      <itunes:summary>&lt;p&gt;1) Your X and G are tables.&amp;nbsp; ScatterPlot needs Vectors or lists.&amp;nbsp; I'm surprised you don't get an &amp;quot;invalid input&amp;quot; error message.&lt;br /&gt;
You might try&lt;/p&gt;
&lt;pre&gt;
&amp;gt; ScatterPlot(convert(X,list), convert(G,list));
&lt;/pre&gt;
&lt;p&gt;2) To restrict a plot P to a certain window, x from a to b and y from c to d (where a,b,c,d are real constants):&lt;/p&gt;
&lt;pre&gt;
&amp;gt; plots[display](P, view=[a..b, c..d]); 
&lt;/pre&gt;

      <itunes:summary>thanks Robert,

I fixed the table to list issue but I still don't see the difference between the 2. the problem that I still have the computer doesn't recognize the ScatterPlot command even when I use the with(Statistics)? any thoughts about that?

thanks</itunes:summary>

      <itunes:summary>&lt;p&gt;Make sure you spelled it right.&amp;nbsp; Maple is case-sensitive.&amp;nbsp; &lt;/p&gt;

      <title>fsolve values</title>
      <link>http://www.mapleprimes.com/posts/37085-Scatterplots-And-Curve-Fitting?ref=Feed:MaplePrimes:scatterplots and curve fitting:Comments#comment65039</link>
      <itunes:summary>I've been working with fsolve and I'm having the following issue:

fsolve({dif_Fliq=((nFsol-nFliq)/(psi_sol-psi_liq)),dif_Fliq=dif_Fsol},{psi_sol=0.1..0.9,psi_liq=0.1..0.9});
              {psi_liq = 0.4447971078, psi_sol = 0.3459845910}

how do I get the value of psi_liq and psi_sol and assign them to a different variable without having to copy the whole thing? i.e. 

if I use the following command
assign(result_liq,psi_liq);
I get 

result_liq=psi_liq = 0.4447971078 not what I want result_liq = 0.4447971078

I also tried:

result_liq:=psi_liq and I ended up with the same result

any thought on how to do this?

thanks</itunes:summary>
