VISUALISATION / GRAPHICS
20 May 2013
Codecogs has launched its new version of Formula Render (fxRender). After two years of refinement, the company says version three represents a major enhancement in speed, quality and usability.
fxRender is an Excel add-in that transforms formulas into graphical images, to provide a clear illustration of spreadsheet calculations. Codecogs says the tool solves a number of challenges including documenting calculations, finding errors in formulas and publishing equations to other applications and website.
Installing fxRender creates a new toolbar in Excel, with a simple interface and a variety of options to control the presentation of formulas. For example, it offer three main ways to represent formula variables by using normal Excel style cell references (e.g. 'A1'), cell names or associated labels, or values from referenced cells.
The last option is a great way to debug a formula and check the exact values being used in each part of a calculation. In all cases, the elements of the equation are presented in a standard mathematical form commonly seen in both textbooks and scientific papers.
These equations can be presented in a number of formats and styles, including a variety of fonts, font sizes, borders and background colour. By default, the equation will mimic the fonts and colours used by the Excel cell.
