 'tachyon' -- a ray traced static image. - spin: (default: False); spins 3d plot, with number determining speed (requires mouse over plot) - events: if given, {'click':foo, 'mousemove':bar}; each time the user clicks, the function foo is called with a 2-tuple (x,y) where they clicked. Similarly for mousemove. This works for Sage 2d graphics and matplotlib figures. ANIMATIONS: - animations are by default encoded and displayed using an efficiently web-friendly format (currently webm, which is **not supported** by Safari or IE). - ``delay`` - integer (default: 20); delay in hundredths of a second between frames. - gif=False -- if you set gif=True, instead use an animated gif, which is much less efficient, but works on all browsers. You can also use options directly to the animate command, e.g., the figsize option below: a = animate([plot(sin(x + a), (x, 0, 2*pi)) for a in [0, pi/4, .., 2*pi]], figsize=6) show(a, delay=30) EXAMPLES: Some examples: show(2/3) show([1, 4/5, pi^2 + e], 1+pi) show(x^2, display=False) show(e, plot(sin)) Here's an example that illustrates creating a clickable image with events:: @interact def f0(fun=x*sin(x^2), mousemove='', click='(0,0)'): click = sage_eval(click) g = plot(fun, (x,0,5), zorder=0) + point(click, color='red', pointsize=100, zorder=10) ymax = g.ymax(); ymin = g.ymin() m = fun.derivative(x)(x=click[0]) b = fun(x=click[0]) - m*click[0] g += plot(m*x + b, (click[0]-1,click[0]+1), color='red', zorder=10) def h(p): f0.mousemove = p def c(p): f0(click=p) show(g, events={'click':c, 'mousemove':h}, svg=True, gridlines='major', ymin=ymin, ymax=ymax) """ # svg=True, d3=True, svg = kwds.get('svg',True) d3 = kwds.get('d3',True) display = kwds.get('display', True) for t in ['svg', 'd3', 'display']: if t in kwds: del kwds[t] import graphics def show0(obj, combine_all=False): # Either show the object and return None or # return a string of html to represent obj. if isinstance(obj, (Graphics, GraphicsArray, matplotlib.figure.Figure, matplotlib.axes.Axes, matplotlib.image.AxesImage)): show_2d_plot_using_matplotlib(obj, svg=svg, **kwds) elif isinstance(obj, Animation): show_animation(obj, **kwds) elif isinstance(obj, Graphics3d): if kwds.get('viewer') == 'tachyon': show_3d_plot_using_tachyon(obj, **kwds) else: salvus.threed(obj, **kwds) # graphics.show_3d_plot_using_threejs(obj, **kwds) elif isinstance(obj, (sage.graphs.graph.Graph, sage.graphs.digraph.DiGraph)): if d3: show_graph_using_d3(obj, **kwds) else: show(obj.plot(), **kwds) elif isinstance(obj, str): return obj elif isinstance(obj, (list, tuple)): v = [] for a in obj: b = show0(a) if b is not None: v.append(b) if combine_all: return ' '.join(v) s = ', '.join(v) if isinstance(obj, list): return '[%s]'%s else: return '(%s)'%s else: s = str(sage.misc.latex.latex(obj)) if '\\begin{tikzpicture}' in s: # special case -- mathjax has no support for tikz so we just immediately display it (as a png); this is # better than nothing. sage.misc.latex.latex.eval(s) return '' elif display: return "$\\displaystyle %s$"%s else: return "$%s$"%s s = show0(objs, combine_all=True) if s is not None: if display: salvus.html("<div align='center'>%s</div>"%cgi.escape(s)) else: salvus.html("<div>%s</div>"%cgi.escape(s))
