I made a few graphs with the possibility of putting a mark inside, but I don't understand how to make the mark hoverable with the y-axis value.
$.plot($("#flot-chart-#ControlID"), series_#ControlID, {
series: {
lines: {
lineWidth: 2,
fill: #((Model.Series.Count() == 1).ToString().ToLower()),
},
bars: {
barWidth: 0.6,
align: "center"
},
points: {
fill: #((Model.Series.Count() == 1).ToString().ToLower()),
}
},
xaxis: {
ticks: xlabels_#ControlID,
tickDecimals: 0
},
colors: #Html.Raw(Newtonsoft.Json.JsonConvert.SerializeObject(Model.Series.Select(o => o.Color).ToArray())),
grid: {
color: "#999999",
hoverable: true,
clickable: true,
borderWidth: 0,
#if (Model.LimitLine != null)
{
<text>
markings: [
{ color: '#000', lineWidth: 1, yaxis: { from: #Model.LimitLine, to: #Model.LimitLine }},
]
</text>
}
},
legend: {
show: true
},
tooltip: true,
tooltipOpts: {
content: function(label, xval, yval) {
var content = getLabel_#(ControlID)(xval) + ": " + yval;
return content;
},
}
});
How can i show a tooltip with the value?
Graph example:
You can't do that with the tooltips plugin, but it is possible when doing the tooltips yourself. Something like this:
$("#placeholder").bind("plothover", function (event, pos, item) {
if (item) { // hovering over a datapoint
var x = item.datapoint[0].toFixed(2),
y = item.datapoint[1].toFixed(2);
$("#tooltip").html(item.series.label + " of " + x + " = " + y)
.css({top: item.pageY+5, left: item.pageX+5}).fadeIn(200);
} else {
var hideTooltip = true;
// you need to save the Flot object for this (here as "plot")
$.each(plot.getOptions().grid.markings, function(idx, marking) {
if (Math.abs(pos.y - marking.yaxis.to) < 10) {
$("#tooltip").html("Limit: " + marking.yaxis.to)
.css({top: pos.pageY + 5, left: pos.pageX + 5}).fadeIn(200);
hideTooltip = false;
return false;
}
});
if (hideTooltip) {
$("#tooltip").hide();
}
}
});
Based on this example.

I've seen tutorials and posts about getting data from the x axis into the tooltip but I am overriding it with categories and cannot figure out how to get the x axis to show up in the tooltip.
This is what im working with:
function showTooltip(x, y, contents) {
$('<div id="tooltip" class="flot-tooltip tooltip"><div class="tooltip-arrow"></div>' + contents + '</div>').css({
top: y - 43,
left: x - 15,
}).appendTo("body").fadeIn(200);
}
var data = [[1492854610, -1240],[1492939020, -1273],[1493025073, -1279],[1493117066, -1186],[1493198484, -1269],[1493289175, -1198],[1493370646, -1280],[1493458518, -1255],[1493543731, -1275],[1493630250, -1273],[1493716306, -1279],[1493803609, -1264],[1493889258, -1276],[1493975557, -1278],[1494064529, -1235],[1494155440, -1160],[1494237980, -1224],[1494321047, -1280],[1494407990, -1271],[1494494125, -1275],[1494581609, -1257],[1494668321, -1252],[1494753220, -1277],[1494847855, -1140],[1494925963, -1278],[1495012537, -1275],[1495099289, -1269],[1495188205, -1227],[1495273568, -1244],[1495358329, -1272]];
$.plot($("#placeholder"), [{

}
});
$("#placeholder").bind("plothover", function(event, pos, item) {
if (item) {
if (previousPoint != item.dataIndex) {
previousPoint = item.dataIndex;
$("#tooltip").remove();
var y = item.datapoint[1].toFixed();
showTooltip(item.pageX, item.pageY,
item.series.label + " = " + y);
}
} else {
$("#tooltip").remove();
previousPoint = null;
}
});
I am trying to get the times part of the categories. The item array has 3 pieces of data, none of which are the times
jFiddle:
http://jsfiddle.net/zw14y8c3/2/
The item.datapoint[0] data has the index of the x-axis tick. With that you can get the actual tick label from the ticks array:
var x = $("#placeholder").data('plot').getAxes().xaxis.ticks[item.datapoint[0]].label;
See the updated fiddle for the full example.
With the Highcharts value-in-legend plugin http://www.highcharts.com/plugin-registry/single/10/Value-In-Legend, I have been able to kind of implement a sort of multiple series total, but I do not understand how to get a total for a clicked y-axis point.
For example when I click, one day I will get the 3 separate series numbers, but I would like to get a total somehow as well, but I only know the y points on load and the visible y-points on redraw. I think the difficulty is getting the total of the 3 series points versus getting the individual point's value.

// As we're loading the data asynchronously, we don't know what order it will arrive. So
// we keep a counter and create the chart when all the data is loaded.

I am trying to show time intervals between Min and Max of a certain time range. Eg: 2015-04-30 10:20:00 and 2015-04-30 10:30:00 on x axis
I will be fetching all the values from database(which has datetime stored in 2015-04-30 10:27:58 format and passing it through webmethod.
If I create var data1 as
var data1 = [
['2015-04-30 10:27:58', 1690.25], ...
];
It won't work. So I am guessing I would need to convert '2015-04-30 10:27:58'milisecond ticks when creating var data1.
But I do not want to display time in a proper time format such as 10:27:58 instead of 1430369878000 on xaxis. (I want exclude date part).
How can I achieve this?
//RED
var data1 = [
[1430369878000, 1690.25], [1430369879000, 1696.3], [1430369880000, 1659.65]
];
//BLUE
var data2 = [
[1430369878000, 1682.1], [1430369879000, 1680.65], [1430369880000, 1685.1]
];

The options for the x-axis are under the name xaxes not xaxis therefore they are not used. (Also your min and max values are outside of the data range.)
// not xaxes:
xaxis: {
mode: "time",
//min: parseInt((new Date("2015-04-30 10:27:58")).getTime()),
//max: parseInt((new Date("2015-04-30 10:43:39")).getTime()),
timeformat: "%H/%M/%S"
},
See this fiddle for a working example.
PS: You use the $.plot() function with setInterval which is okay but you should only call UseTooltip() once.
I'm using Highcharts to show the % difference between the columns.
The labels above the columns represent that bars total. The % between the columns show a % change between each bar. I have positioned the x-axis OK, but the y-axis values are difficult. My aim is to:
Align % values to 50% on the y-Axis (half the height of the chart) and in between the columns so it shows a straight line of values. Currently these numbers are relative to the height of the bar column values.

I have following example: http://jsfiddle.net/ondra15/7mb8K/1/.
I want to have together two example (multiple axes and zooming). Example zooming do not work correct - if I indicate some data in chart for zooming - do not work. Nothing happens.
Original Zooming (correct) solution works here http://www.flotcharts.org/flot/examples/zooming/index.html
Can any some idea for my code? Thanks
