plotly manually set a onesided range - javascript

In plotly the axis range can be set manually with yaxis: {range: [0,10]}
e.g. https://codepen.io/plotly/pen/YXbwyo.
However, how can I set only the lower limit manually to 0, while the upper limit should autoscale?

You can set the parameters rangemode:'tozero' and autorange:true in the layout.
I modified the traces in your codepen to not include the points where x=0 and the lower limit of the range is indeed 0 while the upper limit autoscales to the largest x- and y-values.
var trace1 = {
x: [1, 2, 3, 4, 5, 6, 7, 8],
y: [7, 6, 5, 4, 3, 2, 1, 0],
type: 'scatter'
};
var trace2 = {
x: [1, 2, 3, 4, 5, 6, 7, 8],
y: [1, 2, 3, 4, 5, 6, 7, 8],
type: 'scatter'
};
var data = [trace1, trace2];
var layout = {
xaxis: {rangemode: 'tozero',
autorange: true},
yaxis: {rangemode: 'tozero',
autorange: true},
};
Plotly.newPlot('myDiv', data, layout, {showSendToCloud: true});

Boxplot in highcharts displaying incorrect values for high, and median

I am creating a box plot from a simple series of data:
var box_plot = Highcharts.chart(container, {
chart: {
type: 'boxplot'
},
title: {
text: chart_title
},
legend: {
enabled: false
},
series: [{
name: 'Observations',
data: [
[1,2,3,4,5,6,7,8,9,10,11,12,13]
],
tooltip: {
headerFormat: '<em>Experiment No {point.key}</em><br/>'
}
}]
});
return box_plot;
But when the box plot is generated, the high is shown as 6 and median as 4. In the data the high is 13 and median is 6.
Please inform what I am doing wrong. Screenshot of code and box plot attached.
Thank You
You can provide data to boxplot series in two ways:
An array of arrays with 6 or 5 values. In this case, the values correspond to x,low,q1,median,q3,high. If the first value is a string, it is applied as the name of the point, and the x value is inferred. The x value can also be omitted, in which case the inner arrays should be of length 5. Then the x value is automatically calculated, either starting at 0 and incremented by 1, or from pointStart and pointInterval given in the series options.
data: [
[0, 3, 0, 10, 3, 5],
[1, 7, 8, 7, 2, 9],
[2, 6, 9, 5, 1, 3]
]
An array of objects with named values. The following snippet shows only a few settings, see the complete options set below. If the total number of data points exceeds the series' turboThreshold, this option is not available.
data: [{
x: 1,
low: 4,
q1: 9,
median: 9,
q3: 1,
high: 10,
name: "Point2",
color: "#00FF00"
}, {
x: 1,
low: 5,
q1: 7,
median: 3,
q3: 6,
high: 2,
name: "Point1",
color: "#FF00FF"
}]
Highcharts doesn't have any auto data calculation procedure in this case. You need to prepare the required data structure by yourself. For example:
const data = [
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]
];
const processedData = data.map((dataEl, index) => ({
x: index,
low: Math.min(...dataEl),
median: dataEl[(dataEl.length - 1) / 2],
high: Math.max(...dataEl),
...
}));

Multiple X shared axis in plot.ly subplots

I have two subplots with shared x axis and I want to be able to zoom them both - when I zoom one the second adjust automatically but I have problem: x axis can be presented only on first axis or only on second axis.
How can I display x axis below both plots?
Cheers, Fih
var trace1 = {
x: [1, 2, 3],
y: [2, 3, 4],
type: 'scatter'
};
var trace3 = {
x: [2, 3, 4],
y: [600, 700, 800],
xaxis: 'x',
yaxis: 'y3',
type: 'scatter'
};
var data = [trace1, trace3];
var layout = {
xaxis: {
domain: [0, 1],
anchor: ('y', 'y3'),
},
yaxis: {
domain: [0, 0.45],
},
yaxis3: {
domain: [0.55, 1]},
anchor: 'x',
};
Plotly.newPlot('compGraph', data, layout);
You can add "subplots" into layout:
var layout = {
grid: {
rows: 2,
columns: 1,
subplots:[['xy'], ['xy3']],
roworder:'bottom to top'},
};

Toggle visibility of (plotly.js - scatter) y-axis & traces

New to plotly.js
(I am in angular environment)
I wanna put the traces inside of a multi-select drop menu. Same for all the y axis. To be able to toggle the visibility of these. Suggestions...the easy/right way.
I tried to affect the svg containers with css but no effect:
For axis:
var update = {
'yaxis.visible': false
};
Plotly.relayout(myDiv, update)
For traces:
data = [
{
line: {width: 5},
name: "myName1",
type: "scatter",
visible: "legendonly", // Plot trace but hide it to the user
x: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
y: [10, 11, 2, 23, 14, 5, 16, 7, 18, 29, 10]
},
{
line: {width: 5},
name: "myName2",
type: "scatter",
visible: "legendonly" ,// Plot trace but hide it to the user
x: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
y: [10, 1, 12, 13, 4, 25, 16, 17, 8, 19, 20]
}
];
allTraces=document.getElementById("myDiv").data; // Get data from chart AFTER plotting it.
// Find index of trace-object with "name" property = "text to find":
result = allTraces.findIndex(obj => {
return obj.name === "text to find";
}
// Make specified trace visible to user:
Plotly.restyle(document.getElementById("myDiv"), {"visible": true}, [result]);

