I have custom icon for zoom.
import zoomIcon from "common/assets/icons/zoom.svg";
feature: {
dataZoom: {
yAxisIndex: "none",
icon: {
zoom: `${urlImgBase}${zoomIcon}`,
back: `${urlImgBase}${resetIcon}`,
},
iconStyle: {
color: "#91cc75", // doesn't work
},
},
},
Inside svg I did -> stroke="currentColor". And it doesn't work. I have all time default black color.
How to change color my svg icon when I chosed "zoom"?

I use this kind of chart - https://echarts.apache.org/examples/en/editor.html?c=dataset-link
If I add to the first item for series color red (line:22), so the code looks like:
{
type: 'line',
color: 'red',
smooth: true,
seriesLayoutBy: 'row',
emphasis: { focus: 'series' }
},
It changes the color only in the chart but not in the pie, thank you for solution
Change the global color palette instead of changing colors for each series.
Here is an example based on the one you gave.
option = {
...
//Set the global color palette
color: ['#c23531','#2f4554','#61a0a8','#d48265','#91c7ae',
'#749f83','#ca8622','#bda29a','#6e7074','#546570','#c4ccd3'],
series : [
...
]
}
So what Im trying to do is to change the color of the values inside the bars of a Bar chart. I have tried all options and also have a pen where it doesnt seem to work: https://codepen.io/vbbalaji/pen/oNbwbpm

There are two problems here:
You need to include the chartjs datalabels script in order to use it. Make sure you include this script after the main Chart.js library: https://cdn.jsdelivr.net/npm/chartjs-plugin-datalabels#0.7.0.
Your datalabels options should be nested within the key plugins.
Here's the corrected config:
{
type: "horizontalBar",
data: {
labels: ["Red", "Amber", "Green"],
datasets: [
{
backgroundColor: ["#db5935", "#f0ae43", "#3cba9f"],
data: [2, -4, 6]
}
]
},
options: {
legend: { display: false },
title: { display: true, text: "Health Variance" },
plugins: {
datalabels: {
color: "blue",
labels: {
title: { color: "blue", font: { weight: "bold" } },
value: { color: "green" }
}
}
}
}
}
It looks like this:
Here's your updated codepen: https://codepen.io/typpo/pen/oNbwxvK
Draw a basic line chart using Chart.js version 2.8.0.
Observe the rightmost data point is cut off. But the leftmost data point (the first data point) looks intact.
I’ve changed the size of the data point circles by changing values of pointRadius. But even in the smallest value, the data point still gets cut off.
I’m not using any plugin or fancy settings. I am filling the chart are with light gray background colour. But other than that, everything else is a box standard Chart.js.
I’ve recreated the issue here:
https://codepen.io/LeoU/pen/gVLybO
And here is my options settings.
options: {
legend: {
display: false,
},
tooltips: {
callbacks: {
label: function (tooltipItem, data) {
var tooltipValue = data.datasets[tooltipItem.datasetIndex].data[tooltipItem.index];
return "£" + parseInt(tooltipValue).toLocaleString();
}
}
},
scales: {
yAxes: [{
gridLines: {
color: "white",
lineWidth: 2
},
ticks: {
beginAtZero: true,
min: 0,
stepSize: 500000,
callback: function(value, index, values) {
return "£" + value.toLocaleString();
},
},
scaleLabel: {
display: true,
labelString: "Median house price"
}
}],
xAxes: [{
display: false,
ticks: {
display: false
}
}]
}
},
Has anyone seen a similar problem with Chart.js?
You can use offset
scales: {
xAxes: [{
offset: true
}]
}
I fixed this by adding padding value to the right hand side of the chart.
I played around with the exact number and 4 looked about right for my chart. But I’d imagine the right number will depend on the size of your pointRadius and other variables you have.
This is what it looks like for me with the changes.
options: {
layout: {
padding: {
left: 0,
right: 4,
top: 0,
bottom: 0
}
}
}
For more about padding for Chart.js, this is their instruction page.
https://www.chartjs.org/docs/latest/configuration/layout.html
It is annoying. And, this should be a default setting, really. But this fixed the problem for me.
I'm trying to specifically target the first and last x-axis labels, which are text elements, and alter their attributes.
To preface this issue, I was trying to keep the first and last x-axis labels within the confines of the Highcharts container. Unfortunately, they are cutting off in the UI.
This is my configuration:
xAxis: [{
type: 'datetime',
showFirstLabel: true,
showLastLabel: true,
labels: {
step: 3,
formatter: function(){
return options.labels[this.value];
},
style: {
fontSize: '10px',
color: '#9c9c9c'
},
// x: 5,
y: 10
},
startOnTick: true,
// lineColor: 'transparent',
tickLength: 0,
minPadding: 0,
maxPadding: 0
}],
The step key is causing this I realize. Otherwise, I would be able to use overflow:justify, but I wanted the step. So, I then decided that perhaps altering the SVG would be a good solution. It worked when the chart is first loaded, but it does not work when being redrawn.
This was my solution on 'load', which I'd like to replicate on 'redraw':
Highcharts.Chart.prototype.callbacks.push(function(chart){
$('.highcharts-axis-labels.highcharts-xaxis-labels text').first().attr('x', 25);
$('.highcharts-axis-labels.highcharts-xaxis-labels text').last().attr('x', 813);
});
You should configure these callbacks in the options of your chart. It's cleaner that way:
function moveLabels(){
$('.highcharts-axis-labels.highcharts-xaxis-labels text').first().attr('x', 25);
$('.highcharts-axis-labels.highcharts-xaxis-labels text').last().attr('x', 813);
}
$('#container').highcharts({
chart: {
events: {
load: moveLabels
redraw: moveLabels
}
}
},
...
I have a basic bar chart I'm presenting in flot (5 bars, displaying the % per status).
$.plot($("#placeholder"), [
{
label: 'Failed',
data: [[0,10]],
bars: { show: true }
},
{
label: 'Passed',
data: [[1,15]],
bars: { show: true }
},
{
label: 'Not Run',
data: [[2,30]],
bars: { show: true }
},
{
label: 'Blocked',
data: [[3,5]],
bars: { show: true }
},
{
label: 'In Progress',
data: [[4,40]],
bars: { show: true }
}
],
{
xaxis: {
ticks: [[0.5, "Failed"], [1.5, "Passed"], [2.5, "Not Run"], [3.5, "Blocked"], [4.5, "In Progress"]]
},
legend: {
show: false
}
});
I'm finding the font used for the tick values on the x axis are a little too big, especially when the graph is displayed at small dimensions ie. 240x100. I've read the API documentation, but can't find how to control the tick label sizes.
Is this possible OOTB?
It doesn't appear you can set the font size via the API, but you can use css to set the size of the tick labels.
.tickLabel { font-size: 80% }
Here's an example directly from the API:
xaxis:{
font:{
size:11,
style:"italic",
weight:"bold",
family:"sans-serif",
variant:"small-caps"
}
}
http://flot.googlecode.com/svn/trunk/API.txt
The above two answers won't work on the latest version of flot, as they no longer use 'real' text (the text is drawn instead). Instead specify these options:
{xaxis: {font: size: some_number}, yaxis: {font: size: some_number}}
(replace some_number with the desired size in points)
I used the following:
CSS File/SCSS File
#graph_label .tickLabel{
font-size: 50%;
}
Index.html or place where you are plotting the graph area
$.plot($("graph_label"), [dataArrayReference], options);
Ref: #BrentM 's Answer Above
PS: I am using Flot Version prior to 0.8.1 so I dont have any idea about how latest version would work
