PalmPlot 1.01

PalmPlot Publisher's Description

PalmPlot was inspired by the old Casio FX graphing calculator I used to have when I was in college... It lets you:

  • Evaluate mathematical expressions - well, it is not just a calculator! Supports hyperbolic, logarithmic, exponential, trigonometric functions, variables and affectations, derivatives, integrals and finite sums, etc.
  • Plot graphs of functions, in rectangular and polar coordinates, or plot parametric curves.
  • Display tables of values for functions.
  • Numerically solve equations.
  • Perform 1-var / 2-vars statistics computations with editable data, histogram and scatter plot.

    Special features:Simultaneous color plots, runs without mathlib, several number formats available, 26 variables, dozens of built-in functions, 3 customizable keys, searchable functions reference.

And registered users can obtain the source code some of the HB++ classes used for this project - including the expression parser and stack machine - as long as they don't use it to develop... competitors to PalmPlot ;-)

    PalmPlot 1.01 new features:
  • Added a new row of keys, three of which can be customized in a new "Custom Keys" dialog, the others being a new "soft key" and ",".
  • Added the intg and diff functions to compute approximations of integrals and derivatives ; and the sum function to compute finite sums.
  • Added a few physical constants and a "pi" button in the trig section.
  • Added support for 1-var or 2-var statistics (linear regression), with a data table editor and histogram/scatter plot.
  • Added help text in all the dialog boxes, and a searchable reference list of all the functions.
  • Fixed a bug in number formatting occuring with several locales.
  • Changed the way the range is specified for parametric plots. Instead of specifying a start, end, and step values for the parameter T, a start, end, and number of steps has to be specified.
  • Added a grid option and automatic scaling of data plots in the plot options.
