    Default Unanswered: 2.1 Charts crash iPad 3, not iPad Mini -- can we disable retina?

    Unanswered: 2.1 Charts crash iPad 3, not iPad Mini -- can we disable retina?


    Seeing 100% repeatable crash with Charts 2.1 on an iPad 3 after adding two simple gauge charts to one tab and a simple line chart with 3 series to another tab.

    Interestingly, it does NOT crash an iPad mini fresh out of a box. Surprising as there is only 512MB in the mini and 1GB in the iPad 3. I suspect this is related to charts using retina, as the same charts do NOT crash the iPad 3 under charts 2.0.

    Thoughts? What I really want is to disable retina in charts. Possible?

    I have a demo next week so a bit worried about this.

    Default Forcing non-retina works for me

    Forcing non-retina works for me


    Update:

    changing line 96 of src/draw/Surface.js from:

    Code:
    devicePixelRatio: window.devicePixelRatio,
    to

    Code:
    devicePixelRatio: 1,
    helps the crashing issue for me. Charts are, of course, less sharp, but it helps. Still crashes on rotation, if I use the legend to hide and show a series multiple times, or if I go back and forth between bottom tabs with charts on them. It feels as if each time I go back and forth, another copy of the chart is loaded....

    The really strange thing is, on the iPad mini, everything is silky smooth. Can't get it to crash. Seems faster too.

    Default Disabling tab panel animation also helps

    Disabling tab panel animation also helps


    This seems to have helped greatly as well:

    Code:
     layout: {
                animation: false
            },
    Now I can switch tab panel buttons between charts endlessly on the iPad 3 without issue.
