Syncing zoom across several date-based serial charts #74

Hi,

Nice package you put together. I use it a lot.

I'm trying to replicate the JS example in https://www.amcharts.com/kbase/syncing-zoom-across-several-date-based-serial-charts/ using listeners in rAmChart but I've not been able to get it to work after several trials. I added the JS below to my existing serial charts per your suggestion in http://datastorm-open.github.io/introduction_ramcharts/advance.html but nothing happened. Could you please tell me what I'm doing wrong. I'm not familiar with JS so this might be something simple that I'm missing.

addListener(name = "syncZoom", expression = paste("for (var x in charts) {
                                                    charts[x].addListener("zoomed", syncZoom);
                                                    charts[x].addListener("init", addCursorListeners);
                                                    }

                                                    function addCursorListeners(event) {
                                                    event.chart.chartCursor.addListener("changed", handleCursorChange);
                                                    event.chart.chartCursor.addListener("onHideCursor", handleHideCursor);
                                                    }

                                                    function syncZoom(event) {
                                                    for (x in charts) {
                                                    if (charts[x].ignoreZoom) {
                                                    charts[x].ignoreZoom = false;
                                                    }
                                                    if (event.chart != charts[x]) {
                                                    charts[x].ignoreZoom = true;
                                                    charts[x].zoomToDates(event.startDate, event.endDate);
                                                    }
                                                    }
                                                    }

                                                    function handleCursorChange(event) {
                                                    for (var x in charts) {
                                                    if (event.chart != charts[x]) {
                                                    charts[x].chartCursor.syncWithCursor(event.chart.chartCursor);
                                                    }
                                                    }
                                                    }

                                                    function handleHideCursor() {
                                                    for (var x in charts) {
                                                    if (charts[x].chartCursor.hideCursor) {
                                                    charts[x].chartCursor.forceShow = false;
                                                    charts[x].chartCursor.hideCursor(false);
                                                    }
                                                    }
                                                    }"))

Thank you.

Hi,

It's possible with ?amTimeSeries using group parameter
