Highmaps scroll down when page load - Angular SPA - angularjs

I m developing report page. In this page I m using highcharts and highmaps together. At first load there is no more problem but when user click the another page, then back to again this report page highmaps area scroll down.
I have single page application, so every link using ajax call.
I found this solution, but this way I cannot store any rootscope element. Also I dont want to use cookies or localstorage.
$('#mapsmaps').highcharts('Map', {
title : {
text : 'City Lived',
style: {
color: '#008bff'
}
},
subtitle : {
text : ''
},
legend: {
title: {
text: ' ',
style: {
color: (Highcharts.theme && Highcharts.theme.textColor) || 'black'
}
},
floating: true,
valueDecimals: 0,
valueSuffix: '',
backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColor) || 'rgba(255, 255, 255, 0.85)',
symbolRadius: 0,
symbolHeight: 10,
},
mapNavigation: {
enabled: false,
buttonOptions: {
verticalAlign: 'bottom'
}
},
tooltip: {
// backgroundColor: 'none',
// borderWidth: 0,
// shadow: false,
useHTML: true,
padding: 0,
pointFormat: '<span class="f32"></span>'
+ ' {point.name}'
},
colorAxis: {
dataClasses: [{

color: "#5FA08F"

}, {

}]
},

Any one can suggest solution for it.

React Apexchart

How to correctly display large amount of data on ReactApexChart , Bar Chart. At image below, I am passing 552 entries. When amount of entries under 50 everything displays just fine, above this number starts look like a hell and performance is getting low. I am using React Js Class Component.
this.state = {
series: [{
name: props.name,
data: props.chartValue,
}, ],
options: {
grid: {
row: {
colors: ["#D6EAF8 ", "#D6EAF8"],
},
},
chart: {
type: "bar",
height: 350,
},
plotOptions: {
bar: {
borderRadius: 4,
horizontal: true,
colors: {
ranges: [{
from: 0,
to: Number.MAX_VALUE,
color: "#29ABE2",
}, ],
backgroundBarColors: [],
backgroundBarOpacity: 1,
backgroundBarRadius: 0,
},
},
},
dataLabels: {
enabled: true,
formatter: function(val) {
return val + ` min`;
},
offsetX: 15,
style: {
fontSize: "12px",
colors: ["#FFFFFF"],
},
},
xaxis: {
categories: props.ids,
labels: {
style: {
colors: [],
fontSize: "15px",
fontWeight: 500,
},
},
},
yaxis: {
categories: props.differenceInTime,
labels: {
style: {
colors: [],
fontSize: "15px",
fontWeight: 500,
},
},
axisTicks: {
show: true,
borderType: "solid",
color: "#78909C",
width: 10,
offsetX: 0,
offsetY: 0,
},
},
},
};
<div id="chart">
<ReactApexChart options={this.state.options} series={this.state.series} type="bar" />
</div>
Here is 552 entries
why put max integer for the colors? That could be a performance issue
ranges: [{
from: 0,
to: Number.MAX_VALUE,
color: "#29ABE2",
}

Highchart: Break y-axis doest work in react app but is working in js fiddle

I reproduce your code in the React environment and everything looks fine, same as in the jsFiddle.

