2 issues using FastLineSeries

Hi,

Thanks FastLineSeries, my app is responding much quicker now.

Though, there are 2 issues:

  1.  It would bring many Range error on Line 264 of growable_array.dart, when I do single tap on the screen to show the TrackBar.

          the line content is: 

    external T operator [](int index);

    The errors:

    ════════ Exception caught by gesture library ═══════════════════════════════════

    RangeError (index): Invalid value: Not in inclusive range 0..514: 1144

    ═══════════════════════════════════════════════════════════════════════


    ════════ Exception caught by gesture library ═══════════════════════════════════

    RangeError (index): Invalid value: Not in inclusive range 0..300: 522

    ═══════════════════════════════════════════════════════════════════════


    ════════ Exception caught by gesture library ═══════════════════════════════════

    RangeError (index): Invalid value: Not in inclusive range 0..900: 946

    ═══════════════════════════════════════════════════════════════════════

    Most of these error happened with inclusive range being 0..514


    2.  I set the TrackBar to show the data of all 4 axises(

    tooltipDisplayMode:                TrackballDisplayMode.groupAllPoints,

    ), but now it shows data of 1 or 2 or 3 axises only, never 4.

    It always show 4 when using LineSeries.

Hi, Lavanya,


Thank you so much for the help and the kind welcome.

I'm trying lazy loading on smaller data sets now,  maybe later for FastLineSeries, to see which have better effect.


Best Regards,

Zhu
