Can I change the marker type for a line series using Report Designer?

We wish to use a triangle and a circle in a Line Graph to graph points for 2 series. Currently, all values in the chart are graphed using a box shape. We need to better distinguish the different values in the series. We changed the series palette, but we need to additionally allow each series to have it's unique marker shape.

Is it possible to change the Line Chart's Marker Type for a series in the Report Designer?

Hi cantyman,

Please see the attached screenshot.

This is a built-in feature to the designer. Inside the Chart Wizard, go to the format chart tab. From there select "Value (Y) Series". Click the button toward the bottom of the window called "Markers". From here a smaller window will pop out to the right of the wizard. Add as many different markers as you need here. The engine will then use these markers in building out the chart; one per series. This window will even allow you add external images that can be used to serve as markers on your chart if you so need.

See attached sample for more context.

Good Luck!

Thanks for the help! It worked. I'll try to ask harder questions next time.

Is it possible to change the shape or visibility of a series marker dynamically? What I want to do is show a circular marker only if there is one data point, else show no markers at all.
Thanks in advance.

Hi its_pi,

You can set the visibility of the marker to false with this script:

function beforeDrawMarker( marker, dph, icsc )
{
marker.setVisible(false);
}
