  Update the FullChart
Posted by Gilles on Nov-07-2016 09:15
HI Peter

I use zoomscrolltrackweb for have only the graph that I want with checkbox, and I have put the WebViewPortControl object of viewportcontroldemoweb.php

The chart is update for the checkbox cheked but not the FullChart (the view port control).
Can you say me how I can update it.

Thank you very much
Gilles


Here is the script:


//
// Execute the following initialization code after the web page is loaded
//
JsChartViewer.addEventListener(window, 'load', function() {


    // Update the chart when the view port has changed (eg. when the user zooms in using the mouse)
    var viewer = JsChartViewer.get('<?php echo $viewer->getId()?>');
    viewer.attachHandler("ViewPortChanged", viewer.partialUpdate);

    // Initialize the navigation pad
    JsViewPortControl.get('<?php echo $viewPortCtrl->getId()?>').setViewer(viewer);

    // Draw track cursor when mouse is moving over plotarea or if the chart updates
    viewer.attachHandler(["MouseMovePlotArea", "TouchStartPlotArea", "TouchMovePlotArea", "PostUpdate",
        "Now", "ChartMove"], function(e) {
        this.preventDefault(e);   // Prevent the browser from using touch events for other actions
        trackLineLegend(viewer, viewer.getPlotAreaMouseX());
    });

    // The Update Chart can also trigger a view port changed event to update the chart.
    document.getElementById("SubmitButton").onclick = function() { viewer.raiseViewPortChangedEvent(); return false; };

    // Before sending the update request to the server, we include the state of the check boxes as custom
    // attributes. The server side charting code will use these attributes to decide the data sets to draw.
    viewer.attachHandler("PreUpdate", function() {
        var checkBoxes = ["data0CheckBox", "data1CheckBox", "data2CheckBox", "data3CheckBox"];
        for (var i = 0; i < checkBoxes.length; ++i)
            viewer.setCustomAttr(checkBoxes[i], document.getElementById(checkBoxes[i]).checked ? "T" : "F");
    });

    // Draw track cursor when mouse is moving over plotarea or if the chart updates
    viewer.attachHandler(["MouseMovePlotArea", "TouchStartPlotArea", "TouchMovePlotArea", "PostUpdate",
        "Now", "ChartMove"], function(e) {
        this.preventDefault(e);   // Prevent the browser from using touch events for other actions
        trackLineLegend(viewer, viewer.getPlotAreaMouseX());
    });
});

//
// Draw track line with legend
//
function trackLineLegend(viewer, mouseX)
{
    // Remove all previously drawn tracking object
    viewer.hideObj("all");

    // The chart and its plot area
    var c = viewer.getChart();
    var plotArea = c.getPlotArea();

    // Get the data x-value that is nearest to the mouse, and find its pixel coordinate.
    var xValue = c.getNearestXValue(mouseX);
    var xCoor = c.getXCoor(xValue);
    if (xCoor == null)
        return;

    // Draw a vertical track line at the x-position
    viewer.drawVLine("trackLine", xCoor, plotArea.getTopY(), plotArea.getBottomY(), "black 1px dotted");

    // Array to hold the legend entries
    var legendEntries = [];

    // Iterate through all layers to build the legend array
    for (var i = 0; i < c.getLayerCount(); ++i)
    {
        var layer = c.getLayerByZ(i);

        // The data array index of the x-value
        var xIndex = layer.getXIndexOf(xValue);

        // Iterate through all the data sets in the layer
        for (var j = 0; j < layer.getDataSetCount(); ++j)
        {
            var dataSet = layer.getDataSetByZ(j);

            // We are only interested in visible data sets with names, as they are required for legend entries.
            var dataName = dataSet.getDataName();
            var color = dataSet.getDataColor();
            if ((!dataName) || (color == null))
                continue;

            // Build the legend entry, consist of a colored square box, the name and the data value.
            var dataValue = dataSet.getValue(xIndex);
            legendEntries.push("<nobr>" + viewer.htmlRect(7, 7, color) + " " + dataName + ": " +
                ((dataValue == null) ? "N/A" : dataValue.toPrecision(4)) + viewer.htmlRect(20, 0) + "</nobr> ");

            // Draw a track dot for data points within the plot area
            var yCoor = c.getYCoor(dataSet.getPosition(xIndex), dataSet.getUseYAxis());
            if ((yCoor != null) && (yCoor >= plotArea.getTopY()) && (yCoor <= plotArea.getBottomY()))
            {
                viewer.showTextBox("dataPoint" + i + "_" + j, xCoor, yCoor, JsChartViewer.Center,
                    viewer.htmlRect(7, 7, color));
            }
        }
    }

    // Create the legend by joining the legend entries.
    var legend = "<nobr>[" + c.xAxis().getFormattedLabel(xValue, "mm/dd/yyyy") + "]" + viewer.htmlRect(20, 0) +
        "</nobr> " + legendEntries.reverse().join("");

    // Display the legend on the top of the plot area
    viewer.showTextBox("legend", plotArea.getLeftX(), plotArea.getTopY(), JsChartViewer.BottomLeft, legend,
        "width:" + plotArea.getWidth() + "px;font:bold 11px Arial;padding:3px;-webkit-text-size-adjust:100%;");

    // Set the view port width to represent the required duration (as a ratio to the total x-range)
    viewer.setViewPortWidth(Math.min(1,
        duration / (viewer.getValueAtViewPort("x", 1) - viewer.getValueAtViewPort("x", 0))));

    // Set the view port left so that the view port is moved to show the latest data
    viewer.setViewPortLeft(1 - viewer.getViewPortWidth());

    // Trigger a view port change event
    viewer.raiseViewPortChangedEvent();

Hi Gilles,

You would need to update the main chart as well as the full chart. I have created an example for your reference.

