    Default ST2.1 RC2 additional series line at zero

    ST2.1 RC2 additional series line at zero


    When adding multiple series to a chart, I get an additional horizontal line at zero for each series with no points on it.
    In the image below there is actually three lines stacked horizontally on top of each other. This can be seen by disabling various series through the legend. The second image demonstrates this with just a single series left enabled.

    Is this a know bug?

    I'm not sure I full follow what you are saying. So you expect to have breaks in the line if they don't have points?

    the last charge demonstrates better with the orange line. there is one data series here yet there are two lines. the one with data points on it is the correct line. the horizontal line at zero is not one representative of my data and interestingly it has no markers either.

    Hmm... can I get a test case so I can look into why this is happening?

    this sample should repro the issue, however, I can't see the series rendered on there anyhow yet the scale on the axes is correct.

    Code:
     
     /**
     * Demonstrates how use Ext.chart.series.Line
     */
     
    Ext.define('Kitchensink.view.LineChart', {
        extend: 'Ext.Panel',
        requires: ['Ext.chart.Chart', 
            'Ext.chart.series.Line', 
            'Ext.chart.axis.Numeric', 
            'Ext.chart.axis.Time', 
            'Ext.chart.interactions.CrossZoom'],
        config: {
            cls: 'card1',

    I'm not seeing any line at zero (strange horizontal line at y=0) when I toggle a series. In RC2 the lines would not disappear but in our latest code that will be GA the lines are hiding properly. With your test case I cannot reproduce any unwanted behavior by toggling series.
