How can I define a Step-Wise function in Mathematica (Not using Heaviside Step Function)? Indeed, that's how you can use it. |

Exporting large numbers to a text file You can use NumberForm with the option ExponentFunction: NumberForm[123456.789, {20, 3}, ExponentFunction -> (Null &)] |

How can I invert the colors in a color bar Try replacing colorbar[valrange, cf] with colorbar[valrange, ColorData[cf][1 - #] &] at the end of your example. |

Pretty way to group elements at odd and even positions @Mr.Wizard Ha, I've just seen now that in the docs for Span it says m[[i;;j;;k]] is equivalent to Take[m,{i,j,k}]. Well, let's say that mine is more readable for novice users. |

Coloring Points in a Plot, based on their position in the list Maybe it is worth pregenerating all the solutions of your ODE and use those in your Manipulate function. Take a look also at Mr.Wizard's solution to speed up rendering of ListPolarPlot. |

Coloring Points in a Plot, based on their position in the list @Mr.Wizard I fully agree with your comment and I support solutions based on Graphics primitives. Since the question was based on a ListPolarPlot I gave a solution that holds for this function. |

Coloring Points in a Plot, based on their position in the list BTW, instead of typing Transpose[position][[1]] you can get the same result with position[[All, 1]]. |

Mathematica color schemes for the colorblind @m_goldberg What I meant is that the point of a color scheme for people with color-impaired vision is to distinguish the colors of the octagons, not to read the text. I've added another version of the same picture, maybe it helps. |

Mathematica color schemes for the colorblind @jenson I fully agree, data should be distinguished by colors, symbols and line styles to be always easily readable. |

Mathematica color schemes for the colorblind @m_goldberg An answer to your first question: the pictures above are not the Mathematica default color scheme, they are taken from the docs they I linked in my answer. |

Mathematica color schemes for the colorblind @jenson The choice of colors is described in section 6 of the linked pdf. See also the new picture added to my answer. |

Mathematica color schemes for the colorblind @m_goldberg As long as you can distinguish the colors of the octagons, you're fine. The black text inside the lower left octagon is barely readable because of the small difference in contrast. |

Separating positive and negative numbers into two arrays @belisarius Yep, in this form it works only under the assumption that the list c contains both positive and negative numbers. |

Strange behavior of PlotMarkers with ListLinePlot[] and InterpolationOrder->0 Literally from the documentation for Mesh: Full mesh divisions between regular data points. |

How to add a common color legend to a grid of density plots? I don't have Mathematica 9 to test it, but shouldn't this also work? GraphicsGrid[{{plots[[1]], plots[[2]]}, {plots[[3]],
plots[[4]]}, {legend, SpanFromLeft}}, Alignment -> Center,
ImageSize -> 300] |
