The plugin defines plot.zoom({ center }), -plot.zoomOut() and plot.pan(offset) so you easily can add custom -controls. It also fires a "plotpan" and "plotzoom" event when -something happens, useful for synchronizing plots. - -Options: - - zoom: { - interactive: false - trigger: "dblclick" // or "click" for single click - amount: 1.5 // 2 = 200% (zoom in), 0.5 = 50% (zoom out) - } - - pan: { - interactive: false - cursor: "move" // CSS mouse cursor value used when dragging, e.g. "pointer" - frameRate: 20 - } - - xaxis, yaxis, x2axis, y2axis: { - zoomRange: null // or [number, number] (min range, max range) or false - panRange: null // or [number, number] (min, max) or false - } - -"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. - -"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). - -"zoomRange" is the interval in which zooming can happen, e.g. with -zoomRange: [1, 100] the zoom will never scale the axis so that the -difference between min and max is smaller than 1 or larger than 100. -You can set either end to null to ignore, e.g. [1, null]. If you set -zoomRange to false, zooming on that axis will be disabled. - -"panRange" confines the panning to stay within a range, e.g. with -panRange: [-10, 20] panning stops at -10 in one end and at 20 in the -other. Either can be null, e.g. [-10, null]. If you set -panRange to false, panning on that axis will be disabled. - -Example API usage: - - 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 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. - -*/ - - -// First two dependencies, jquery.event.drag.js and -// jquery.mousewheel.js, we put them inline here to save people the -// effort of downloading them. - -/* -jquery.event.drag.js ~ v1.5 ~ Copyright (c) 2008, Three Dub Media (http://threedubmedia.com) -Licensed under the MIT License ~ http://threedubmedia.googlecode.com/files/MIT-LICENSE.txt -*/ -(function(E){E.fn.drag=function(L,K,J){if(K){this.bind("dragstart",L)}if(J){this.bind("dragend",J)}return !L?this.trigger("drag"):this.bind("drag",K?K:L)};var A=E.event,B=A.special,F=B.drag={not:":input",distance:0,which:1,dragging:false,setup:function(J){J=E.extend({distance:F.distance,which:F.which,not:F.not},J||{});J.distance=I(J.distance);A.add(this,"mousedown",H,J);if(this.attachEvent){this.attachEvent("ondragstart",D)}},teardown:function(){A.remove(this,"mousedown",H);if(this===F.dragging){F.dragging=F.proxy=false}G(this,true);if(this.detachEvent){this.detachEvent("ondragstart",D)}}};B.dragstart=B.dragend={setup:function(){},teardown:function(){}};function H(L){var K=this,J,M=L.data||{};if(M.elem){K=L.dragTarget=M.elem;L.dragProxy=F.proxy||K;L.cursorOffsetX=M.pageX-M.left;L.cursorOffsetY=M.pageY-M.top;L.offsetX=L.pageX-L.cursorOffsetX;L.offsetY=L.pageY-L.cursorOffsetY}else{if(F.dragging||(M.which>0&&L.which!=M.which)||E(L.target).is(M.not)){return }}switch(L.type){case"mousedown":E.extend(M,E(K).offset(),{elem:K,target:L.target,pageX:L.pageX,pageY:L.pageY});A.add(document,"mousemove mouseup",H,M);G(K,false);F.dragging=null;return false;case !F.dragging&&"mousemove":if(I(L.pageX-M.pageX)+I(L.pageY-M.pageY)<M.distance){break}L.target=M.target;J=C(L,"dragstart",K);if(J!==false){F.dragging=K;F.proxy=L.dragProxy=E(J||K)[0]}case"mousemove":if(F.dragging){J=C(L,"drag",K);if(B.drop){B.drop.allowed=(J!==false);B.drop.handler(L)}if(J!==false){break}L.type="mouseup"}case"mouseup":A.remove(document,"mousemove mouseup",H);if(F.dragging){if(B.drop){B.drop.handler(L)}C(L,"dragend",K)}G(K,true);F.dragging=F.proxy=M.elem=false;break}return true}function C(M,K,L){M.type=K;var J=E.event.handle.call(L,M);return J===false?false:J||M.result}function I(J){return Math.pow(J,2)}function D(){return(F.dragging===false)}function G(K,J){if(!K){return }K.unselectable=J?"off":"on";K.onselectstart=function(){return J};if(K.style){K.style.MozUserSelect=J?"":"none"}}})(jQuery);
