I’m working on integrating some additional metrics that are gathered outside of Piwik proper into a Piwik plugin, so my client can visit one site to view all the relevant data they wish to monitor. Obtaining and parsing this third-party data isn’t an issue, but the Piwik evolution graphing API seems to want a lot of additional data outside of the basic X increments and series of data. I’ve pored over as much of the sparse/outdated documentation as I can find, but I can’t seem to get a clear picture of the bare minimum data necessary to submit for Piwik to build an evolution graph.
Just creating a new Map and filling it with Tables seems to create numerous errors. I’ve had a bit more luck making API calls and emptying the data containers, studying the values, and replacing various pieces of data to get sort of what I’m looking for, like so:
$result = $data->getEmptyClone($keepFilters = false);
foreach($data->getDataTables() as $date => $dateTable){
foreach($dateTable->getRows() as $row){
$newTable = $dateTable->getEmptyClone($keepFilters = false);
$newTable->addRowFromSimpleArray(array(
‘label’ => “test”,
‘visits’ => 3
));
$newTable->addRowFromSimpleArray(array(
‘label’ => “test2”,
‘visits’ => 4
));
$result->addTable($newTable, $date);
}
}
But it feels like the slightest breeze will destroy everything. I get the impression that Piwik expects very specific labels for data, all pertaining to its own API - that it doesn’t want to play nicely with external data. I even tried embedding a Google chart into the plugin instead, but there’s no good place in the Piwik system to hook in the Google API.
All I want to be able to do is hook in my own data to build charts is Piwik. Is there something I’m missing?