How to insert values in bars (flotcharts)

I have some problems to show some values in bars. I want a chart like this: Example. I don't know what I'm missing in here.
$('#myModalChart').on('shown.bs.modal', function (e) {
var data = [{
label: "Foo",
data: [
[2],
[3, 9, 12],
[6, 0, 3],
[9, 11, 12],
[12, 0, 1],
[15, 0, 2],
[18],
[3, 12, 12],
[9, 12, 12]
]
},
{
label: "Bar",
data: [
[2],
[3, 0, 5],
[6, 3, 7],
[9, 4, 11],
[12, 1, 3],
[15, 2, 5],
[18]
]
},
{
label: "Tree",
data: [
[2],
[3, 5, 9],
[6, 7, 15],
[9, 0, 4],
[12, 3, 13],
[15, 5, 17],
[15, 17, 17],
[12, 13, 13],
[6, 15, 15],
[18]
]
},];
var options = {
series: {
bars: {
show: true,
barWidth: 1
}
},
xaxis: {
align: "center",
ticks: [
[3.5, 'text1'],
[6.5, 'text2'],
[9.5, 'text3'],
[12.5, 'text4'],
[15.5, 'text5']
]
}
};
var plot = $.plot("#chart2", data, options)
});
I want a chart like this, with labels in it. And I wish have in all of them.
What I'm missing?
You have to create and place the data value labels yourself. How to do this can be seen in this answer.
I created a fiddle adjusting it to your code. Only the first data series (foo) has labels for now. you will have to adjust the position. The relevant code:
$.each(plot.getData()[0].data, function (i, el) {
if (el.length > 1) {
var o = plot.pointOffset({
x: el[0],
y: el[1]
});
$('<div class="data-point-label">' + el[1] + '</div>').css({
position: 'absolute',
left: o.left + 4,
top: o.top,
'text-align': 'center',
display: 'none'
}).appendTo(plot.getPlaceholder()).fadeIn('slow');
}
});
But you may also have to cleanup your data. You have multiple data points with the same x values (which means bars behind / in front of each other which leads to some being invisible). Take a look at the side-by-side and stack plugins on the flot plugin page.

Jquery Flot fill two dataset with DateTime and make a overlap effect

I have a chart (image bellow), where the green line has a reference to the year 2014, and the purple line will be 2013.
var data1 = [
[gd(2014, 1, 1), 4], [gd(2014, 2, 1), 8], [gd(2014, 3, 1), 4], [gd(2014, 4, 1), 10],
[gd(2014, 5, 1), 4], [gd(2014, 6, 1), 16], [gd(2014, 7, 1), 5]];
var data2 = [
[gd(2014, 1, 1), 1], [gd(2014, 2, 1), 0], [gd(2014, 3, 1), 2], [gd(2014, 4, 1), 0],
[gd(2014, 5, 1), 1], [gd(2014, 6, 1), 3], [gd(2014, 7, 1), 1], [gd(2014, 8, 1), 5],
[gd(2014, 9, 1), 2], [gd(2014, 10, 1), 3], [gd(2014, 11, 1), 2], [gd(2014, 12, 1), 1]];
This is the dataset, but look that I put both dataset in 2014 year because if I put 2014 in one dataset and 2013 in another, I miss the overlap effect and I need that effect for comparsion.
This is what happens if a put the 2013 year in one dataset and 2014 in another (image below)
How can I do the same chart, but with this overlap effect, using the 2013 year in one dataset?
This also will fix my hover functionallity.
Code
var data1 = [
[gd(2014, 1, 1), 4], [gd(2014, 2, 1), 8], [gd(2014, 3, 1), 4], [gd(2014, 4, 1), 10],
[gd(2014, 5, 1), 4], [gd(2014, 6, 1), 16], [gd(2014, 7, 1), 5]];
var data2 = [
[gd(2014, 1, 1), 1], [gd(2014, 2, 1), 0], [gd(2014, 3, 1), 2], [gd(2014, 4, 1), 0],
[gd(2014, 5, 1), 1], [gd(2014, 6, 1), 3], [gd(2014, 7, 1), 1], [gd(2014, 8, 1), 5],
[gd(2014, 9, 1), 2], [gd(2014, 10, 1), 3], [gd(2014, 11, 1), 2], [gd(2014, 12, 1), 1]];

data1, data2

timeformat: "%b/%y"
},
yaxis: {
ticks: 4
}
}
);
function gd(year, month, day) {
return new Date(year, month - 1, day).getTime();
}
You use the concept of multiple axes, but just hide the second axis.
To do this you create two data sets, each with their own axis:
var data2014 = {
label: "2014",
data: data1,
xaxis: 1
};
var data2013 = {
label: "2013",
data: data2,
xaxis: 2
};
and then in the axes option setting, set ticks to false to hide one axis.
The max setting for the 2014 data is important, otherwise the data set will scale to fill the whole graph:
xaxes: [{
mode: "time",
tickSize: [1, "month"],
tickLength: null,
color: "#838383",
timeformat: "%b",
max: (new Date("2014/12/1")).getTime()
},{
ticks: false
}],
