Copyright (c) 2007-2014 IOLA and Ole Laursen. Licensed under the MIT license. The plugin supports these options: crosshair: { mode: null or "x" or "y" or "xy" color: color lineWidth: number } Set the mode to one of "x", "y" or "xy". The "x" mode enables a vertical crosshair that lets you trace the values on the x axis, "y" enables a horizontal crosshair and "xy" enables them both. "color" is the color of the crosshair (default is "rgba(170, 0, 0, 0.80)"), "lineWidth" is the width of the drawn lines (default is 1). The plugin also adds four public methods: - setCrosshair( pos ) Set the position of the crosshair. Note that this is cleared if the user moves the mouse. "pos" is in coordinates of the plot and should be on the form { x: xpos, y: ypos } (you can use x2/x3/... if you're using multiple axes), which is coincidentally the same format as what you get from a "plothover" event. If "pos" is null, the crosshair is cleared. - clearCrosshair() Clear the crosshair. - lockCrosshair(pos) Cause the crosshair to lock to the current location, no longer updating if the user moves the mouse. Optionally supply a position (passed on to setCrosshair()) to move it to. Example usage: var myFlot = $.plot( $("#graph"), ..., { crosshair: { mode: "x" } } }; $("#graph").bind( "plothover", function ( evt, position, item ) { if ( item ) { // Lock the crosshair to the data point being hovered myFlot.lockCrosshair({ x: item.datapoint[ 0 ], y: item.datapoint[ 1 ] });

Copyright (c) 2007-2013 IOLA and Ole Laursen. Licensed under the MIT license. The plugin supports these options: selection: { mode: null or "x" or "y" or "xy", color: color, shape: "round" or "miter" or "bevel", minSize: number of pixels } Selection support is enabled by setting the mode to one of "x", "y" or "xy". In "x" mode, the user will only be able to specify the x range, similarly for "y" mode. 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. "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. The event handler gets a parameter with the ranges selected on the axes, like this: placeholder.bind( "plotselected", function( event, ranges ) { alert("You selected " + ranges.xaxis.from + " to " + ranges.xaxis.to) // similar for yaxis - with multiple axes, the extra ones are in // x2axis, x3axis, ... }); The "plotselected" event is only fired when the user has finished making the selection. A "plotselecting" event is fired during the process with the same parameters as the "plotselected" event, in case you want to know what's happening while it's happening, A "plotunselected" event with no arguments is emitted when the user clicks the mouse to remove the selection. As stated above, setting "minSize" to 0 will destroy this behavior. The plugin allso adds the following methods to the plot object: - setSelection( ranges, preventEvent ) Set the selection rectangle. The passed in ranges is on the same form as returned in the "plotselected" event. If the selection mode is "x", you should put in either an xaxis range, if the mode is "y" you need to put in an yaxis range and both xaxis and yaxis if the selection mode is "xy", like this: setSelection({ xaxis: { from: 0, to: 10 }, yaxis: { from: 40, to: 60 } }); setSelection will trigger the "plotselected" event when called. If you don't want that to happen, e.g. if you're inside a "plotselected" handler, pass true as the second parameter. If you are using multiple axes, you can specify the ranges on any of those, e.g. as x2axis/x3axis/... instead of xaxis, the plugin picks the first one it sees. - clearSelection( preventEvent ) Clear the selection rectangle. Pass in true to avoid getting a "plotunselected" event. - getSelection() Returns the current selection in the same format as the "plotselected" event.

Copyright (c) 2007-2014 IOLA and Ole Laursen. Licensed under the MIT license. The plugin assumes the data is sorted on x (or y if stacking horizontally). For line charts, it is assumed that if a line has an undefined gap (from a null point), then the line above it should have the same gap - insert zeros instead of "null" if you want another behaviour. This also holds for the start and end of the chart. Note that stacking a mix of positive and negative values in most instances doesn't make sense (so it looks weird). Two or more series are stacked when their "stack" attribute is set to the same key (which can be any number or string or just "true"). To specify the default stack, you can set the stack option like this: series: { stack: null/false, true, or a key (number/string) } You can also specify it for a single series, like this: $.plot( $("#placeholder"), [{ data: [ ... ], stack: true }]) The stacking order is determined by the order of the data series in the array (later series end up on top of the previous). Internally, the plugin modifies the datapoints in each series, adding an offset to the y value. For line series, extra data points are inserted through interpolation.
