  1. When I move my mouse ("zoomType=x" enabled chart) over the data, the x-crosshair seems to snap to the datapoints. there should be a way to either:

    1. turn off the "auto-snapping" function
    2. disable/hide the "x-crosshair" when a "zoomSelection" or "mousedown" event takes place and then enable/show it after a "mouseup"?
    3. snap the "selection start/end" to the "snapped-datapoint"

    Any one of these solutions or any other suggestion would be great!

  3. I need to increase the size of the tracker element in column points. The chart doesn't seem to handle mouse events properly when using very small columns.

  7. The tooltip.formatter() supports some HTML entities, e.g. <b>, but it doesn't support named or numbered entities.
    For example, if I return "&deg" the tooltip shows those 5 chars instead of the degrees mark(°).
    Same if I return "°"... tooltip shows those 6 chars instead of the degree mark.

  9. In order to display two panes (price pane at top and volume pane at bottom) correctly when chart's container resizing, it would allow to set axis's top and height at runtime.

    Or another way you can do is to set axis's top and height value in percentage unit.

  10. I noticed today that it seems the Y minor and major grid lines are drawn, and then the X minor and major grid lines. This causes X minor grid lines to be drawn over Y major grid lines, which I don't think should be the case. Here is an example:

  12. While Highcharts Stock supports dynamically updated data, the new data points are applied in a jerky fashion. It's becoming easier to build real-world real-time data applications: it'd be great if HighCharts Stock could handle these updates in a smoother fashion (similar to Smoothies http://joewalnes.com/2010/08/10/introducing-smoothie-charts/).

  13. The chart title is rendered behind chart data and grid lines, causing data points to obscure the chart title.

    When rendering to an interactive web page, it is possible to work around this by bringing the title toFront() after load.

    However, this is impossible when using export, since it creates a new copy of the chart and then exports that.

    Thus, the chart title should render in front of other chart elements, by default or as an option.

  14. Sometime there is a lot of category (x-axis) that can't fit inside the chart, so to solve this we can do:

    Rotate them, and/or
    Write some of the x-axis items according to the chart area size

  16. Currently I have an issue where if a set is empty, the line will still be displayed, and if all of the series are empty, a chart will display without any lines. This should be handled by default where if the series is empty, do not draw the line for it, and if all of the series are empty, do not draw the chart.

  18. Since now, if you want to specify X-axis origin for column chart, you can set offset value for X-axis. But this is not usable, the offset value is just absolute points, not actual Y value. I know many popular charts support using actual Y value as X-axis origin, this should be convenient for user to specify a relative X-axis location to Y axis.
