    Default No-Chart-Data into jfree Component

    hi to all
    is it possible to hide a generic component subsequently to a specif event?
    For example, hide a jFreeComponent when query result are without data.
    Another: is it possible, like pentaho report designer, show a label " no chart data" ?

    If you're talking about xaction graphs, I think you can use an If step with a condition like
    Code:
    If query_result.getRowCount() > 0
    then you build the graph, otherwise you skip it.

    If you have no xaction, directly inside the dashboard you may use some javascript trick like
    Code:
    postExecution: function() {
    if (something)
    document.getElementById(html_element).style.display = "none";
    }
    Of course that "something" needs to be defined somehow.
