Re: Heatmap rending is slow for Million Data Points

Hi Kishore, the same results as for a standard or boosted chart with >100k points could be achieved by processing the data and getting a smaller data sample and using heatmap with interpolation (https://www.highcharts.com/demo/highcharts/heatmap-interpolation) that would help with reducing the amoun...

Re: Reducing size of inline SVG path for maps

Looks like a different, but connected, problem - reported a bug here: https://github.com/highcharts/highcharts/issues/18972 This could be resolved by parsing the SVG path in JS code after it is loaded into the page so you could still have the option to load a smaller file for the map. The conversion...

Re: Reducing size of inline SVG path for maps

Hi, The operators are working better now but the script that is processing the path is not handling the lack of spaces between path elements (mostly or only the lack of space before the minus sign when numbers are given as e.g. "19-69" instead of "19 -69"). If there are spaces added in between each ...

Re: HighMaps Zoomed-in Location based on user selected location

Hi Ferdy, To zoom to a map point you could call zoomTo function on the point. Demo: https://jsfiddle.net/BlackLabel/6430wnrj/16/ If your point has id then you could use chart.get function to find that point. chart.get('NY').zoomTo(); zoomBy coords parameter is just a set of coordinates that should b...

Re: Reducing size of inline SVG path for maps

There are some limitations for the path value, namely "For compatibily with old IE, not all SVG path definitions are supported, but M, L and C operators are safe." (source: https://api.highcharts.com/highmaps/series.map.data.path). There is currently a work being done towards removing any old IE dep...

Re: Reducing size of inline SVG path for maps

Hello, Why the resulting path is not supported? Please provide more details and a file/code example. In general, the size of the same map in SVG is larger than in GeoJSON and TopoJSON is the smallest. By size: SVG > GeoJSON > TopoJSON If the map that you have is having a lot of small parts you could...

You got it to work so below is a short answer purely to leave no unanswered questions: Formatting of the map files for dilldown includes name property for each data point (so the breadcrumbs show correct text) and something useful on drilldown property (f...

Re: Can't get drilldown map to work with custom GeoJSON file

Hi, Is Highmaps limited to the Map collection files? No, it is not. Let's start with how the working map works - it boils down to some key pieces. The map of the USA has each state with some properties. One of the properties is 'hc-key'. Using the 'hc-key' property we can find a map of that state in...

Re: Cluster Expansion when there are multiple points at the same lat/long

Hi mchaggis If you have multiple points with the same location you could limit the maximum zoom using maxZoom to avoid zooming too much. I have managed to write a work round where the tooltip formatter function detects is a cluster contains only points with the same lat/long and prevents the user fr...

Re: Pacific Centered World Map (Bubble Map)

Based on a rotation 's lambda option any part of the world could be used as a center. With lambda of 210 it looks like here: https://jsfiddle.net/BlackLabel/p5or2gfe/ Code reference: mapView: { projection: { name: 'Miller', rotation: [210] } }, You could also see this in action with GUI for rotation...
