Scatter chart in Dashboard


We have created a scatter chart in 3 different panels in the same dashboard, when we save the dashboard, after sometime when we open the dashboard and refresh, the settings in the last panel which was saved is reflecting to all the panels. Is there any setting to change at dashboard level, so that the changes or setting for each panel will be different from other

What do you use to create the scatter plot? I have not found a way to do that without installing a plugin.

We have installed plugin for scatter chart and later we have designed the dashboards
