How can I add the options structure to the flot chart?
For example for changing the legend position I would need something like this:

$.plot($("#flotcontainer"),
            [
                {label:"data1", data:data1},
                {label:"data2", data:data2},
                {label:"data3", data:data3}
            ],
            options
        );

where options is:

 options = {
            legend:{         
                noColumns: 0,
                backgroundColor: "green",   
                position: pos
            }
        };

How it work the x-axis time? I don't know how to put the time. Furthermore, when I make a push in my api, the other values disappaer.

Thanks!

Would be nice to see that you add proper instructions...

I return same data as you used in the example, trying to push any data to be shown and it doesn't work...

Only time it works is if i copy paste values structure directly into the form...

for example, i push to mqtt server this data:

[{label: 'one', data: [[0,2],[1,3],[2,5]] }, { label: 'two', data: [[0,1.3],[1,3.5],[2,4]] }]

with key:

"something"

and i try to fetch it like this:

var new_data = datasources["datasource"];
if (new_data["topic"] == "mytopic/something")
{
return new_data["msg"];
}

And nothing....

If i put console.log there to identify what it returns, it works ok, it returns same "string" which works if i just statically past in the value field....

Even this would not work:

return "[{label: 'one', data: [[0,2],[1,3],[2,5]]}]";

but this would work:

[{label: 'one', data: [[0,2],[1,3],[2,5]]}]

Does this have the ability to be used with Dweet datasources? I can get it working fine with static data for the value, but it doesn't display anything when that is changed to a dweet source

Hi,
I really like those charts - but I´m looking for a way to use this with "historical data" coming from a JSON or CSV file.

Use case:
I have a URL that provides a JSON file that always has the latest 2 hours of temperatur data (including time stamps). I would like to get that charted when the dashboard is loaded.
Also, it should poll the JSON periodically to get the latest data and update the chart with it.

Freeboard is great - but it really focusses on real time data and I would like some historical data and can´t get that to work ...

An example how to do that would be highly appreciated, sorry if that seems a stupid request, but I can´t get it to work. I´m getting confused by your sample for line chart that has as value the following:
"value": "[[[1,2],[2,3],[4,5]]]"
I would have expected the value to be [1,2],[2,3],[4,5] ?

Thanks - MacSass
