More information:
Plot.bas can be used to plot numerical data. Features include:
  • cartesian axes (x and y-axes are not fixed)
  • include to show origin yes or no
  • include to show gridlines yes or no
  • add titles for x- and y-axis
  • plotting types are 'point', 'connected line' and 'bar'
  • different traces can be plot in the same drawing pane
  • 10 different colors to plot the traces
  • scientific notation is used when differences in X and Y are bigger then 100000 or smaller than 0.00001.

A sample application that demonstrates how to use the module is included. - scientific notation will be shown under an angle when more than 10 lables needs to be shown on the x-axis (to avoid overlapping lables) Features from the form showing the plot: - SHIFT + left mouse gives zoom function - right mouse click gives value of (X,Y) - double left click draws the starting values Three demo traces are added, they can be shown with the features as described above.
