recently for my anycharts graph i used period and kept image in it
then in its click event i wrote some business logic and later i found that after click and executing business logic the Period is Highlighted as Orange How to get rid of this and its staying in the screen and its going after we click somewhere on the screen
do any one faced the same issue
here is the snap shapshot
of event code
private createChopPeriodObject(id: string, eventTime: Date, eventTimeMinuteValue: number,
noteText: string, userName: string): NoteEventPeriod {
return {
id: id,
start: eventTimeMinuteValue - 30000,
end: eventTimeMinuteValue + 30000,
label: { format: ''},
fill: {
src: 'assets/img/chop.png',
mode: 'fit'
},
stroke: 'none',
noteText: noteText,
userName: userName,
eventTime: eventTime,
eventTimeMinuteValue: eventTimeMinuteValue
} as ChopEventPeriod;
}
the Chop image is coming as orange upon clicking on it to invoke function
Chart elements support two states: normal and selected. You applied individual settings via data and it works well for a normal state. When a user clicks a period it switches to selected state appearance. In your case. the orange color is the default setting of the selected state.
Using the library API you can easily adjust state appearances. For details, check the sample.
The idea is to add only image source to the data and the rest of logic implement in a custom fill function that applies in normal and selected states.
This guide describes the idea of states. It's based on a Cartesian chart, but the idea is absolutely the same for Gantt charts.

I am coding in typescript react js and I have a highstocks graph. The problem I need help with is that I need to show the values on hover on tags (div boxes) above the graph individual to each series plotted within. The values coincide with wherever the cursor is on the graph. Please help me to achieve this.
I am attaching an image for better understanding. The dotted line on the image is where the cursor is at the moment and I want to show the values: [128.32, 49.94, 1.01] instead of '--' next to each tag name: ['Throttle Valve, Posi', 'Mill Hydr. Unit, Gri', 'Water Injection, Pos']. Thanks

Inside click events, you can access the nearest point using this.hoverPoint.
chart: {
events: {
click: function() {
console.log(this.hoverPoint)
}
}
},
Demo: https://jsfiddle.net/BlackLabel/8eym6jwo/
I was able to solve this problem. Appreciate everyone who helped out.
The solution (for getting an onclick point for multiple plotted series) is as follows:
this.hoverPoints?.map((item_hoverPoints, index_hoverPoints) => {
temp_trackValues[index_hoverPoints] = Number(
item_hoverPoints?.series?.points[this.hoverPoint?.index]?.y
).toFixed(3).toString();
});
Thanks
I have no react, typscript or d3 experience prior to this.
I am trying to build a horizontal bar chart where I can customize the colours of the bar depending on the value of the bar
I have gotten this far. See this chart:
I need to change the conditional formatting customization so the color is not entered from a drop down and is a text area where I can enter the hex code.
This is what I need to change and the condiditional formating I am talking about. It is on the table chart:
I have traced it back to the following code in controlPanel.tsx
{
label: t('Options'),
expanded: true,
controlSetRows: [
[
{
name: 'conditional_formatting',
config: {
type: 'ConditionalFormattingControl',
renderTrigger: true,
label: t('Conditional formatting'),
description: t(
'Apply conditional color formatting to numeric columns',
The actual pop up where you enter the field and color you want to associate the colour appears to be in
/superset/superset-frontend/src/explore/components/controls/ConditionalFormatingcontrol folder. So what I was hoping to do was to copy that, make my changes and call it. However I have no idea how I need to compile it and no idea how to call it
My guess was I could change the type below to the name of the copy of the component I created if I had compiled things correctly
name: 'conditional_formatting',
config: {
type: 'ConditionalFormattingControl',
Can anyone help me?
The available chart customization controls for a chart in superset set appear to be located in
/superset/superset-frontend/src/expore/components/controls
The list of chart customization controls exported that are available for list is in
/superset/superset-frontend/src/expore/components/controls/index.js
To customize one or to create a new component for customizing a custom chart in superset copy put in the directory listed above that you have copied and changed from the directory above or created and change the index.js file so that it is exported for use
I use ant design bar chart in my react project.
https://codesandbox.io/s/9qmjm0k7yw
Doc: https://pro.ant.design/components/Charts
I want to show the data with x-axis as date format (29/09/2018 for example). If I show like 30 days, it would not have enough space for all the label so it looks weird.
I want to hide the label of bar chart. Like this
if (more than 15 days) chart shows label
else hide label
Or is there any way that I show the chart for 30 days but only show the label for let's say 10 days?
How can I hide the label?
Unfortunately what you want to do is not supported by Antd-Pro Charts. It is stated in the docs that they designed the charts components with focus on ease-of-use over customization.
However Antd-Pro Charts are just a simplified subset of BizCharts (which itself is a port of G2) with reduced api options. If you need complicated chart options consider using the parent BizCharts library instead. You can do what you want by adjusting the < Axis > object in BizCharts.
