Hi,

In my yearly weather graph I have a slight problem that it seems the last value (which is a null) is not drawn properly. From the graph it looks like only 11 values are there (the marker of February isn't on the grid).

When I replace the nulls with zero's it does draw the line complete and all markers are on the correct position.

It can be seen on: io-node.net/weatherstation/index.php?action=year

Regards,

Stephan

Hi there,

That's correct behaviour. null represents "no data" which is not necessarily the same as zero. To convert them you can use the Number function:

var num = Number(num);

Or perhaps this:

var num = num || 0;
