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" } } }; - $("#graph").bind( "plothover", function ( evt, position, item ) { - if ( item ) { - // Lock the crosshair to the data point being hovered - myFlot.lockCrosshair({ - x: item.datapoint[ 0 ], - y: item.datapoint[ 1 ] - }); - } else { - // Return normal crosshair operation - myFlot.unlockCrosshair(); - } - }); - - - unlockCrosshair() - - Free the crosshair to move again after locking it. -*/ - -(function ($) { - var options = { - crosshair: { - mode: null, // one of null, "x", "y" or "xy", - color: "rgba(170, 0, 0, 0.80)", - lineWidth: 1 - } - }; - - function init(plot) { - // position of crosshair in pixels - var crosshair = { x: -1, y: -1, locked: false }; - - plot.setCrosshair = function setCrosshair(pos) { - if (!pos) - crosshair.x = -1; - else { - var o = plot.p2c(pos); - crosshair.x = Math.max(0, Math.min(o.left, plot.width())); - crosshair.y = Math.max(0, Math.min(o.top, plot.height())); - } - - plot.triggerRedrawOverlay(); - }; - - plot.clearCrosshair = plot.setCrosshair; // passes null for pos - - plot.lockCrosshair = function lockCrosshair(pos) { - if (pos) - plot.setCrosshair(pos); - crosshair.locked = true; - }; - - plot.unlockCrosshair = function unlockCrosshair() { - crosshair.locked = false; - }; - - function onMouseOut(e) { - if (crosshair.locked) - return; - - if (crosshair.x != -1) { - crosshair.x = -1; - plot.triggerRedrawOverlay(); - } - } - - function onMouseMove(e) { - if (crosshair.locked) - return; - - if (plot.getSelection && plot.getSelection()) { - crosshair.x = -1; // hide the crosshair while selecting - return; - } - - var offset = plot.offset(); - crosshair.x = Math.max(0, Math.min(e.pageX - offset.left, plot.width())); - crosshair.y = Math.max(0, Math.min(e.pageY - offset.top, plot.height())); - plot.triggerRedrawOverlay(); - } - - plot.hooks.bindEvents.push(function (plot, eventHolder) { - if (!plot.getOptions().crosshair.mode) - return; - - eventHolder.mouseout(onMouseOut); - eventHolder.mousemove(onMouseMove); - }); - - plot.hooks.drawOverlay.push(function (plot, ctx) { - var c = plot.getOptions().crosshair; - if (!c.mode) - return; - - var plotOffset = plot.getPlotOffset(); - - ctx.save(); - ctx.translate(plotOffset.left, plotOffset.top); - - if (crosshair.x != -1) { - var adj = plot.getOptions().crosshair.lineWidth % 2 === 0 ? 0 : 0.5; - - ctx.strokeStyle = c.color; - ctx.lineWidth = c.lineWidth; - ctx.lineJoin = "round"; - - ctx.beginPath(); - if (c.mode.indexOf("x") != -1) { - var drawX = Math.round(crosshair.x) + adj; - ctx.moveTo(drawX, 0); - ctx.lineTo(drawX, plot.height()); - } - if (c.mode.indexOf("y") != -1) { - var drawY = Math.round(crosshair.y) + adj; - ctx.moveTo(0, drawY); - ctx.lineTo(plot.width(), drawY); - } - ctx.stroke(); - } - ctx.restore(); - }); - - plot.hooks.shutdown.push(function (plot, eventHolder) { - eventHolder.unbind("mouseout", onMouseOut); - eventHolder.unbind("mousemove", onMouseMove); - }); - } - - $.plot.plugins.push({ - init: init, - options: options, - name: 'crosshair', - version: '1.0' - }); -})(jQuery); |
