    Default Time axes not working for Ext.chart.Chart

    Time axes not working for Ext.chart.Chart


    Hi everybody,

    I encouter somes troubles to do a chart with Time axes, When i set type of the bottom axes to 'Time', line does not appear, if i set it to 'Category' that's work, but i want this to Time type for scaling data because my X value does not have the same step.

    Anyone have an idea ?

    The code below can be run in a single html page.

    Thank for reading,
