ChartEventMarker not cleared after first pass of sweep line

Post by mattmobilemedtek » Mon Feb 09, 2015 7:46 pm

Hello,

I'm displaying a ChartEventMarker on a graph with a SampleDataSeries. The graph's XAxisScrollMode is set to Sweeping. When I add a new ChartEventMarker, while graphing, the marker is on top of the graph data when initially displayed. After the sweep line passes it over the first time, the graph data is displayed over the ChartEventMarker. Once the sweep line passes it over again, the ChartEventMarker is erased.

I was expecting it to be cleared after the first pass since it's XValue has been passed. Is this fixed in the newest version? I'm using version 6.3.2.

Thanks,
Matt

I was incorrect about the behavior. It actually does the following.

1. I add a ChartEventMarker at a point in time, 8 seconds for example
2. The graph data is behind the ChartEventMarker in z-order
3. The sweep wraps around and passes over the ChartEventMarker, this paints the graph data over the marker, but the marker is still visible
4. The sweep line gets to the end of the current visible range and then the ChartEventMarker is removed.

Is there a way to fix this?

Hi Matt,

you are correct, it doesn't work similar to SeriesEventMarkers in this regard.

We'll try to come up with a solution to next week's release.

I just installed version 6.4.1 and it looks like it's fixed. Thanks for taking care of that so quickly!
