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...

Re: syncing resizing of multiple series in same pane

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...

Re: Angular Jasmine Karma test failing with Highcharts-more plugin

Hi, welcome to our forum and thanks for contacting us with your issue! To make sure that it actually a missing (or incorrectly loaded) highcharts-more module is a culprit, could you change the series' type to one of the basic ones, e.g. column , and see if the tests work fine?

bhagyaMazire,

I'm sorry but I'm still not able to reproduce your issue. Have you tried to put your chart into the above jsFiddle demo? To find the cause and suggest a potential solution, I need to see the problem first.

Re: Different line style and/or line width for the high/low lines of a range series

I came up with another idea: how about disabling the line for areasplinerange (lineWidth: 0) and now adding 2 fake series instead of only 1?

Re: Scrolling the stacked column chart from left to right breaks the chart for large data

It seems the problem here is that you're trying to plot exactly 14112 points - it's too much for Highcharts and browser to handle. I suggest using the boost module (the chart works much faster), but you lose some features, e.g. dataLabels. See demo: https://jsfiddle.net/BlackLabel/xjwtsrch/ Using th...

Re: Different line style and/or line width for the high/low lines of a range series

It seems to be much more complicated than I thought... I thought those lines are separate SVG elements and it will be easy to change the color of each of them. It turned out it's one graph path and it's not easy to separate it (probably impossible with a current implementation). See a DOM element: a...
