Is it possible to limit zoom level for chart?


In old version (Classic) there was some limit in zooming. I think based on data resolution level. In new version I could zoom to any level,
even without good connection lines and without axis labels on this level.

Is it possible to somehow reproduce old behavior and limit available zoom level? In old version it shows ""XZoomFactor or YZoomFactor is not inside the limit of zooming"

Hi Yauhen,

Thanks for contacting Syncfusion support. We have analyzed your query. For limiting zooming action we have written following code in preRender and zoomed event.

function prerender(args) {

            pxZoomfactor = args.model.primaryXAxis.zoomFactor;

            pyZoomfactor = args.model.primaryYAxis.zoomFactor;

            pxzoomposition = args.model.primaryXAxis.zoomPosition;

            pyzoompostion = args.model.primaryYAxis.zoomPosition;

function zoomed(args) {

        if (args.model.primaryXAxis.zoomFactor == pxZoomfactor && args.model.primaryXAxis.zoomPosition == pxzoomposition) {

            isZoomed = true;


            setTimeout(function () {

                $("#annotation_Container_annotation_0").css("display", "none");

                isZoomed = false;


            }, 3000);



In “preRender” event, we have simply get the zoomposition and zoomfactor for both of the axis. In “zoomed” event, we have compared the zoomfactor and zoomposition with previous zoomfactor and zoomposition stored in the prerender event. If these are same, then zoomfactor of the chart is getting lesser than 0.001. In this case we have displayed the text “Minimum zooming value reached” inside the chart using annotation. Please find the below screenshots.

Second time zooming the chart.
