  1. When a value is coded null in a map, it is not displayed in the tooltip. I usually code missing values with null values (null), not zero values (0).
    See https://jsfiddle.net/martindfurrer/xakgs53o/9/

    I propose to allow null values in map, mabbubble and mappoint graph types, and display them in the tooltip and data labels, similar to what is already possible in heatmap graphs, for example.

    This would elegantly allow to distinguish null values from zero values, and display them correctly.

  3. If you have 3 stacked series each with a value of 10, using point.y will show 10,10, and 10 in the tooltip. It should instead show 10,20,30. It seems that point.y and point.value are the same thing

  5. When we create a chart the axis take in account the values of min, max and/or our series.

    But if we try to call .update() the tickPositions and tickInterval are not recalculated, neither when we didn't set those configs on the creation.

  7. Currently, if two nodes of a network-type graph are connected by multiple edges (or links), only the last of these links in the data series will be displayed, as it will appear on top of all others.

    This is problematic in a case where a network graph should include multiple links of different styles, e.g. different colors, line styles, with different link labels, etc.

    See example jsfiddle, where a solid teal and dotted red link are obscured by a solid red one :

    https://jsfiddle.net/pqvemxsb/1/

    Because all links are straight lines and their shape cannot be changed, it appears impossible to…

  9. I would see two ways of doing that. The first one, the most obvious (but maybe not the most straitghtforward for you guys) would be to let users enable the boost module on network graph to allow rendering on GPU.
    The alternative would be to allow to generate the graph asynchronously in the background so it's not blocking and only display it when ready.
    Best regard to the team and keep the good job !

  10. The general suggestion here is to manage a project using task dependencies and durations rather than dates. The simplest enhancement would be to default a task start date to the end of the dependency task. This is the ASAP assumption. It should then be possible to specify the task duration rather than an end date. Next it would be nice to specify the task start as a duration before or duration after a dependency task end date. There are other assumptions (e.g. as late as possible), but ASAP is the most common. Critical path highlighting would also be useful.

  13. Highstock: Step line connects data with vertical lines. In order to visualize climatological norm values being able to simply depict a horizontal line for one data point would be handy. Could be realized with a step line chart that hides vertical lines.

  14. In trying to create graphs with Highcharts, I've found that once a graph gets sized small enough (though still reasonably sized that its not uncommon), the axis usually only gives out 1 single tick mark value.

    I want to avoid single tick marks, because with only 1 tick mark, a person viewing the graph loses the sense of scale that comes with multiple tick marks which specifies a physical distance on the graph as a range of numbers.

    Id like to see a minTickAmount option added to the Axis, such that specifying it prevents Highcharts from trying to give an…

  15. I would like to fill a space between two lines that generally move up and down, but sometimes one is above the other, and sometimes the other way. And I'd like the fill colour to reflect which line is on top.

    Take the following as an example.

    https://jsfiddle.net/xczdfkjf/1/

    Where the lower and upper ends of the range cross over, between 6 Jul and 7 Jul, I'd like the fill colour to change.

    I originally posted this question here back in 2016, and have seen similar questions/requests, but still in 2021 it is not possible :( https://stackoverflow.com/q/41292433/4070848

  16. Currently, the entire data series is being exported to excel instead of selected custom range by navigator. Image and pdf formats are working fine.

    Is there any way to export only current plotted series to excel?

  18. Using highchart exporting module, excel is downloaded always with the workbook name ARK1. It would be having flexibility/configuration property for users to set workbook title.
