I have this table-
html.Div([
dash_table.DataTable(
id = 'datatable-interactivity',
data = df.to_dict('records'),
editable = False,
style_filter = {
'backgroundColor': '#252e3f',
'color': 'white'
},
style_header = {
'backgroundColor': '#252e3f',
'color': 'white'
},
style_data = {
'backgroundColor': '#252e3f',
'color': 'white'
},
style_cell = {
'overflow': 'hidden',
'textOverflow': 'ellipsis',
'maxWidth': 0
}
)])
], style = {'background-color': '#1f2630'})
The filter text shows up as a dark gray even though I set the color to white. This includes both the text that I add into the filter cells and the default placeholders.
Is there a different argument I should include to change the color?

I am trying to add basic interactivity to my AMCHARTS 5 labels. Take this chart as an example:
I need to be able to click on the names at the left of the chart. That is actually yAxis because I use an inverted chart.
In the function that creates the series, I placed this code:
series.columns.template.events.once("click", function(ev) {
console.log("Clicked on a column", ev.target);
});
And it makes my bars to be clickable. I don't know how to refer to the labels on the left.
Labels as interactive elements in amCharts 5 are tricky. Basically, it's super hard to determine hover/click over just text because it's impossible to completely eradicate antialising, and the actual colored area is super tiny.
Therefore, if we need tooltip to be interactive - have a hover tooltip or handle click events - we need to add a background to it.
The background does not necessarily have to be visible: we can just set its fillOpacity: 0 to make it completely transparent.
Source: Labels – amCharts 5 Documentation
After the declaration and initialization of your yAxis, you can put this piece of code:
yAxis.get("renderer").labels.template.setup = target => {
target.setAll({
cursorOverStyle: "pointer",
background: am5.Rectangle.new(root, {
fill: am5.color(0x000000),
fillOpacity: 0
})
});
};
yAxis.get("renderer").labels.template.events.on("click", e => {
console.log(e.target.dataItem.dataContext.category);
});
Full example:
am5.ready(() => {
let root = am5.Root.new("chartdiv");
let chart = root.container.children.push(am5xy.XYChart.new(root, {}));
let data = [{
category: "Category 1",
value: 10
}, {
category: "Category 2",
value: 20
}, {
category: "Category 3",
value: 15
}];
let yAxis = chart.yAxes.push(am5xy.CategoryAxis.new(root, {
categoryField: "category",
renderer: am5xy.AxisRendererY.new(root, {
inversed: true,
cellStartLocation: 0.1,
cellEndLocation: 0.9
})
}));
yAxis.data.setAll(data);
yAxis.get("renderer").labels.template.setup = target => {
target.setAll({
cursorOverStyle: "pointer",
background: am5.Rectangle.new(root, {
fill: am5.color(0x000000),
fillOpacity: 0
})
});
};
yAxis.get("renderer").labels.template.events.on("click", e => {
console.log(e.target.dataItem.dataContext.category);
});
let xAxis = chart.xAxes.push(am5xy.ValueAxis.new(root, {
min: 0,
renderer: am5xy.AxisRendererX.new(root, {})
}));
let series = chart.series.push(am5xy.ColumnSeries.new(root, {
name: "Series",
xAxis: xAxis,
yAxis: yAxis,
valueXField: "value",
categoryYField: "category"
}));
series.data.setAll(data);
});

I am using chart.js, Laravel 5.4 and blade templates.
I have to show doughnut chart and when user click on particular area then it should show the name of selected label and value belongs to it in the modal but firstly I am not able to get label name when user click on doughnut chart.
<br>var bookings = {!! json_encode($bookings) !!} ;
<br>var map={"confirmed":{"label":"Confirmed","color":"#4BC0C0"},"cancelled":{"label":"Cancelled","color":"#FFCD56"},"on_request":{"label":"On Request","color":"#FF6384"}}
<br>#if($hasChart)
<br>var labels=[],colors=[],numbers=[],hasChart=false;
<br>for (var property in map) {
<br>if(bookings[property].length>=0){
<br>hasChart=true;
<br>labels.push(map[property]["label"]);
<br>colors.push(map[property]["color"]);
<br>numbers.push(bookings[property].length);
}
}
var ctx = document.getElementById('doughnut-chart').getContext('2d');
<br>var chart = new Chart(ctx, {
<br>type: 'doughnut',
<br>data: {
<br>labels: labels,
<br>datasets: [
<br>{
backgroundColor: colors,
data: numbers
}
]
<br>},
<br>options: {
onClick: (e) => {
<br>//to do get value of selected label
<br>$('#bookingInfoModal').modal('show');
},

