R-Plot is a Windows program for presenting measuring data as X-Y diagrams, bar charts or histograms. Optionally you can add error bars, best-fit curves, computed functions, images, text and simple graphic objects. The number of charts per sheet and objects per chart is in theory unlimited.

On the desktop, two windows are displayed (as shown on the right). In the left one the graphical output is displayed. The right one is intended for editing the plot. The sheet can be sent to any Windows printer, inserted into another application using the clipboard and/or exported as Encapsulated Postscript (EPS) for insertion as an image into LaTeX documents.

The following objects can be added to a chart:

• X and Y axes
  • Position: Left or right, resp. top or bottom or at any other position
  • Labeling: adjustable size and font
  • Tick marks: adjustable length, width and color
  • Scaling: linear, logarithmic and inverse
  • Grid: optional for X and/or Y
• Data curves
  • Axes: selectable
  • Measuring points: 12 selectable symbols, adjustable size and color
  • Connections: straight lines or spline function, adjustable line width and color
  • Error bars: separately selectable for X and Y, symmetric and asymmetric error values, adjustable line width and color
  • Data: either manual input or import in csv format


• Best-fit curves
  • Axes: selectable
  • Data curve: selectable
  • Approximation: straight line and polynomial
  • Scaling: linear, logarithmic and inverse

Installation

R-Plot is provided as executable Windows setup. You can install this version of the program under both 32-bit and 64-bit systems. The directory can be selected by the user, but strongly recommended is an installation to the system-dependent default location. To uninstall use the Windows control panel.
