As an example, SVGs with +missing information from header or with unsupported content, may lead to +failure in generating the temporary image. Temporary images are required +mostly on extracting content from SVGs, but this is also where the x/y +offsets are extracted for each image which will be added.

Set "errorbars" inside +the points series to the axis name over which there will be error values in +your data array (*even* if you do not intend to plot them later, by setting +"show: null" on xerr/yerr). + +The plugin supports these options: + + series: { + points: { + errorbars: "x" or "y" or "xy", + xerr: { + show: null/false or true, + asymmetric: null/false or true, + 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 ] + +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 ] + +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 ); + ctx.stroke(); + } + +Color and radius both default to the same ones of the points series if not +set. The independent radius parameter on xerr/yerr is useful for the case when +we may want to add error-bars to a line, without showing the interconnecting +points (with radius: 0), and still showing end caps on the error-bars. +shadowSize and lineWidth are derived as well from the points series. + +*/ + +(function ($) { + var options = { + series: { + points: { + errorbars: null, //should be 'x', 'y' or 'xy' + xerr: {err: 'x', show: null, asymmetric: null, upperCap: null, lowerCap: null, color: null, radius: null}, + yerr: {err: 'y', show: null, asymmetric: null, upperCap: null, lowerCap: null, color: null, radius: null} + } + } + }; + + function processRawData(plot, series, data, datapoints) { + if (!series.points.errorbars) { + return; + } + + // x,y values + var format = [ + { x: true, number: true, required: true }, + { y: true, number: true, required: true } + ]; + + var errors = series.points.errorbars; + // error bars - first X then Y + if (errors === 'x' || errors === 'xy') { + // lower / upper error + if (series.points.xerr.asymmetric) { + format.push({ x: true, number: true, required: true }); + format.push({ x: true, number: true, required: true }); + } else { + format.push({ x: true, number: true, required: true }); + } + } + if (errors === 'y' || errors === 'xy') { + // lower / upper error + if (series.points.yerr.asymmetric) { + format.push({ y: true, number: true, required: true }); + format.push({ y: true, number: true, required: true }); + } else { + format.push({ y: true, number: true, required: true }); + } + } + datapoints.format = format; + } + + function parseErrors(series, i) { + var points = series.datapoints.points; + + // read errors from points array + var exl = null, + exu = null, + eyl = null, + eyu = null; + var xerr = series.points.xerr, + yerr = series.points.yerr; + + var eb = series.points.errorbars; + // error bars - first X + if (eb === 'x' || eb === 'xy') { + if (xerr.asymmetric) { + exl = points[i + 2]; + exu = points[i + 3]; + if (eb === 'xy') { + if (yerr.asymmetric) { + eyl = points[i + 4]; + eyu = points[i + 5]; + } else { + eyl = points[i + 4]; + } + } + } else { + exl = points[i + 2]; + if (eb === 'xy') { + if (yerr.asymmetric) { + eyl = points[i + 3]; + eyu = points[i + 4]; + } else { + eyl = points[i + 3]; + } + } + } + // only Y + } else { + if (eb === 'y') { + if (yerr.asymmetric) { + eyl = points[i + 2]; + eyu = points[i + 3]; + } else { + eyl = points[i + 2]; + } + } + } + + // symmetric errors?

