I remember seeing an app that has a canvas, and on it you put individual 'sheets' or tables. You can reference between them as normal, drag and drop them around. The screenshots _may_ have shown math being entered too, I can't recall. Because my calculations are made up of many mini-calculations this seems a much better idea than the normal Excel style of multiple tables on one sheet, as adding a row doesn't... - Source: Hacker News / 6 days ago

I don't personally use it, but you might find Blockpad interesting https://blockpad.net/. - Source: Hacker News / over 1 year ago

In that space, https://blockpad.net/ is interesting also. - Source: Hacker News / over 1 year ago

I work at Blockpad, and we have a lot of structural engineering customers that love it. It's sort of like Mathcad+Excel, inside of Word. Source: almost 2 years ago

For engineers Blockpad (http://blockpad.net) is making a good case for itself as an Excel replacement. - Source: Hacker News / over 2 years ago

To some extent it extends the concept of tasks which only can be reasonably executed after the completion of other ones (though results of branches eventually may join each other) and offers an additional assisting birds' eye visual of projects. So far, I'm aware about the documentation on worg interfacing org-taskjuggler and taskjuggler, as well as a video tutorial interfacing gnuplot instead. Source: about 1 year ago

Gnuplot is a program to plot diagrams. The Commands issued to use it don't change regardless if it is used in Linux/Windows/MacOS and it comes with less dependencies than a Spread sheet, or a statistics program. This is why I started to Become comfortable with it, and venture out some of its features. Here, "conditional plot" referred to "the diagram only displays a Thing/uses a pixel if the value in the table... Source: about 1 year ago

Or, does drawing diagrams refers to plotting data, but neither using matplotlib, nor gnuplot (export to .svg, .pdf, .png; pstricks, tikz to mention a few options)? Source: over 1 year ago

There may the occasion you actually need the data from a publication, and want to plot them altogether with data newly collected data in one diagram in common. An overlay, though possible, can become tricky (scaling, centering, alignment, etc.) and plotting all data in a diagram generated from scratch (gnuplot/octave, matplotlib, Origin, ...) exported as an illustration in the usual formats (.pdf/.png), or...

Have you looked at the graphing capabilities of Octave or Gnuplot? Gnuplot in particular has a lot of options, and a GUI for those who want it. Source: over 1 year ago
