Zoom Slider Not Working in Online Service

Hi mathiasrh - The issue with the Zoom slider not working online in Power BI but working in Power BI Desktop can occur due to differences in feature support between the two environments.

The Zoom slider feature is generally supported in both Power BI Desktop and Power BI Service, but it may not display correctly if the report has a lot of data or if the feature has not been enabled in the Power BI Service version you’re using. Double-check that the Zoom slider option is enabled in your report settings under the Format pane in Power BI Desktop before publishing to the Service.

Large datasets or complex visuals may sometimes cause performance issues in Power BI Service, which could affect the interactivity of features like the Zoom slider. Try reducing the data shown in the chart (such as by applying filters) to see if the slider becomes responsive.