The plugin defines plot.zoom({ center }), plot.zoomOut() and +plot.pan( offset ) so you easily can add custom controls. It also fires +"plotpan" and "plotzoom" events, useful for synchronizing plots. + +The plugin supports these options: +```js + zoom: { + interactive: false, + active: false, + amount: 1.5 // 2 = 200% (zoom in), 0.5 = 50% (zoom out) + } + + pan: { + interactive: false, + active: false, + cursor: "move", // CSS mouse cursor value used when dragging, e.g. "pointer" + frameRate: 60, + mode: "smart" // enable smart pan mode + } + + xaxis: { + axisZoom: true, //zoom axis when mouse over it is allowed + plotZoom: true, //zoom axis is allowed for plot zoom + axisPan: true, //pan axis when mouse over it is allowed + plotPan: true, //pan axis is allowed for plot pan + panRange: [undefined, undefined], // no limit on pan range, or [min, max] in axis units + zoomRange: [undefined, undefined], // no limit on zoom range, or [closest zoom, furthest zoom] in axis units + } + + yaxis: { + axisZoom: true, //zoom axis when mouse over it is allowed + plotZoom: true, //zoom axis is allowed for plot zoom + axisPan: true, //pan axis when mouse over it is allowed + plotPan: true //pan axis is allowed for plot pan + panRange: [undefined, undefined], // no limit on pan range, or [min, max] in axis units + zoomRange: [undefined, undefined], // no limit on zoom range, or [closest zoom, furthest zoom] in axis units + } +``` +**interactive** enables the built-in drag/click behaviour. If you enable +interactive for pan, then you'll have a basic plot that supports moving +around; the same for zoom. + +**active** is true after a touch tap on plot. This enables plot navigation. +Once activated, zoom and pan cannot be deactivated. When the plot becomes active, +"plotactivated" event is triggered. + +**amount** specifies the default amount to zoom in (so 1.5 = 150%) relative to +the current viewport. + +**cursor** is a standard CSS mouse cursor string used for visual feedback to the +user when dragging. + +**frameRate** specifies the maximum number of times per second the plot will +update itself while the user is panning around on it (set to null to disable +intermediate pans, the plot will then not update until the mouse button is +released). + +**mode** a string specifies the pan mode for mouse interaction. Accepted values: +'manual': no pan hint or direction snapping; +'smart': The graph shows pan hint bar and the pan movement will snap +to one direction when the drag direction is close to it; +'smartLock'. The graph shows pan hint bar and the pan movement will always +snap to a direction that the drag diorection started with. + +Example API usage: +```js + plot = $.plot(...); + + // zoom default amount in on the pixel ( 10, 20 ) + plot.zoom({ center: { left: 10, top: 20 } }); + + // zoom out again + plot.zoomOut({ center: { left: 10, top: 20 } }); + + // zoom 200% in on the pixel (10, 20) + plot.zoom({ amount: 2, center: { left: 10, top: 20 } }); + + // pan 100 pixels to the left (changing x-range in a positive way) and 20 down + plot.pan({ left: -100, top: 20 }) +``` + +Here, "center" specifies where the center of the zooming should happen. Note +that this is defined in pixel space, not the space of the data points (you can +use the p2c helpers on the axes in Flot to help you convert between these). + +**amount** is the amount to zoom the viewport relative to the current range, so +1 is 100% (i.e. no change), 1.5 is 150% (zoom in), 0.7 is 70% (zoom out). You +can set the default in the options. +*/ + +/* eslint-enable */ +(function($) { + 'use strict'; + + var options = { + zoom: { + interactive: false, + active: false, + amount: 1.5 // how much to zoom relative to current position, 2 = 200% (zoom in), 0.5 = 50% (zoom out) + }, + pan: { + interactive: false, + active: false, + cursor: "move", + frameRate: 60, + mode: 'smart' + }, + recenter: { + interactive: true + }, + xaxis: { + axisZoom: true, //zoom axis when mouse over it is allowed + plotZoom: true, //zoom axis is allowed for plot zoom + axisPan: true, //pan axis when mouse over it is allowed + plotPan: true, //pan axis is allowed for plot pan + panRange: [undefined, undefined], // no limit on pan range, or [min, max] in axis units + zoomRange: [undefined, undefined] // no limit on zoom range, or [closest zoom, furthest zoom] in axis units + }, + yaxis: { + axisZoom: true, + plotZoom: true, + axisPan: true, + plotPan: true, + panRange: [undefined, undefined], // no limit on pan range, or [min, max] in axis units + zoomRange: [undefined, undefined] // no limit on zoom range, or [closest zoom, furthest zoom] in axis units + } + };

For "xy", the selection becomes a rectangle where both ranges can be +specified. "color" is color of the selection (if you need to change the color +later on, you can get to it with plot.getOptions().selection.color). "shape" +is the shape of the corners of the selection. + +The way how the selection is visualized, can be changed by using the option +"visualization". Flot currently supports two modes: "focus" and "fill". The +option "focus" draws a colored bezel around the selected area while keeping +the selected area clear. The option "fill" highlights (i.e., fills) the +selected area with a colored highlight. + +There are optional selection decorations (handles) that are rendered with the +"focus" visualization option. The selection decoration is rendered by default +but can be turned off by setting displaySelectionDecorations to false. + +"minSize" is the minimum size a selection can be in pixels. This value can +be customized to determine the smallest size a selection can be and still +have the selection rectangle be displayed. When customizing this value, the +fact that it refers to pixels, not axis units must be taken into account. +Thus, for example, if there is a bar graph in time mode with BarWidth set to 1 +minute, setting "minSize" to 1 will not make the minimum selection size 1 +minute, but rather 1 pixel. Note also that setting "minSize" to 0 will prevent +"plotunselected" events from being fired when the user clicks the mouse without +dragging. + +When selection support is enabled, a "plotselected" event will be emitted on +the DOM element you passed into the plot function.
