Post subject:  combine drawSplineChart and drawFilledSplineChart in a chart
Hi,
first I wanna say, I'm really impressed by the powerfull functions after using pChart since 24 hours yet.
It's amazingly easy to use and the documentation is really good.

But I have two questions

First, is it possible to define a drawing method for one data-series and another method for the next series in one chart?
I would like to use a spline in front of a filled spline for my two series.

Second, how to set the distance between y-axis values and the axis name?
Would be nice to manipulate it if the auto/default space is perceived to small.

thanks in advance

Hi,

Yes, it is possible: the idea is to define the series :
Code:
$MyData->addPoints(array(30,24,32),"This year");
$MyData->addPoints(array(28,20,27),"Last year");

Then hide one serie and draw a 1st chart :
Code:
$MyData->setSerieDrawable("Last year",FALSE);
$myPicture->drawFilledSplineChart();

Then hide the 1st serie and re-activate the second one :
Code:
$MyData->setSerieDrawable("This year",FALSE);
$MyData->setSerieDrawable("Last year",TRUE);
$myPicture->drawSplineChart();


You can find an example here : http://wiki.pchart.net/doc.combo.charts.html.

There is no option to add some extra spacing between the axis values and the axis name, I'll add this to the todo list.

Kind regards,
JD.

I had browsed the combocharts already, but I didn't realize that it is what I'm looking for

thanks for your quick response JD,

by the way - please think also about axis-name free 360°-rotation
