  Using ChartDirector in a Perl subroutine
Posted by Alex Zeng on Jul-22-2009 03:28

Dear All,

I'm new to Perl, and so my questions might seem a little out there, but please bear with me.

When I'm running sample scripts in ChartDirector with ActivePerl, I have to cd into the
scripts' working directory for everything to work. I was wondering if I can use ChartDirector
within a subroutine in my own .pm script. To run the .pm script, I have to put it in the same
directory as the shell.pl script and cd into the working directory on Command Prompt. Will I
still have to cd into ChartDirector's working directory to run the subroutine? If so, is there a
way to get into both the ChartDirector's working directory and the shell.pl 's working
directory at the same time?

Another question I had was that I'm trying to create a scatter plot with a pre-specified
(specified by me) number of X and Y ticks. That is, I want the scatter plot to have the
same size, and not autosize according to the data point that has the max xy coordinates.

Thanks in advance!
Alex

Please ignore the first question. I just tried it out and I guess as long as I reference to the
ChartDirector directory inside my .pm script, I don't need to cd into the working directory.

I still don't know the answer to my second question though.

Hi Alex,

You may use Axis.setLinearScale to set the scale manually. For example:

$c->xAxis()->setLinearScale(0, 100, 10);
$c->yAxis()->setLinearScale(30, 70, 5);

Hope this can help.

Regards

Peter,

Thanks for your reply. I haven't had a chance to try it yet, but I'll let you know once I do.
