To create diamond markers instead of bubbles, use the SeriesList's Markers property to define the type of marker used. You can choose from Circle, Tri, InvertedTri, Box, Diamond or Cross.

This topic illustrates how to change marker type in Design view and in Source view.

Changing the Marker Type in Design View:

To change the marker type of your C1BubbleChart, follow these steps:

1. Click C1BubbleChart's smart tag to open the C1BubbleChart Tasks menu.
2. Click the SeriesList item. The BubbleChartSeries Collection Editor appears.
3. Select the series from the Members list that you wish to change its marker type. In this example we'll select the first series from the Members list.
   
4. Select the dropdown arrow next to the Type and then choose Diamond.
5. Cick OK.

The Diamond marker type is applied to the first bubble chart series.