In my example below, I have used a Column chart with x field of "week" and y field of "views". I did not want to display the label on the x field.
render() {
// console.log(this.state.data)
const config = {
data: this.state.data,
title: {
visible: true,
text: 'Your Stats',
},
xField: 'week',
yField: 'views',
meta: {
week: {
alias: " "
}
}
};
return (
<React.Fragment>
<Column {...config} />
</React.Fragment>
);
}
The data used is as follows:
Which yielded this outcome:
In order to develop your own project, I strongly recommend that you keep all of your software business in your own project, and use third party libraries just for their own business, rather than manipulating your software business because they simply change these libraries and To apply these changes, you may need to do a lot of work.
it does not only give you more performance but also increases your ability to develop.
for your topic, you can simply get an array and handle whatever you want and pass your processed array to component
I am stuck with an issue with react-slick. The subject line may not make sense, but I will try to explain the scenario in detail. See this example fiddle to see the issue in action.
var DemoSlider = React.createClass({
getSlides(count) {
var slides = [];
for(var i = 0; i < count; i++) {
slides.push((<img key={i} src='http://placekitten.com/g/400/200' />));
}
return slides;
},
render: function() {
var settings = {
dots: false,
infinite: false,
slidesToShow: 3,
slidesToScroll: 3
}
var slides = this.getSlides(this.props.count);
return (
<div className='container'>
<Slider {...settings}>
{ slides }
</Slider>
</div>
);
}
});
In this demo, initially the slider shows 20 slides (3 per page). The idea is that if you click the button, it will generate a random number, which would be the new number of slides. The code is fairly simple and self-explanatory.
To reproduce the problem,
1. keep on clicking Next arrow until you reach the last slide.
2. click on the button that says 'Click' to generate a new random number of slides.
My expectation was that the slide will go back to the first slide but not to stay on the page where it previously was. Even worse, if the new number of slides is lower than the previous number, the user will see a blank page with no slides. On clicking Previous error, he/she can go to the previous slides, and everything works normally but the initial display ruins the user experience.
Is there something I am missing to add in the code, or is this a bug?
Thanks,
Abhi.
I would say it is rather a buggy behavior, but still you can achieve what you want by forcing a redraw after new collection has been passed as props, by resetting react's key:
<DemoSlider key={Date.now()} count={this.state.count}/>
UPDATED FIDDLE
Quick workaround: When you change to a new set of slides, remove the component, and reconstruct it again. It would then start with the first slide. You can do this by incrementing the key attribute of DemoSlider.
For a proper fix, you'd need to tell the component to change the 'current slide', so that it's not looking at a slide index beyond the end, but a casual look at the source at https://cdnjs.cloudflare.com/ajax/libs/react-slick/0.11.0/react-slick.js suggests it currently does not allow this. A change would need to be made to InnerSlider.componentWillReceiveProps() to check state.currentSlide against props.slidesToShow and state.slideCount.
It would also benefit from allowing currentSlide to be passed as props.
I use kirjs/react-highcharts plugin for react but I have no idea how to get Highchart component in order to call reflow like: $('#container1').highcharts().reflow()
From docs its tells:
For access to methods & properties from the Highcharts library you can use ReactHighcharts.Highcharts. For example, the Highcharts options are available via ReactHighcharts.Highcharts.getOptions().
but I don't see there any reflow() method.
Any ideas?
Edit
its located under ReactHighcharts.Highcharts.charts so I can call
ReactHighcharts.Highcharts.charts[0].reflow()
but it has list of all highchart instances so I have no information what index is mine
I am using highcharts-react-official and highcharts. They are available via npm . Although I am using different packages, the working principle should be the same.
The way of using reflow() function in react-highchart is also Highcharts.charts[i].reflow(). I have prepared 2 code sandboxes for the demonstration. The first code sandbox shows the way of re-flowing every chart, and the second code sandbox shows the way of re-flowing a particular chart.
The first code sandbox link is here.
There is a button on App.js to hide and show highchart divs.
The child component is React.memo (for performance optimization), therefore the hidden highchart will not be auto resized after it becomes visible.
To let every chart window resize with respect to the window size. The following code is placed in App.js. It looks for all existing charts and re-flow them:
for (var i = 0; i < Highcharts.charts.length; i++) {
if (Highcharts.charts[i] !== undefined) {
Highcharts.charts[i].reflow();
}
}
The second code sandbox link is here.
Almost the same as the first code sandbox, but there is a ref array of referencing every chart.
The chart which needs re-flowing is placed with an id in its chart option.
Iterate every chart and get the index of the chart with that id e.g. "secondChart" for this example.
for (var i = 0; i < chartRef.current.length; i++) {
if (
chartRef.current[i].chart.userOptions.id !== undefined &&
chartRef.current[i].chart.userOptions.id === "secondChart"
)
Highcharts.charts[chartRef.current[i].chart.index].reflow();
}
Re-flow that chart.
The Reflow can be set with event load in options.
Workaround: You have to set reflow() using setTimeout() this will trigger the resizing. Time is set to 0 to avoid delay.
Solution
const options = {
chart: {
type: 'column',
style: {},
events: {
load() {
setTimeout(this.reflow.bind(this), 0);
},
},
},
title: 'Column Chart',
}
Usage
<HighchartsReact highcharts={Highcharts} options={options} />
