Hi,
We are implementing Time slider programmaticaly (for the reasons we cannot customize the standard one according to requirements).
app.currentTimeSeriesLayer = initialised earlier and added to map// visible on the map
function MyTimeSliderRun()
{
var timeIntervalMilliSeconds = 5000;
var startYear = 1995;
var endYear = 2016;
var Years = endYear - startYear;
var increment = 0;
for (i = 0; i <= Years; i++) {
setTimeout(function () {
var layerDefinitionsTS = [];
app.currentTimeSeriesLayer.setLayerDefinitions(null, true);
var curYear = startYear + increment;
increment = increment + 1;
layerDefinitionsTS[app.currentTimeSeriesLayer.visibleLayers[0]] = "Year = " + curYear;
app.currentTimeSeriesLayer.setLayerDefinitions(layerDefinitionsTS, false);
}, timeIntervalMilliSeconds*i);
}
We cannot see the layer on the map, what is a possible reason?
