Secondary Axis to Scale on Chart - javascript

I am trying to get both lines on my chart to scale correctly, I have read through the documentation but can't seem to find how to do this.
images
The above image shows what happens to the orange line when a secondary axis is added. It's like they are using the same scale rather than their own.
I currently have the below code:
$(function(e) {
/*-----echart1-----*/
var options = {
chart: {
height: 300,
type: "line",
stacked: false,
toolbar: {
enabled: false
},
dropShadow: {

opacity: 0.1,
},
},

dataLabels: {
enabled: false
},
stroke: {

},
grid: {

},

Hightchart issue, when more then one plot is used on page

I am working on page, where i need to have multiple plots, one being a solid gauge and the other being a line graph.
I am using the Ionic Framework 5 with angular and High Charts.
I am finding that when one plot is displayed, it works fine, but with more then one I am getting some type of conflict where the line chart does not get updated and the gauge gets data which is meant for the line graph.
This my code. Do i need to do anything in perticular?

ApexCharts: Line graph overflowing out of Y axes

Hope you guys are doing okay.
I am working on a line graph from Apex Charts and every thing seems to be working fine except one issue.
The lines cross-over/overflows on the y axes whereas they are supposed to stay between the y axes. I have tried adding offsetX to almost everything but it just doesn't seem to work.
What is it that I am doing wrong here? How can I fix it?
Here's CODEPEN.
Here's an image of the issue:
Here's the snippet:
const lineChartEl = document.querySelector('#line-chart');

You can fix it by removing padding inside grid options:
const lineChartEl = document.querySelector('#line-chart');
const lineChartOptions = {
chart: {
height: '380',
width: "100%",
type: "line",
dropShadow: {
enabled: true,

apexcharts.js always display a set amount of horizontal lines

I created the same apexchart with 2 different datasets. Chart 1 looks great with horizontal lines. But chart 2 has just 1 horizontal line.
The only difference between chart 1 and chart 2 is the dataset. How can I always display 5 horizontal lines across the chart?

It is showing on both charts, only that on the second it is only showing one. This is because the tick amount of the y-axis is calculated automatically depending on the data, but you can set it using tickAmount:

Flot Charts. Custom color below x-axis value

I have a Flot Bar Chart code.
$(function() {
var barOptions = {
series: {
bars: {
show: true,
barWidth: 0.4,
fill: true,
fillColor: {
colors: [{
opacity: 0.8
}, {
opacity: 0.8
}]
}
}
},
xaxis: {
mode: "categories",
tickLength: 0
},
yaxis: {
min:-200, max: 200, tickSize: 50,
},
colors: ["#1ab394"],
grid: {
color: "#999999",
hoverable: true,
clickable: true,
tickColor: "#D4D4D4",
borderWidth:0
},
legend: {
show: false
},
tooltip: true,
tooltipOpts: {
content: "Cost: %y %"
}
};
var barData = {
label: "bar",
data: [
["First", -100],["Second", 66.67],["Third", -177.77],]
};
$.plot($("#flot-bar-chart"), [barData], barOptions);
});
I want that every bar below 0 would be specific (for example red) color. I have tried to do that with threshold plugin, but it adds additional values. Is there any solution to make it?
The threshold plugin should not add additional values, see this fiddle or the snippet below:
$(function() {
var barOptions = {
series: {
bars: {
show: true,
barWidth: 0.4,
fill: true,
fillColor: {
colors: [{
opacity: 0.8
}, {
opacity: 0.8
}]
},
align: 'center'
}
},
xaxis: {
mode: "categories",
tickLength: 0,
ticks: [
[1, 'First'],
[2, 'Second'],
[3, 'Third']
]
},
yaxis: {
min: -200,
max: 200,
tickSize: 50,
},
colors: ["#1ab394"],
grid: {
color: "#999999",
hoverable: true,
clickable: true,
tickColor: "#D4D4D4",
borderWidth: 0
},
legend: {
show: false
},
tooltip: true,
tooltipOpts: {
content: "Cost: %y %"
}
};
var barData = {
label: "bar",
data: [
[1, -100],
[2, 66.67],
[3, -177.77],
],
threshold: {
below: 0,
color: "rgb(200, 20, 30)"
},
};
$.plot($("#flot-bar-chart"), [barData], barOptions);
});
#flot-bar-chart {
height: 300px;
}

