    Default Problem in ScatterChart

    Hi!

    I am using scatter chart by using Sencha Touch 2.1
    I am facing below mention two issue:
    1). Inside ItemInfo interaction, Im using listeners where Im using show event
    show: function (me, item, panel, eOpts){}
    My problem is that Im not able to get item whose info is being displayed.
    When Im print it as: console.log(item);
    Its showing as HTMLCanvasElement
    Plz tell me in what way I can get the item, because I need the record which should be inside item.
    Even I have not find item record in me,panel.


    2). Im using legend, but not getting the corresponding colors basically it should be corresponding the color of charts.

    Below are the code for reference:
    Scatter Charts code:

    Code:
    Ext.define('BenefitAccess.view.StockPlanChart', {
    Code:
        extend: 'Ext.Panel',
        alias: 'widget.StockPlanChart',
        requires: ['Ext.chart.Chart', 'Ext.chart.series.Scatter', 'Ext.chart.axis.Numeric'],
        config: {
            id: 'StockPlanChart',
            cls: 'card1',
            layout: 'fit',
            items: [
                {
                    xtype: 'toolbar',
                    margin:'0 0 20 0',
                    docked: 'bottom',
                    items: [
                        {
                            xtype: 'spacer'
                        },
                    ]
                },
                {

                    console.log('insideeee');
                    console.log(item);
                    panel.setStyle('background:'+item.sprite.attr.fillStyle);
                    if(item.record.data.name=='Order')
            panel.setHtml('<font color="white">'+'<ul><li><b>Order: </b>' + item.storeItem.get('Order') + '</li>');

            var toolbar = Ext.ComponentQuery.query('toolbar', this)[0],
                interaction = Ext.ComponentQuery.query('interaction', this)[0];
            if (toolbar && interaction && !interaction.isMultiTouch()) {
                toolbar.add(interaction.getModeToggleButton());
            }
        }
    });


    For reference also attaching image where can see exact problem in legend, where can easily see the color of Legends come in black. Basically it should be like respective charts color.

    1. The problem is that you are using 'tap' instead of 'itemtap'.

    2. I have added a fix for the legend color issue and it will be in the next release.
