Set different line format for a graph with more than one serie with pChart

I am actually using the pChart PHP library for generate graphs.

I wanna know if it's possible to give a different line format for a graph with multiple series.

I need a line with for example 3px of width but other line with 1px of width. Is that pos开发者_开发百科sible?

In the official documentation only appears a function that give format to the lines of all series:

Thanks a lot.

I found the solution: it's possible to add series after draw each one. It's possible to add and remove series in order to make that trick.

You can do it with the function setSerieWeight():

$oData->addPoints($line1, 'serie1');
$oData->setSerieWeight('serie1', 1);

$oData->addPoints($line2, 'serie2');
$oData->setSerieWeight('serie2', 2);

$oData->addPoints($line3, 'serie3');
$oData->setSerieWeight('serie3', 3);

You can use other functions to change a serie format, like:

setPalette('serie', ['R' => 100, 'G' => 0, 'B' => 255])

to change color of a single serie.