Highcharts Showing negative values on tooltip

I have set min:0, in y-axis. But in tooltip i want to show negative values also and also it should start with value y=0 only.
if i will remove min:0 in y axis it will show negative values with tooltip in chart. But i only want to see negative values on tooltip not on chart.
but it is not allowing me to show negative values.
below is sample code.
$(id).highcharts({
chart: {
zoomType: 'xy',
marginLeft: 45,
marginRight: rightval - 10
},
title: { text: title },
exporting: { enabled: false },
credits: { enabled: false },
legend: { enabled: false, align: 'left', x: 10, verticalAlign: 'bottom', y: 3, shadow: false },
xAxis: {
min: minimum,
max: maximum,
scrollbar: {
enabled: scroobarVal
},
fontWeight: 'bold',
categories: Data['categories'],
labels: {
y: 20,
rotation: 0,
style: {
color: 'gray',
//fontSize:'1px !important;'
}
}
},
yAxis: [{
min: 0,
allowDecimals: false,
endOnTick: false,
gridLineWidth: 0,
labels: {
formatter: function () {
if (optionSelected == 'Day') {
return this.value;
} else {
return this.value / 1000000 + 'M';
}
},
style: {
color: '#767676'
}
},
offset: -10,
title: {
text: 'Inv ' + val_qty,
"textAlign": 'top',
"rotation": 0,
x: 60,
y: yaxisVal,
style: {
color: '#767676',
fontWeight: 'bold'
}
}
}, {
allowDecimals: false,
min: 0,
endOnTick: false,
gridLineWidth: 0,
title: {
text: y2axisname,
"textAlign": 'top',
"rotation": 0,
x: -75,
y: yaxisVal,
style: {
color: '#767676',
fontWeight: 'bold'
}
},
offset: -10,
labels: {
format: '{value}',
style: {
color: '#767676'
}
},
opposite: true
}],
labels: {
items: [{
html: ' ',
style: {
color: (Highcharts.theme && Highcharts.theme.textColor) || 'black'
}
}]
},
tooltip: {
style: { fontSize: '7pt' },
formatter: function () {
var s = '<b>' + this.x + '</b>';
$.each(this.points, function (i, point) {
s += '<br/><span style="color:' + point.series.color + '">\u25CF</span> ' + point.series.name + ': <b>' + CurrencySymbol + '</b>' + point.y.toString().replace(/,/g, "").replace(/\B(?=(\d{3})+(?!\d))/g, ", ");
});
return s;
},
shared: true
},
series: Data['series'],
});
I don't think there is a simple way to do this on Highchart.
One hacky way I found (don't judge me!) is to have a "ghost" series and set the tooltip.shared option to true.

React Highstock Won't Work But Highchart works

I would like to switch from React Highcharts to React Highstock because of the compare option I would like to use in Highstock. Here is my config:
var config = {
credits: {
enabled: false
},
title: {
text: '' // No Title
},
chart: {
height: 200,
type: 'line',
backgroundColor: 'rgba(155, 255, 255, 0.0)' // Always transparent Background
},
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.y}</b> ({point.change}%)<br/>',
valueDecimals: 2,
split: true
},
yAxis: {
labels: {
format: '$ {value}' // Always Money
},
title: {
text: '' // No Label
}
},
xAxis: {
type: 'datetime',
labels: {
format: '{value:%Y\'%b}'
},
tickInterval: getTickInterval(this.props.interval),
},
plotOptions: {
series: {
color: transformColor(this.props.color),
lineWidth: 1,
compare: 'percent',
showInNavigator: true
},
line: {
marker: {
enabled: false
}
}
},
legend: {
layout:'vertical',
align: getLegendPosition(this.props.legend).align,
verticalAlign: getLegendPosition(this.props.legend).verticalAlign,
x: getLegendPosition(this.props.legend).x,
y: getLegendPosition(this.props.legend).y,
floating: true,
itemStyle: {
font: 'sans-serif',
fontWeight: 'bold',
fontSize: '9px'
},
symbolHeight: 10,
symbolWidth: 10
},
series: this.props.series
};
return (
<div>
<ReactHighcharts config={config}/>
</div>
)
}
But when I switch to Highstock:
return (
<div>
<ReactHighstock config={config}/>
</div>
)
It gives me an error:
InvalidCharacterError: Failed to execute 'createElement' on 'Document': The tag name provided ('/static/media/Highstock.a88db6d5.jsx') is not a valid name.
Any ideas?
Nevermind, don't actually use the React-Highstock npm package. Just do this:
const ReactHighstock = require('react-highcharts/ReactHighstock');
