Hi Hos,

Yes, you can remove the trendline icons from the legend in your scatterplot graph. Here are the steps to do so:

1. Click on the chart to select it.
2. Click on the "Chart Elements" button (the plus sign icon) that appears next to the chart.
3. Uncheck the box next to "Trendline" in the "Chart Elements" menu. This will remove the trendline icons from the legend.

Alternatively, you can also remove the trendline icons by modifying the legend entries manually. Here are the steps to do so:

1. Right-click on the legend and select "Select Data" from the menu.
2. In the "Select Data Source" dialog box, select the trendline series that you want to remove from the legend.
3. Click on the "Remove" button to delete the selected series from the legend.
4. Repeat steps 2-3 for any other trendline series that you want to remove from the legend.
5. Click "OK" to close the "Select Data Source" dialog box.
