Hm, this seems like a bug. Would you mind entering a bug report here so I don’t forget about it:

Oh yes, this is easier! :-)

But I tried to find out the best way to create a chart with bars.

I use the following statement to declare the data:

{data: [[0,28], [0,28]],label: “label goes here”,bars: {show: true } },

I think it is a little bit redundant to specify [0,28] twice, but if I try something like
{data: [[0,28]],label: “label goes here”,bars: {show: true } },
only the legend is shown, but no bars. What am I doing wrong?

(maybe it is a stupid question because it works if I use the first statement, but it seems to me that even the bars are painted twice, so the colors (originally pastel colors) are much darker.

Best regards!

The easiest way to disable ticks is to specify an empty ticks array:

xaxis: { ticks: [] }
yaxis: { ticks: [] }

I’ve explained this in the API documentation now. noTicks is a bit weird because it uses a heuristic instead of being exact. Hope this helps. :-)

Nice tool! I saw it yesterday on del.icio.us and just tried it out. I played a little bit around with it and got that (very simple):

One question:
I tried to format the legend with
{
yaxis: { noTicks: 0 },
xaxis: { noTicks: 0 }}
But this didn’t work properly (nothing could be seen).
I fixed it using a TickerFormatter like
{
yaxis: { tickFormatter: gettick },
xaxis: { noTicks: 0 }}
with
function gettick(val) {
return “”;
}

The workaround is simple, but, however, it is a little bit strange.

But I like the tool! :-)

Best regards!

Hmmm… I’ve been meaning to play around with mootools more… might have to port this over to that.

Great tool! The zooming and selection features seem to work very smoothly. Especially the last example is quite impressive.

Now that is some sweet charting goodness. There are too many good bits in all the frameworks. I want them all in one :D

Err… substitute “it” for “at” in the parenthesis.

@Andy: Not to continue this needlessly, but I find the need to correct your correction. In Danish, “Flot” does mean “pretty” (I don’t agree with atlithorn’s perception that it’s cool, although I see where he’s going it), and since Ole Laursen is Danish, I think it’s safe to assume that’s the intention. In Swedish however, it is called “flott”. So you are yourself wrong :-)

This is going to be great for custom analytics, I’ve been making my charts and graphs with HTML/CSS. Nice work, Ole.

@JÃ¶rn Zaefferer: Ah, yes. I missed that. Anyway, it would nice if You could mouse-over the dots and it would display the value.

Congratulations Ole, I was long waiting for a plotting library in jQuery and you far exceeded what I was expecting:-) Moreover I really needed something like this by this weekend: great timing also! I’ll drop by your office before Christmas…

@Andy: Check the Zooming with overview demo, which allows you to select an area in the overview to zoom in on that area in the main diagram.

@atlithorn: Actually, You’re wrong. You’re thinking of ‘flott’.

Either way, this plotting plugin looks rather good. Would be great with some interaction, though.
