#10 drawGrid problems with scatter

[Dylan Nelson]

When doing scatter plots with autoscaling (no calls to setFixedScale) drawGrid calculates for vertical lines wrong. It uses something related to

$ColCount = $this->DataCount;

a fix is instead, right above the for($i=1;$i<=$ColCount;$i++) line, use:

$ColCount = floor( ($this->GArea_X2 - $this->GArea_X1) / $this->DivisionWidth );

Can see the effect and result in the documentation scatterplot example if you remove the setFixedScale command.

I've added your fix in my staging box. This will be visible in the next minor.

Many thanks..!

The fix in 1.27d is incomplete, it should be:

/* Vertical lines */
if ( $this->GAreaXOffset == 0 )

$XPos = $this->GArea_X1 + $this->DivisionWidth + $this->GAreaXOffset;

else

$XPos = $this->GArea_X1 + $this->GAreaXOffset;

$ColCount = floor( ($this->GArea_X2 - $this->GArea_X1) / $this->DivisionWidth );
