Hi Peter,

thanks for your great help with my thread before : drop_down_list so select different metrics.
Iam on it but I didnt find my error, yet.


Now I found out that I have another problem with the Time Remaining and realtime Update function from the this sample code:

function updateDisplay()
{
    // Utility to get an object by id that works with most browsers
    var getObj = function(id) {    return document.getElementById ? document.getElementById(id) : document.all[id]; }

    // Get the configured update period
    var updatePeriodObj = getObj("UpdatePeriod");
    var updatePeriod = parseInt(updatePeriodObj.value);

    // Subtract 1 second for the remaining time - reload the counter if remaining time is 0
    if (!updatePeriodObj.timeLeft || (updatePeriodObj.timeLeft <= 0))
        updatePeriodObj.timeLeft = updatePeriod - 1;
    else
        updatePeriodObj.timeLeft = Math.min(updatePeriod, updatePeriodObj.timeLeft) - 1;

    // Update the chart if configured time has elasped
    if ((updatePeriodObj.timeLeft <= 0) && window.JsChartViewer)
        JsChartViewer.get('ChartImage1').partialUpdate();

    // Update the display to show remaining time
    getObj("TimeRemaining").innerHTML = updatePeriodObj.timeLeft + ((updatePeriodObj.timeLeft > 1) ? " seconds" : " second");
}




I want to use it to update it in my graphs from Zooming-Scrolling Demonstration.
I dont know what I have to change that it works. :(

There is no chart Image like "ChartImage1" in Zooming Scrolling Demonstration.
There are functions for partial Update, fullUpdate and in the html code is this:

                <!-- ****** Here is the chart image ****** -->
                %(viewer.renderHTML())s


How can I combine this methods?
I want that the Chart Image is being updated when the time is elapsed.

Brgds

Sorry that I created this thread.

I came to the clue that it makes no sense to include the UpdatePeriod in the script.

If you want to have the current data, I can use the Pointer as well.
Because my query looks like :

between now() and now-30days....I always get the current data points.

I decided to seperate it into 2 scripts.
