Jupyter is easy once you have it installed (like installing Anaconda distribution and typing "jupyter notebook" on the command line. But that is already a high bar for non technical people. I am very interested in Grafoscopio to work out proof of concepts in Pharo, so that I can have a nice narrative structure. Coupled with gtExample and specific inspector presentations, this is a terrific thing. My current project involved a Glorp component and I'd like to showcase transactions within a Grafoscopio notebook. I'll tell you how it goes :-) Fossil is indeed a great vehicle for code and assets.

Re: [Pharo-users] Histogram for files dates and sizes

by Offray Vladimir Luna CÃ¡rdenas

Hi, Here is the improved version: As you can see, now I coded colored years functionality (I thought that colored histograms, following a criteria, would be supported by default, but I was unable to find any documentation or example about it). Two questions remain: * How can I add ticks in the X axis, so they correspond to a particular criteria? For example, a change in the year? * There is any way to make the RTLegend puts the color labels in a "matrix alike" fashion? So, for example, I would like to say that instead of having the default 1xn column of color labels, as now, I want them organized over a nxm matrix, so they suit better different graphical objects and layouts.

Re: [Pharo-users] Showcasing Pharo, Roassal and Grafoscopio at re:publica 2018

Hi Phil, Seems that some dependency related with GT-Examples and LibGit changed recently. On Mac/Linux installation was well until last week. I have had problems with LibGit in the past (which BTW, makes any install process really unpleasant), but I don't know if they're related with your issue. At that time the solution was to disable LibGit "developer profile" integration (which asked for a LibGit setup). Maybe you can try installing it before installing Grafoscopio, by following the instructions at [1], or if that doesn't work, maybe the folks at GT can help us with that. [1] https://github.com/feenkcom/gtoolkit Let me know how it goes.
