MaplePrimes - answers and comments on Question, Using POINTPLOT to plot multiple numeric data sets

display

The standard way of combining multiple plots in one is using display (from the plots package), see

?plots,display

plot can be used, as well, and a series of commands from the Statistics package.

Note the help menu applies the "display" command for plotting functional relationships, NOT numeric data.

I tried it anyway & did not get it to work on NUMERIC data.

NEED other suggestions!

All of the above

All of the above comments are valid. I have attached a worksheet that reads a data file with 5 columns of data and plot the 1st column against the rest. You can modify it for your own data as needed.

The data file looks like this. It is stored in my C:\temp\Maple directory. It is called rssi1.dat.

Numeric data

Where did you see in the help that "display" is for plotting functional relationships? I didn't see that in the ?plots,display help page.

Actually, all of Maple plot commands are for numerical data, and not for functional relationships. Even when, say, a plot command is used for plotting a function, then first this function is evaluated in series of points, getting "numeric data", and then this "numeric data" is plotted.

Now, why it didn't work when you tried it. You didn't provide an example in your original post, so I couldn't show you how to do that in that (unexisting) example.
