Now the blue line is equal to the height of the graph
Please tell me how to make the line start from the marker to the bottom line x
I will be glad for any help
I do not think you can do this with simple configuration. However, since ApexCharts is based on SVG, you can manipulate the DOM yourself quite easily.
As I said previously in other answers, because I have already used this technique several times, what I am going to show you is more experimental than official.
It works, though.
In your case, the idea is to put some code in the mouseMove event callback. The use of a MutationObserver is recommended to watch for changes in the DOM. When a marker (which is a circle) is hovered, its r, cx and cy attributes are updated. In particular, cy is the most interesting because it gives us the vertical position of the active marker. r is also useful to adjust the offset of crosshairs.
Here is the main part of the code:
chart: {
// ...
events: {
mouseMove: () => {
let crosshairs = document.querySelector('.apexcharts-xcrosshairs'),
marker = document.querySelector('.apexcharts-marker');
let settings = { attributes: true },
observer = new MutationObserver(() => {
crosshairs.setAttribute('y1', `${marker.cy.baseVal.value + marker.r.baseVal.value + 1}`);
});
observer.observe(marker, settings);
}
}
},
Here is the full code:
const data = [45, 52, 78, 45, 69, 23, 30, 45, 52, 88];
const dataXCategories = ["10.12", "11.12", "12.12", "13.12", "14.12", "15.12", "16.12", "17.12", "18.12", "19.12"];

observer = new MutationObserver(() => {
crosshairs.setAttribute('y1', `${marker.cy.baseVal.value + marker.r.baseVal.value + 1}`);
});
observer.observe(marker, settings);
}

Anyone here can help me how to change the color of a needle in my speedometer chart? I copied this chart in Apache E-charts.
This is the script:
var dom = document.getElementById('performance-chart');
var myChart = echarts.init(dom, null, {
renderer: 'canvas',
useDirtyRect: false
});
var app = {};
var option;
option = {
series: [
{
type: 'gauge',
progress: {
show: true,
width: 18,
itemStyle: {
borderWidth: 10,
color: '#8D7CDB'
}
},
axisLine: {
lineStyle: {
width: 18
}
},
axisTick: {
show: false
},
splitLine: {
length: 5,
lineStyle: {
width: 1,
color: '#8D7CDB'
}
},
axisLabel: {
distance: 25,
color: '#8D7CDB',
fontSize: 9
},
anchor: {
show: true,
showAbove: true,
size: 25,
color: '#8D7CDB',
itemStyle: {
borderWidth: 8,
borderColor: '#8D7CDB'
}
},
title: {
show: false
},
detail: {
valueAnimation: true,
fontSize: 20,
color: '#8D7CDB',
formatter: "{value}%",
offsetCenter: [0, '70%']
},
data: [
{
value: 5.85
}
]
}
]
};
if (option && typeof option === 'object') {
myChart.setOption(option);
}
window.addEventListener('resize', myChart.resize);
The 'needle' is represented by the pointer parameter. Like most of echarts items, you can change the pointer style with itemStyle.
series: [
{
type: 'gauge',
... // the rest of the config
pointer: {
itemStyle: {
color: 'red'
}
},
},
]

there is example that i used https://www.highcharts.com/demo/dynamic-master-detail
Adding a new series to a master-detail chart is very simple. You need to only add a new data set and connect it to the right series. For example:
var detailData = [
[],
[]
],
detailStart = data1[0][0];
masterChart.series.forEach((s, index) => {
s.points.forEach(point => {
if (point.x >= detailStart) {
detailData[index].push(point.y);
}
});
});
// create a detail chart referenced by a global variable
detailChart = Highcharts.chart('detail-container', {
chart: {
type: 'area',
...
},
...,
series: [{
data: detailData[0]
}, {
data: detailData[1]
}]
});

I have the following html:
<div id="test" ui-jq="plot" ui-options="
[
{ data: {{line}}, points: { show: true, radius: 6}, splines: { show: true, tension: 0.45, lineWidth: 5, fill: 0 }, label: 'Akademi' },
],
{
colors: ['{{app.color.info}}', '{{app.color.success}}'],
series: { shadowSize: 3 },
xaxis:{
font: { color: '#ccc' },
position: 'bottom',
ticks: {{categories}}
},
yaxis:{ font: { color: '#ccc' } },
grid: { hoverable: true, clickable: true, borderWidth: 0, color: '#ccc' },
tooltip: true,

redrawOverlayInterval: 60
}
" style="height:240px">
</div>
The data for this chart is being loaded by a $http get request:
$http.get(api.getUrl('latestActivityByTeamAndModule', [$scope.team_id, $scope.module_id]))
.success(function(response){
var i = 0;
$scope.line = [];
$scope.categories = [];
response.forEach(function(y){
var log_date = y.date.substr(0, y.date.indexOf('T'));
var date = new Date(log_date);
var logg_date = moment(date).fromNow();
$scope.categories.push(logg_date);
$scope.line.push(y.num_taken);
});
});
Sadly when i force reload (F5) the chart is empty. HOWEVER the html is correctly updated:
From inspecting the element in chrome:
<div id="test" ui-jq="plot" ui-options="[
{ data: [4], points: { show: true, radius: 6}, splines: { show: true, tension: 0.45, lineWidth: 5, fill: 0 }, label: 'Akademi' },
],
{
colors: ['#23b7e5', '#27c24c'],
series: { shadowSize: 3 },
xaxis:{
font: { color: '#ccc' },
position: 'bottom',
ticks: ["21 hours ago"]
},
yaxis:{ font: { color: '#ccc' } },
grid: { hoverable: true, clickable: true, borderWidth: 0, color: '#ccc' },
tooltip: true,
tooltipOpts: { content: '%x.1 is %y.4', defaultTheme: false, shifts: { x: 0, y: 20 } },
redrawOverlayInterval: 60
}" style="height: 240px; padding: 0px; position: relative;">
im guessing its because of the lazy load so that it does not redraw on the data change?
Try adding ui-refresh
<div id="test" ui-jq="plot" ui-refresh="line" ui-options="[{ data: {{line}}, ... }, ... ]"></div>
Where ui-refresh value is the literal name of ui-options data value name.
I have a Flot graph which I am trying to make it so that when you click a particular legend item it makes that data disappear from the chart.
I am having limited success in getting this to work. I've gotten as far as being able to click a legend item and a series line is removed, but not the points, and it appears to be the wrong line data as well.
Any help on this would be really appreciated :)

You must be tired, you just have an off-by-one error, and you only called the update for the lines, not the points.
togglePlot = function(seriesIdx)
{
var previousPoint2 = plot_statistics.getData();
seriesIdx--; // ***HERE***
previousPoint2[seriesIdx].points.show = // ***AND HERE***
previousPoint2[seriesIdx].lines.show = !previousPoint2[seriesIdx].lines.show;
plot_statistics.setData(previousPoint2);
plot_statistics.draw();
}
