title: plotting negative numbers with flot / jquery
body: <p>I know Im missing something retarded here... All Im trying to do is graph f(x) = 2500 for a range of x from -75 to 75. This should make a horizontal line. Right now, I think its a misunderstanding on my part of some specifics of arrays. It starts at 0 and goes to 75 fine, it does not graph lower than 0. (I get half the line)</p>
  
  <pre><code>for(x = -75; x&lt;75; x++)
  {
      a_const[x] = [x, 2250];
  }
  </code></pre>
  
  <p>Im about certain the problem is there. Heres my .plot function, just to be sure.</p>
  
  <pre><code>$.plot(
          $("#mydiv"), 
          [
              //{label : "f(x) = x^2", data : a_exp},
              //{label : "f(x) = sqrt(x)", data : a_sqroot},
              //{label : "f(x) = 3root(x)", data : a_cuberoot}
              {label: "constant", data : a_const}
  
          ],
          {
              //yaxis: {min:-5000},
              xaxis: {min:-75},
              yaxis: {min:-1000},
              yaxis: {max:4000},
              grid: {hoverable:true, clickable:true },
              series: { points: {show:true}, lines:{show:true}}
  
          }
      );
  </code></pre>
