i have the followign code;
<?php
function imp($char,$tag){
foreach($char as $key=>$value){
$char[$key] = $value;
}
$char = implode($tag,$char);
return $char;
}
$sql = "SELECT * FROM tests WHERE member_id=1 ORDER BY ID ASC LIMIT
0,3";
$query = mysql_query($sql);
while($row = mysql_fetch_array($query)){
//$date[] = $row[date];
$day[] = $row[day];
$test14[] = $row[test14];
}
?>
<img src="http://chart.apis.google.com/chart?

&chls=2

&chs=300x260

&chf=bg,s,FFFFFF00
&chco=D5DF3D
&chm=B,D5DF3D44,0,1,0" />
this pulls my info from data base then draws the chart.
but for the example above i have manually inputed my chart data.
here is link to chart;
http://www.myreeftests.com/chart_test.php
my problem is this;
the points arnt VERY accurate, i will probably only show upto a
maximum of 4 results.
if i echo;
<? echo imp($test14,",")?>
i get these results; 26,25,27,25
can i make the y axis automatically scale according to the results?
any help would be appreciated.