Hope this can help.

Hi Peter,

I have try your code and it work well but the chart don't update its timeline but the fullchart update timeline. so there is a gap between the two time lines if you wait a little time.

I have put for you a picture of the gap after waiting around 18hours and push button id="SubmitButton"
I have also put my code if you want see it.

Do you think it's possible to update the two charts?

Thank you very much.
Gilles

  Re: Update the FullChart
Posted by Peter Kwan on Nov-11-2016 03:11
Hi Gilles,

In your code, the full data range can change at any moment, but it calls setFullRange in initViewer, which is only run during initialization. So the main chart will not know the full range have been updated. However, the full chart always plots all the data so it always reflect the updated full range. The main chart and the full chart therefore become inconsistent.

To address this issue, please move the setFullRange code from initViewer to the drawChart function so that the main chart would know the most updated full range.


function initViewer(&$viewer) {
    //Pour récupérer le creneau que l'on a dans la base
    global $nbLigne;

    # Initialize the view port to show the last 366 days (out of 1826 days)
    #Initialise le graph sur une largeur de 180 données parmis toutes les données
    $viewer->setViewPortWidth(180 / $nbLigne);
    $viewer->setViewPortLeft(1 - $viewer->getViewPortWidth());

    # Set the maximum zoom to 10 days (out of 1826 days)
    # Défini le zoom maximum 1 donnée parmis toutes les données
    $viewer->setZoomInWidthLimit(1 / $nbLigne);
}


function drawChart(&$viewer)
{
     global $dateMini;

     //construction de la période en fonction des données que l'on à dans la base
    $startAnnee = date('Y', $dateMini);
    $startMois = date('m', $dateMini);
    $startJour = date('d', $dateMini);
    $startHeure = date('H', $dateMini);
    $startMinute = date('i', $dateMini);
    $startSeconde = date('s', $dateMini);

    # The full x-axis range is from Jan 1, 2007 to Jan 1, 2012
    $startDate = chartTime($startAnnee, $startMois, $startJour, $startHeure, $startMinute, $startSeconde);
    $endDate = chartTime(date('Y'),date('m'),date('d'), date('H'), date('i'), date('s'));
    $viewer->setFullRange("x", $startDate, $endDate);

    ......
    ......

}

I noticed that even for regular update (such as for zoom in), the full range would have changed, and you would need to update both the main chart and the full chart to make them consistent. I suggest you can change the window.load event handler below to ensure both charts always update together:

//
// Execute the following initialization code after the web page is loaded
//
JsChartViewer.addEventListener(window, 'load', function() {

    // Update the chart when the view port has changed (eg. when the user zooms in using the mouse)
    var viewer = JsChartViewer.get('<?php echo $viewer->getId()?>');
    var vpViewer = JsChartViewer.get('<?php echo $viewPortCtrl->getId()?>');

    // Update the main will also update the full chart
    viewer.attachHandler("ViewPortChanged", function() {
        viewer.partialUpdate();
        vpViewer.partialUpdate();
    });

    // Initialize the navigation pad
    JsViewPortControl.get('<?php echo $viewPortCtrl->getId()?>').setViewer(viewer);

    // The Update Chart can also trigger a view port changed event to update the chart.
    document.getElementById("SubmitButton").onclick = function() {
        viewer.raiseViewPortChangedEvent();
        return false;
    };

    // Before sending the update request to the server, we include the state of the check boxes as custom
    // attributes. The server side charting code will use these attributes to decide the data sets to draw.
    viewer.attachHandler("PreUpdate", function() {
        var checkBoxes = ["data0CheckBox", "data1CheckBox", "data2CheckBox", "data3CheckBox", "data4CheckBox", "data5CheckBox", "data6CheckBox", "data7CheckBox", "data8CheckBox", "data9CheckBox", "data10CheckBox", "data11CheckBox", "data12CheckBox", "data13CheckBox"];
        for (var i = 0; i < checkBoxes.length; ++i)
{
            viewer.setCustomAttr(checkBoxes[i], document.getElementById(checkBoxes[i]).checked ? "T" : "F");
            vpViewer.setCustomAttr(checkBoxes[i], document.getElementById(checkBoxes[i]).checked ? "T" : "F");
}
    });

    // Draw track cursor when mouse is moving over plotarea or if the chart updates
    viewer.attachHandler(["MouseMovePlotArea", "TouchStartPlotArea", "TouchMovePlotArea", "PostUpdate",
        "Now", "ChartMove"], function(e) {
        this.preventDefault(e);   // Prevent the browser from using touch events for other actions
        trackLineLegend(viewer, viewer.getPlotAreaMouseX());
    });
});


Hope this can help.
