Hi.

I'm currently reworking some code for a personal project which uses pChart 1.27. How easy is it to upgrade to version 2?

Rewrite code, but for pChart 2. Only then you'll get a normal result.

Hi mrbobdobolina,

The coding philosophy has deeply changed with this new version. You'll have to rewrite all your code to adapt it. Hopefully, I strongly believe that it will be quite easy because of the function naming and the new help interface.

I'll publish a note on the wiki explaining how to plan an upgrade.

Kind regards,
JD.

I've downloaded the code and given it a whirl.

I really like the way everything is laid out now. It's definitely easier to use, but it will take some time to port things over. I managed to get my Pie Charts switched over, but i'm having some trouble with the bar charts.

Hopefully I'll have time later this week to play around with some of the other things I need to do.

HI, I'm in the process of upgrading ...

I'm stuck with the new drawscale function -
My 1.27.d version is below - but I can't understand the format of the new function - even from the documentation - could anyone give me some pointers ?
thanks


this is the 1.27.d version of my drawscale function( $scaleskip is a pre set variable)
$Test->drawScale($DataSet->GetData(),SCALE_NORMAL,0,0,0,TRUE,0,2,TRUE,$scale_skip);

There is no special tweak in your call :
Code:
$Test->drawScale($DataSet->GetData(),SCALE_NORMAL,0,0,0,TRUE,0,2,TRUE,$scale_skip);


This should be translated to something like :
Code:
$Settings = array("LabelSkip"=>$scale_skip);
$myPicture->drawScale($Settings);


..assuming that your pImage object is called $myPicture.

Thanks JD,

This makes sense to me and I've tried it - but for some reason it's not working ...
I'll play around with a bit more and see if I can find the problem


regards
