Re: How to prevent Treegraph nodes and data labels from overlapping

Yes, the default height of the Highcharts' charts is 400px. You can either change it in CSS: https://jsfiddle.net/BlackLabel/8mh0yx7o/ Or in the chart's config: https://jsfiddle.net/BlackLabel/wbmhyv16/ Do you know the node's height? If you'd like to have a static node height (I set it using. series...

Re: How to prevent Treegraph nodes and data labels from overlapping

Hi again!

I guess you forgot to attach your image. Could you please provide one? An online jsFiddle (or codesandbox) demo of your chart would be perfect.

Thanks in advance!

Re: Using Treegraph in React: How to disable default node expand/collapse click behavior

Hi! Thanks for reaching out to us with your question. Usually, e.preventDefault() and e.preventPropagation should do the job, not sure why it didn't work this time. But you can always disable the point.toggleCollapse() method responsible for the expand/collapse logic by overriding it with an empty f...

Re: Multiple horizontally aligned charts

Hi biross, Welcome to our forum! Yes, you can use 2 separate containers with 2 separate charts, use only one shared legend and fire the series.show() and series.hide() methods on the series you'd like to connect and show/hide together.

Re: Need a chart type with xrange/width and y column support

Hi zztop1! Welcome to our forum! Did you consider the 'polygon' series type? You can define points as rectangles with both x and y ranges defined: https://jsfiddle.net/BlackLabel/xmsup9bz/ Of course, it will require a bit of data parsing, but it should be really straightforward. More features like p...

Re: How can I set a background color from a timespan?

Hi, Highcharts doesn't provide it by default from API, but you can achieve this by adding additional xAxis and yAxis, manipulating their height and top position and assigning an xrange series to it. To add multiple bars, you can add multiple axes/series. To split your bar into 2 colors, you can use ...

Re: How to scale and resuse Highcharts code

Hi Thiago!

Welcome to our forum!

Your question is very general, could you elaborate? Do you have any specific questions about the Highcharts usage?
By saying "scaling" do you mean removing unnecessary chart's elements like e.g. titles/labels/legend?

Best regards!

Re: How can I set a background color from a timespan?

Hi! Welcome to our forum and thanks for contacting us with your question. I'm not sure If I understood you well. In your dashboard, are you trying to add multiple separate charts where one of them will be a bar chart that occupies 100% width of a time frame? Let's take this simple xrange series as a...

Re: Using live data in Highcharts Editor

Hi! Welcome to our forum. Thanks for choosing Highcharts, I hope you'll like it. First of all, when feeding Highcharts with objects, the basic line data in Highcharts should be in the format of { x: datetime/number, y: number } , not { time: datetime/number, T_SFC: number } (the properties names sho...

Re: The data label on the bar is not shown for some legends on hover of the legend in the stacked column chart

Hi! When you're using large data (higher than https://api.highcharts.com/highcharts/series.column.boostThreshold]series.boostThreshold ), the boost module kicks in - see more info about the boost module and its limitations:https://www.highcharts.com/docs/advanced-chart-features/boost-module Some of ...

Re: Percentage value is shown as undefined for large data in stack column charts.

Hi there! This is strange having this working in 10.0.0... Not working demo in v7.2.1: https://jsfiddle.net/BlackLabel/y1s32x7q/ Also not working demo in v10.0.0: https://jsfiddle.net/BlackLabel/bupcz80x/ This is caused by the boost module striping down some point's options (removes point.percentage...

Re: Observing memory leak when multiple charts are rendered on screen and are updated on refresh interval say 5 seconds.

Hi! I created a demo with 100 pies updated every 5 seconds and the accessibility module enabled in v10.0.0: https://jsfiddle.net/BlackLabel/08jbsu2o/ After 45 minutes I haven't noticed any memory leak. In Chrome Developer Tools memory used was 20MB all the time with no suspicious objects. I'm afraid...

Hi @dizzy! 1. You can use yAxis.resize.controlledAxis for this: https://api.highcharts.com/highstock/yAxis.resize.controlledAxis , see demo: https://jsfiddle.net/BlackLabel/x5zth7oy/ 2. It's hard to say without seeing a live demo. Are you able to share one? 3. Yes, set tooltip.shape and optionally t...
