Hi Peter,
How would I make the spaces differ between the ticks for both axises,

I'm gonna $dataX and $dataY arrays of 5 elements, I want to make the cell on 5x5 the biggest ... and 1x1 cell the smallest.

it will be helpful if there is an example I can look at.

Thank you

Hi Yorssef,

First, create an axis with no label/tick. Then use Axis.addLabel to add labels or ticks to anywhere you want.

For example, to add ticks at x = 1, 3, 7, 16, 21, the code is (in PHP):

#assume you want to the x-axis scale to be 1 - 21
$c->xAxis->setLinearScale2(1, 21, array());

$xTicks = array(1, 3, 7, 16, 21);
for ($i = 0; $i < count($xTicks); ++$i)
   $c->xAxis->addLabel($i, $i);

The same can be applied to the y-axis.

Hope this can help.

Regards
Peter Kwan

Peter,
thank you for your suggestion, it worked like a charm.

I only had to change the addLabel first argument to $xTicks[$i] instead of $i:

$xTicks = array(1, 3, 7, 16, 21);
for ($i = 0; $i < count($xTicks); ++$i)
   $c->xAxis->addLabel($xTicks[$i], $i);

best regards