Add Values to data under series dynamically - echarts

I have created a Bar graph using echarts. I want to bind multiple values to data object dynamically, currently I'm able to bind only single value. here is my java script. I'mm a newbie for this, hoping for a fully functional solution.
var myChart = echarts.init(document.getElementById('page_views_today'));
var option = {
// Setup grid
grid: {
zlevel: 0,
x: 20,
x2: 40,
y: 20,
y2: 20,
borderWidth: 0,
backgroundColor: 'rgba(0,0,0,0)',
borderColor: 'rgba(0,0,0,0)',
},
// Add tooltip
tooltip: {
trigger: 'axis',
axisPointer: {
type: 'shadow', // line|shadow
lineStyle: { color: 'rgba(0,0,0,.5)', width: 1 },
shadowStyle: { color: 'rgba(0,0,0,.1)' }
}
},
// Add legend
legend: {
data: []
},
toolbox: {
orient: 'vertical',
show: true,
showTitle: true,
color: ['#bdbdbd', '#bdbdbd', '#bdbdbd', '#bdbdbd'],
feature: {
mark: { show: false },
dataZoom: {
show: true,
title: {
dataZoom: 'Data Zoom',
dataZoomReset: 'Reset Zoom'
}
},
dataView: { show: false, readOnly: true },
magicType: {
show: true,
itemSize: 12,
itemGap: 12,
title: {
line: 'Line',
bar: 'Bar',
},
type: ['line', 'bar'],
option: {
/*line: {
itemStyle: {
normal: {
color:'rgba(3,1,1,1.0)',
}
},
data: [1,2,3,4,5,6,7,8,9,10,11,12]
}*/
}
},
restore: { show: false },
saveAsImage: { show: true, title: 'Save as Image' }
}
},
// Enable drag recalculate
calculable: true,
// Horizontal axis
xAxis: [{
type: 'category',
boundaryGap: false,
data: [
'0h-2h', '2h-4h', '4h-6h', '6h-8h', '8h-10h', '10h-12h', '12h-14h', '14h-16h', '16h-18h', '18h-20h', '20h-22h', '22h-24h'
],
axisLine: {
show: true,
onZero: true,
lineStyle: {
color: 'rgba(63,81,181,1.0)',
type: 'solid',
width: '2',
shadowColor: 'rgba(0,0,0,0)',
shadowBlur: 5,
shadowOffsetX: 3,
shadowOffsetY: 3,
},
},
axisTick: {
show: false,
},
splitLine: {
show: false,
lineStyle: {
color: '#fff',
type: 'solid',
width: 0,
shadowColor: 'rgba(0,0,0,0)',
},
},
}],
// Vertical axis
yAxis: [{
type: 'value',
splitLine: {
show: false,
lineStyle: {
color: 'fff',
type: 'solid',
width: 0,
shadowColor: 'rgba(0,0,0,0)',
},
},
axisLabel: {
show: false,
},
axisTick: {
show: false,
},
axisLine: {
show: false,
onZero: true,
lineStyle: {
color: '#ff0000',
type: 'solid',
width: '0',
shadowColor: 'rgba(0,0,0,0)',
shadowBlur: 5,
shadowOffsetX: 3,
shadowOffsetY: 3,
},
},
}],
// Add series
series: [
{
name: 'Page Views',
type: 'bar',
smooth: true,
symbol: 'none',
symbolSize: 2,
showAllSymbol: true,
barWidth: 10,
itemStyle: {
normal: {
color: 'rgba(63,81,181,1.0)',
borderWidth: 2, borderColor: 'rgba(63,81,181,1)',
areaStyle: { color: 'rgba(63,81,181,1)', type: 'default' }
}
},
data: []
}
]
};
Here is my java-script function from where I want to bind the values dynamically.
// Load data into the ECharts instance
load_graph_with_positions(option);
function load_graph_with_positions(option) {
option.series[0].data[0] = 1234;
myChart.setOption(option);
}
One way to do this is by passing values in an array and then shifting the previous values, while pushing-in the data. Following is the example of shiting and pushing the data:
option.series[0].data.shift();
option.series[0].data.push(json.num);
Hence your function will become:
function load_graph_with_positions(option,values) {
var valuesLength = values.length;
for (var i = 0; i < valuesLength; i++) {
option.series[0].data.shift();
option.series[0].data.push(values[i]);
}
myChart.setOption(option);
}
You can also refer to following github example for dynamic addition:
