Dear clinkadink,
I did a copy and paste, But no bar only a line graph.
So I think it has to be something else
Thanks anyway.

How can I change the popup graph from line to bar 3.4.1
I tried:

blocks['graph_2447'] = {
devices: [2447],
title: 'Zonnestroom',
graph: ["bar"],
datasetColors: ['yellow'],
legend: {
'v': 'Zonnestroom',
}
}

Please help.
What am I doing wrong?

Is www.dashticz.nl down???
Garbage not working anymore
