Graph It in Action

Boots to BASIC.  Use CLOAD to load the desired plotting program from cassette or run it from disk if it has been converted.  There is no menu for choosing.

Bar Charts and Pie Graphs

Menu

Atari Graph It Bar Pie Menu

 

Bar Charts

Give the chart a title:

Atari Graph It Bar 1

 

Define the number of factors:

Atari Graph It Bar 2

 

Enter the column labels:

Atari Graph It Bar 3

 

Enter the values for each factor:

Atari Graph It Bar 4

 

See the result.  Chart using 1 factor (episode size in MB):

Atari Graph It Bar 5

 

Exiting the chart:

Atari Graph It Bar 6

 

See the result.  Chart using 2 factors (episode len in minutes and seconds):

Atari Graph It Bar 7

 

Pie Graphs

Entering the graph title:

Atari Graph It Pie 1

 

Setting the Pie slice labels:

Atari Graph It Pie 2

 

Setting the Pie slice values:

Atari Graph It Pie 3

 

Setting the graph sub title:

Atari Graph It Pie 4

 

See the result.  Graph for categorized episode lengths:

Atari Graph It Pie 5

 

Exiting the graph:

Atari Graph It Pie 6

 

Two Dimensional Plots

Plot splash banner:

Atari Graph It XY 1

 

Define the number of functions for the plot:

Atari Graph It XY 2

 

Enter the function(s) for the plot:

Atari Graph It XY 3

 

Choose the plot speed (plot resolution – faster is lower resolution):

Atari Graph It XY 4

 

Enter the limits for the function variables:

Atari Graph It XY 5

 

Specify auto scaling (in case it may plot beyond screen range):

Atari Graph It XY 6

 

Seeing the result:

Atari Graph It XY 7

 

Exiting menu:

Atari Graph It XY 8

 

Returning to graph (Do Not Exit):

Atari Graph It XY 9

 

Using the joystick to find values along the plot:

Atari Graph It XY 10

 

Polar Plots

The polar plot splash screen:

Atari Graph It Pol 1

 

Entering the X function:

Atari Graph It Pol 2

 

Entering the Y function:

Atari Graph It Pol 3

 

Entering the Theta values and increment:

Atari Graph It Pol 4

 

Choosing to auto scale or not:

Atari Graph It Pol 5

 

See the result.  Simple circle plot:

Atari Graph It Pol 6

 

Using the joystick to find values along the plot lines:

Atari Graph It Pol 7

 

Exit menu:

Atari Graph It Pol 8

 

Polar flower plot using Graph It (plot time = 2 minutes).  Function definition, parameter values, and result:

X=COS(1.5*T) * COS(T) and Y=COS(1.5*T)*SIN(T), with theta values of 0 to 13 in .1 increments.

Atari Graph It Pol 9 Flower

 

Same polar flower plotted using a Casio fx-9750G Plus (plot time = 20 seconds):

Atari Graph It Pol Casio

 

Same polar flower plotted using web based FooPlot (plot time = instantaneous):

Atari Graph It Pol Web Flower

 

Three Dimensional Plots

The three dimensional plot splash screen:

Atari Graph It XYZ 1

 

Defining the function:

Atari Graph It XYZ 2

 

Choosing the plot speed (plot resolution: fast is low resolution):

Atari Graph It XYZ 3

 

Defining the X values:

Atari Graph It XYZ 4

 

Defining the Y values:

Atari Graph It XYZ 5

 

Choosing to auto scale or not:

Atari Graph It XYZ 6

 

Defining the Z value limits:

Atari Graph It XYZ 7

 

Options to remove hidden plot lines and turning the display off during plot (roughly 30% increase in speed):

Atari Graph It XYZ 8

 

Plotting started:

Atari Graph It XYZ 9

Atari Graph It XYZ 10

 

Result:

Atari Graph It XYZ 11

 

Exit menu:

Atari Graph It XYZ 12

 

Same plot using FAST option (lower resolution, fewer plotted points):

Atari Graph It XYZ 13 Fast

 

Replotting and not removing hidden lines:

Atari Graph It XYZ 15

 

Result:

Atari Graph It XYZ 14 Slow No Remove

 

Files

Contents

Normally there are no files since the program ships on cassette.  Graph It, when converted to disk, uses Atari DOS 2.0.  The contents of the disk can be seen in this screenshot:

Atari Graph It Files

 

The files are:

  • CHARTPIE.BAS is Bar and Pie Chart program.
  • POLAR.BAS is the Polar plot program.
  • XY.BAS is the 2D plotting program.
  • XYZ.BAS is the 3D plotting program.

Printing

There is no provision for printing.

 

Instructions

You can find the manual in multiple locations on the internet.  Check the AtariMania site as one example.
