What is Datascape
-----------------
Datascape is a 2D linear and logrithm data plot and browse tool for Win32.
It offers many powerful features for graph presentation of scientific data
by infinite zooming and various plot styles. It can also plot a mathematical
expression dynamically.
You can zoom in on any region of the graph by drawing a box. Start at the
upper left corner of the region you wish to view in more detail, and drag
downwards and to the right. Dragging upwards instead allows you to zoom
out. Clicking on the "Autoscale" button on the toolbar brings all data
within range.
Scroll the data on the display using the left, right, up and down arrow
keys on the keyboard. Press CONTROL key to accelerate, and press SHIFT key
to constrain the w/h ratio.
Datascape can also serve as a good data acquisition tool working with GPIB
(National Instruments) or RS232. It can operate spectrometer, lock-in
amplifier, photon counter, I-V unit etc. Contact the author for additional
information.

expressions are entered as text. Datascape will determine if what you
entered is a legal formula string. The available functions are:
sin (x) - Sine of x
cos (x) - Cosine of x
tan (x) - Tangent of x
sinh(x) - Hyperbolic sine of x
cosh(x) - Hyperbolic cosine of x
tanh(x) - Hyperbolic tangent of x
asin(x) - Arc sine of x
acos(x) - Arc cosine of x
atan(x) - Arc tangent of x
abs (x) - Absolute value of x
ln (x) - Logarithm of x. Base e
log10(x) - Logarithm of x. Base 10
exp (x) - e raised to the power of x
pow10(x) - raise x to the 10th power
sqr (x) - Square of x
sqrt(x) - square root of x
round(x) - round to the nearest whole number
trunk(x) - return the whole part of a number
