[Merge] lp:~lucio.torre/graphite/add-flot into lp:graphite
Lucio Torre has proposed merging lp:~lucio.torre/graphite/add-flot into lp:graphite.
Requested reviews:
graphite-dev (graphite-dev)
Adds a new interface for rendering graphs with the following features:
- rendering is done client side
- you can mouse-over data points to see their value and to which series they belong
- you can zoom into portions of the data
- you have an overview of the plot
- you can move the series between any of the two axis
- autocomplete for metric input
- faster manipulation of graph series
We are currently working with this live to see how well it copes with lots of data. So far it seems to work ok. I find it very useful to have two axis and an easy way to tell which series is the one that i am pointing with the mouse (with many series colors become very similar)
Please let me know what you think.

+/*
+Flot plugin for showing a crosshair, thin lines, when the mouse hovers
+over the plot.
+
+ 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" should be on the form { x: xpos,
+ y: ypos } (or x2 and y2 if you're using the secondary 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.

+Flot plugin for selecting regions.
+
+The plugin defines the following options:
+
+ selection: {
+ mode: null or "x" or "y" or "xy",
+ color: color
+ }
+
+You enable selection support 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.
+
+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 one extra 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, secondary axes are in x2axis
+ // and y2axis if present
+ });
+
+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.
+
+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 (or x2axis) object,
+ if the mode is "y" you need to put in an yaxis (or y2axis) object
+ and both xaxis/x2axis and yaxis/y2axis 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.
+
+- 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. If there's currently no selection, the
+ function returns null.
