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"), [{

{ color: '#000', lineWidth: 1, yaxis: { from: 0, to: 0 } },
]
},
legend: {

}
});
$("#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.

For some reason no matter what we try the labels on our area chart series seem to have a mind of their own. Even though a short label looks like it could fit inside the area of the data, it puts it right on the end line, bleeding out of the area.
We suspect it might be due to having min and max dates that are beyond the series min and max, but these buffer zones are a requirement.
Is there an option to make labels be contained to their own series and not bleed off into whitespace?
Below is the example chart configuration and here is the JSFiddle: http://jsfiddle.net/sLqu34cn/
Highcharts.chart('container', {
chart: {
type: "area",
height: 200
},
legend: {
enabled: false
},

pointPlacement: "on"
},
series: {
lineWidth: 0,
fillOpacity: 1,
marker: {

},
label: {
style: {
color: "white",
textOutline: "1px black"
}
}
}
},
series: [
{

data: [[1532217600000, 1], [1532822400000, 0]],

},
{

data: [[1532217600000, 0], [1532822400000, 2]],

}
],
xAxis: {
tickWidth: 1,
title: {

},
labels: {
format: "{value: %b %e}"
},
max: 1533243166375,
min: 1530478366375,
type: "datetime"
},
yAxis: {
tickInterval: 20,
title: {
text: null
},
labels: {
format: "{value}%"
},
max: 100,
min: 0
},
tooltip: {}
});
Probably not the perfect solution, but you can create some customization to position the series labels. This is an example how to manually calculate the center of area in triangle shape:
Highcharts.wrap(Highcharts.Chart.prototype, 'drawSeriesLabels', function(proceed) {
proceed.apply(this, Array.prototype.slice.call(arguments, 1));
var chart = this,
plotTop = chart.plotTop,
plotLeft = chart.plotLeft,
series = chart.series,
height = chart.yAxis[0].height,
x1,
x2,
y1,
y2;
x1 = ((series[0].graphPath[1] + plotLeft) * 2 + series[0].graphPath[4] + plotLeft) / 3;
y1 = (height + plotTop + series[0].graphPath[2] + plotTop + series[0].graphPath[5] + plotTop) / 3;
x2 = (series[1].graphPath[1] + plotLeft + (series[1].graphPath[4] + plotLeft) * 2) / 3;
y2 = ((series[1].graphPath[2] + plotTop) * 2 + series[1].graphPath[5] + plotTop) / 3;
series[0].labelBySeries.attr({
x: x1,
y: y1,
align: 'center'
});
series[1].labelBySeries.attr({
x: x2,
y: y2,
align: 'center'
});
});

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 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]
];
var dataset = [
{
label: "Sell out",
data: data1,
color: "#FF0000",
points: { fillColor: "#FF0000", show: true },
lines: { show: true }
},
{
label: "Buy in",
data: data2,
color: "#0062E3",
points: { fillColor: "#0062E3", show: true },
lines: { show: true }
}

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 have two bar charts, one of them shows top ten categories, the other one shows min ten categories.
There is no problem with top ten bar chart, but I use the very same code to draw min ten bar chart that I used in top ten bar chart, but here is the result.
This is top ten:
And this is min ten:
As you can see above image, min ten chart's bars look like damaged and labels below the bars can't be seen.
And here is the codes that produce these results:

Maybe the positioning is off because of when the chart is being rendered? Try drawing the charts only once their corresponding tab is selected and visible.
I want to process data from a .csv file to:

I'm not sure what you are asking, but I'll take a shot at it...
First things first, this snippet of code is not sound. It'll not only skip NaNs but 0s as well (which is valid numeric data):
else if(parseFloat(csvData[rowIndex][colIndex]))
{
seriesItem.data.push(parseFloat(csvData[rowIndex][colIndex]));
}
Instead I'd do:
//first column data as categories,
if (colIndex == 0)
{
categories.push(csvData[rowIndex][0]);
}
else
{
var fVal = parseFloat(csvData[rowIndex][colIndex]);
if (!isNaN(fVal))
{
fVal = fVal / 10.0; //<-- here's the division!!
seriesItem.data.push(fVal);
}
}
As far as how to exclude outliers, the big question there is how do you want to exclude outliers? A simple min/max criteria? Then just check that fVal is within those limits before seriesItem.data.push...
