  4. I'm not sure if this is a big one or not, but I know that Android uses a form of WebKit for the built-in browser so it can't be too far removed from the iPhone / iPad

    NB - technically you can install Opera or another browser, but most people don't

  5. if you can add a button which allows user to toggle the legend the it will be great, because as of now if you are displaying the legend on chart area then some part of chart points get hidden because of legend, and user just cant see them because legend box is on top of the chart points.

    I even tried to do a normal toggle action with help of jquery but there are some issues when we do it. e.g. if we hide the legend and then add some series dynamically to chart then series gets added properly but…

  7. When hiding an Y-Axis (for example when using multiple Y-Axis), I'd suggest to remove the Y-Axis title as well. Yet only the axis disappears.

  8. Instead of setting the margins as an option, the required margin should be computed based on the size of the axis labels. Also add non-collision detection for category labels.

  9. Setting in what timezone dateTimeLabelFormats are displayed. There is already useUTC, but usually when you have market data the time zone is displayed as the time zone of that specific market. So if someone is in for example in italy looking at data from Brazil, it's suppose to see the time as in BRST (Brazilian standart time) and not the local time zone setted in their computer

    Implemented this option today. The new option, global.timezoneOffset, should be used when useUTC is true to change how dates are displayed and grouped on axes, data grouping and labels/tooltips etc. Please test the new feature with your own data and report back in this thread.

    The Highstock file can be loaded from http://github.highcharts.com/highstock.js.

    Demo cases:
    - http://jsfiddle.net/highcharts/y6Q7p/

  14. There should be drill down facility charts. If I have a pie chart in which I have two data "Desktop" and "Mobile". If I click on "Mobile" part in pie chart it should redirect to column graph or bar graph (whichever i specify) and list ll the mobile device I had used.

  16. We're working on implemening a server component that will take an SVG representation of the chart and convert it to raster or vector image formats using Batik. A preview can be seen at http://www.highcharts.com/demo/?prerelease=1.3 (the download icon at the top right).

  18. I'm aware that a similar idea has been completed (http://highcharts.uservoice.com/forums/55896-general/suggestions/1813731-hiding-of-y-axis), but what I'm asking for is different:

    There are a LOT of users asking for how to hide an axis completely:
    http://stackoverflow.com/questions/10877927/hide-axis-and-gridlines-highcharts
    http://stackoverflow.com/questions/15277405/highchart-show-hide-an-y-axis-without-hiding-the-series
    http://stackoverflow.com/questions/17409041/highcharts-hide-xaxis
    etc.

    Can we just have a property called "visible" on the Axis object that would show/hide the axis?

  20. My suggestion for a very helpful feature would be to add a vertical navigation bar for the Y-Axis, similar to the navigation bar that exists for the X-Axis, for Highcharts. Would lead to a highly interactive plot, especially suitable for project using scatter-plots