padding: 50,
labels: {
boxWidth: 10,

},
<br>},
<br>},
<br>},
<br>});
I got it. it's working now.
options: {
onClick: (e,legend) => {
console.log(legend[0].index);
alert(chart.data.labels[legend[0].index]);
},
}
i want my chart start at 12:00am and only draw the points when data avaiable. In most of my case data starts at 06:00am. now i want the chart look likes this.
i had generate the label from the created_at provide by the query. so, the label are equavalent to all the created_at present. My chart looks like this.
i want my label to start at 12:00Am but graph from the first created_at point. or null value can be replaced as 0.

I have a scatter plot as shown below with code. How do I make the title area not take up this much space? Just to be clear, I don't mean the font size of the title, but the empty space the title area occupies.
var rstTrace = {
x: x_data,
y: y_data,
mode: 'markers',
type: 'scatter',
marker: {
size: 3,
color: chartMarkerColor
}
};
var rstLayout = {
height: 400,
title: {
text: 'My Title',
font: {
family: 'Tahoma',
size: 15
}
},
xaxis: {
showline: true,
zeroline: false,
linecolor: '#D3D3D3', // light gray
tickcolor: '#D3D3D3'
},
yaxis: {
showline: true,
zeroline: false,
linecolor: '#D3D3D3',
tickcolor: '#D3D3D3'
},
backgroundcolor: '#D3D3D3'
};
Plotly.newPlot('resultDiv', [rstTrace], rstLayout);
You can change the graph's top margin
https://plot.ly/javascript/setting-graph-size/#adjusting-height-width-and-margins
Example
var rstLayout = {
margin:{
t: 10
}
};
The top margin however accounts for all the space above the chart, so if you wish to move the title up or down so that it isn't centered, you could also use this workaround:
document.querySelector('.gtitle').setAttribute('y', 100)
The position of the text element is controlled by the attributes x and y. You can change y to whatever value you see fit to move the title down. Note that you'd need to make sure this runs after the svg is loaded in the page.
Help me, please.
How to change the labels to the image (icon) in bar chart.js ?
I mean, change from this
change labels: "LifeWall_files/logo.png","Bodily Functions","Sleep"
to this
bottom icons
The easiest way to do this would be to get a font that includes these icons and then set the font family for the ticks
...
options: {
scales: {
xAxes: [{
ticks: {
fontFamily: 'FontAwesome'
}
}]
}
}
};
and then specify the appropriate character codes in your labels
labels: ["\uf24e", "\uf1b9", "\uf242", "\uf0fc", "\uf236"],
With the FontAwesome CSS, the above would give you
The Plugin Core API offers a range of hooks that may be used for performing custom code. You can use the afterDraw hook to draw images (icons) instead of tick labels directly on the canvas using CanvasRenderingContext2D.
You'll also have to instruct Chart.js not to display the default tick labels. This can be done through the following definition inside the chart options.
scales: {
xAxes: [{
ticks: {
display: false
}
}],
Further you need to define some padding at the bottom of the chart, otherwise you'll see only part of the images.
layout: {
padding: {
bottom: 30
}
},
Please have a look at the runnable code snippet below.
const labels = ['red vans', 'blue vans', 'green vans', 'gray vans'];
const images = ['https://i.stack.imgur.com/2RAv2.png', 'https://i.stack.imgur.com/Tq5DA.png', 'https://i.stack.imgur.com/3KRtW.png', 'https://i.stack.imgur.com/iLyVi.png'];
const values = [48, 56, 33, 44];
new Chart(document.getElementById("myChart"), {
type: "bar",
plugins: [{
afterDraw: chart => {
var ctx = chart.chart.ctx;
var xAxis = chart.scales['x-axis-0'];
var yAxis = chart.scales['y-axis-0'];
xAxis.ticks.forEach((value, index) => {
var x = xAxis.getPixelForTick(index);
var image = new Image();
image.src = images[index],
ctx.drawImage(image, x - 12, yAxis.bottom + 10);
});
}
}],
data: {
labels: labels,
datasets: [{
label: 'My Dataset',
data: values,
backgroundColor: ['red', 'blue', 'green', 'lightgray']
}]
},
options: {
responsive: true,
layout: {
padding: {
bottom: 30
}
},
legend: {

},
