labels, e.g.
$.plot("#placeholder", data, { xaxis: { mode: "categories" } });
$.plot("#placeholder", data, { xaxis: { mode: "categories" } });
By default, the labels are ordered as they are met in the data series. If you
need a different ordering, you can specify "categories" on the axis options
and list the categories there:
xaxis: {
mode: "categories",
categories: ["February", "March", "April"]
}
xaxis: {
mode: "categories",
categories: ["February", "March", "April"]
}
If you need to customize the distances between the categories, you can specify
"categories" as an object mapping labels to values
xaxis: {
mode: "categories",
categories: { "February": 1, "March": 3, "April": 4 }
}
xaxis: {
mode: "categories",
categories: { "February": 1, "March": 3, "April": 4 }

from the max value plus 1 (with a spacing of 1 between each).

upperCap: null or "-" or function,
lowerCap: null or "-" or function,
color: null or color,
radius: null or number
},
yerr: { same options as xerr }

Each data point array is expected to be of the type:
"x" [ x, y, xerr ]
"y" [ x, y, yerr ]
"xy" [ x, y, xerr, yerr ]
"x" [ x, y, xerr ]
"y" [ x, y, yerr ]
"xy" [ x, y, xerr, yerr ]
Where xerr becomes xerr_lower,xerr_upper for the asymmetric error case, and
equivalently for yerr. Eg., a datapoint for the "xy" case with symmetric
error-bars on X and asymmetric on Y would be:
[ x, y, xerr, yerr_lower, yerr_upper ]
[ x, y, xerr, yerr_lower, yerr_upper ]
By default no end caps are drawn. Setting upperCap and/or lowerCap to "-" will
draw a small cap perpendicular to the error bar. They can also be set to a
user-defined drawing function, with (ctx, x, y, radius) as parameters, as eg.
function drawSemiCircle( ctx, x, y, radius ) {
ctx.beginPath();
ctx.arc( x, y, radius, 0, Math.PI, false );
ctx.moveTo( x - radius, y );
ctx.lineTo( x + radius, y );

// When combining smaller slices into an 'other' slice, we need to

// it starts out false, and is set to true after the first call to
// processDatapoints.
// Unfortunately this turns future setData calls into no-ops; they
// call processDatapoints, the flag is true, and nothing happens.
// To fix this we'll set the flag back to false here in draw, when
// all series have been processed, so the next sequence of calls to
// processDatapoints once again starts out with a slice-combine.

// WARNING: HACK! REWRITE THIS CODE AS SOON AS POSSIBLE!
// When combining smaller slices into an 'other' slice, we need to
// add a new series. Since Flot gives plugins no way to modify the
// list of series, the pie plugin uses a hack where the first call
// to processDatapoints results in a call to setData with the new
// list of series, then subsequent processDatapoints do nothing.
// The plugin-global 'processed' flag is used to control this hack;
// it starts out false, and is set to true after the first call to
// processDatapoints.
// Unfortunately this turns future setData calls into no-ops; they
// call processDatapoints, the flag is true, and nothing happens.
// To fix this we'll set the flag back to false here in draw, when
// all series have been processed, so the next sequence of calls to
// processDatapoints once again starts out with a slice-combine.
// This is really a hack; in 0.9 we need to give plugins a proper
// way to modify series before any processing begins.
