I see this has been closed as "simple mistake ... or else it is easily found in the documentation." The question asks "But I don't get the result I want when I run the following code. What can I do to get it?" So this is not merely complaining that Mathematica doesn't work as OP thinks it should, but an actual request for assistance. Agree/disagree?
I want to draw a parametric equation with ± like the figure below:
But I don't get the result I want when I run the following code. What can I do to get it?
ParametricPlot[{x, ±x^2}, {x, 0, 1},
Mesh -> 30, PlotPoints -> 50, AxesOrigin -> {0, 0}]
In computing and typesetting, a soft hyphen (ISO 8859: 0xAD, Unicode U+00AD SOFT HYPHEN, HTML: ­ ­) or syllable hyphen (EBCDIC: 0xCA), abbreviated SHY, is a code point reserved in some coded character sets for the purpose of breaking words across lines by inserting visible hyphens. Two alternative ways of using the soft hyphen character for this purpose have emerged, depending on whether the encoded text will be broken into lines by its recipient, or has already been preformatted by its originator.
== Text to be formatted by the recipient ==
The use of SHY characters in text that will...
@MichaelHale We call it a "pipeline" but in reality it is almost never linear. It is more like a directed acyclic graph. For example, from a we compute b and c, then from c we compute d then from b and d we compute e, then from a and d we compute f then form f and e we compute the final result. A simple chain of functions won't work in practice.
Of course, in principle, I could bundle those intermediate results up into an association ... but it's likely that it'd be hard to stay organized that way. Plus, auto-complete doesn't work on association keys, annoying.
