    Default Any solution to get a discrete LineSeries (or something other), i.e. with gaps?

    Any solution to get a discrete LineSeries (or something other), i.e. with gaps?


    Hi,

    What if I need a gap within a LineSeries?

    I think LineSeries cannot be discrete. So, I am just asking - is there any solution? Sure, apart from two LineSeries for one gap, three LineSeries for two gaps, etc. I need just one Series, but with gaps.

    You can specify values of 'undefined' to halt the drawing of a line.

    Hi Scott,

    Thanks a lot for the answer.

    Previously I tried with nulls. But, anyways, I am not sure where I should specify 'undefined' to get a required gap.

    Please look at the screenshot. I need a gap between 25 and 75.
    2.JPG
    Here is a test case. Could you clarify, please, where should I specify 'undefined' to get a gap between 25 and 75?

    Test Case
    Code:
    <html>
    <head>
        <title>Chart Gaps</title>
    
        <link type="text/css" rel="stylesheet" href="../resources/css/ext-all.css" />
    
        <script type="text/javascript" src="../ext-all-debug.js"></script>
    
        <script type="text/javascript">
            Ext.onReady(function () {
                Ext.create("Ext.chart.Chart", {
                    renderTo: Ext.getBody(),
                    height: 400,
                    width: 400,
                    axes: [{
                        position: "bottom",
                        title: "X",
                        fields: ["x"],
                        type: "Numeric"
                    }, {
                        position: "left",

    My mistake.. It seems that undefined only works if it is at the end as shown:
    http://www.sencha.com/forum/showthread.php?233162

    If the values are in the middle, the markers are omitted and the line continues.

    You would most likely need to override or create a new series. I see there is a bug report for this:
    http://www.sencha.com/forum/showthread.php?179292

    It is slated for 4.2 release (no public date)

    Regards,
    Scott.

    Hi Scott,

    What about to have the same behavior for nulls? The nulls come from a server. Then we could avoid setting up a convert handler to get undefined instead of nulls.

    This is slated for 4.2. I have noted that you would like to have null as an option.

    Scott.

    Hi Scott,

    Re: LineSeries with gaps

    Someone found out that "false" as a value produces a gap. Here are more details and a working sample.
