Re: How to load series data from fetch JSON data using React Native Functionnal Components ?

Each Highcharts is separate webview. So if you need to have 10 separate charts with 10 different data sources you should use 10 declaration of directive.

Could you paste your code of an App to test your unworking case?

Re: Using Hightchart for React Native App

In the chartOptions you need to declare options for requested chart instead of demo data. Please replace these lines: chartOptions: { chart: { events: { load: function () { // set up the updating of the chart each second var series = this.series[0]; setInterval(function () { var y = Math.random(); s...

Re: BEFORE:AFTER Plot-variable name/change selected from DDs

In can be realized in this way, but please be aware that it is complex solution. 1. Create the right name of V (by contacting strings from point 1) based on inputs and selects in the form. 2. Load CSV file, parse in a custom way (Extracting the right column) - docs about loading and parsing data fro...

Re: What to do when data is missing

Highcharts are not able to predict data, but in the Highstock we implemented "ordinal" option, which should fit to your scenario. I advise you to test.

Re: how show array in pie-basic with MySQL?

I think that better is separate PHP code and Javascript. You can communicate backend (PHP) with front by JSON.

To do that create an array of data in PHP and return it by json_encode() method.

In javascript use ajax (i.e $.getJSON()) and load data from url and init a chart.

Re: On click of yAxis title replace it with a new yAxis.

Hi Shantiswarup,
By default click event is not supported on axis' title, but you can use an extension, custom-events, which allows you to do that.

Re: Hidden column dataLabel

Hi Jeffrin,
By default it works only in bars with non-rotated datalabels, but I prepared you a simple snippet of code which detects "no enough space" for datalabel and move it down.

Re: Downsampling/grouping on clustered datasets

Do you have disabled ordinal parameter for xAxis?

Could you replicate your example as live demo on the jsfiddle.net? It will allow us to debug it.

Re: Explicit call for column to resize it width

Hi,
I advise you to set pointRange parameter which calculates width dynamically.
