When I apply the cross marker type to a scatter plot, it’s not centered correctly. It gets more off-center the thicker the stroke becomes. This tends to be the case for any mark that uses the strokeStyle parameter.
This is actually visible in the example app under “Using PointMarkers”. In the attached screenshot of the example app, I increased the cross marker thickness to 15 to show how off-center the cross is to the line. This becomes a bigger issue in a scatter series as there’s no line to reference of where the point should actually be.
Hopefully there’s a way to fix this, but if not, any help on how to apply a corrective offset would be great.
Thanks in advance for any guidance!
Is it possible to plot a continuous vertical line as part of data point markers in line graph? I have used sprite to render text for data points. Now I want to draw a vertical line starting from data point till the peak apex to show which peak it is pointing to. The text labels in point markers are shifted to upward for some peaks to avoid collision and therefore there is a gap between peak apex and the point marker. So this requirement. I tried so far with OR symbol but it is displayed as a vertical dotted line when multiple OR symbols are placed one below another.
We have included in our wpf chart vertical slices to show markers on data series, but when a vertical slice is added, one marker per series is shown at the same time.
Is it possible to show only one marker per series and per vertical line annotation? We want to add serveral vertical slices, and each one has a marker to only one series.
Please find attached two pictures: the first one represents what we have, and the second one represents what we need.
Thank you in advance
I have multiple dataseries of around 20,000 points each, and the calculation of each point originates from one of three sources. I would like to show, for each point, a different data point marker depending on the origin of the point. Each point marker should also show some meta data about the calculation origin in a tooltip when it is moused over.
I have been able to achieve this effect using the Annotations API, as shown here: http://s4.postimg.org/otgc4yk3x/markers.png but chart performance grinds to a halt with an AnnotationCollection of up to 100,000 annotations attached to the surface.
Can I show this information in another way that will be performant, taking advantage of virtualisation, efficient algorithms on sorted data etc.? I was thinking that I may be able to add the point origins as metadata to the XyDataSeries, benefit from the performance optimisations that come with a SciChart series, and show the metadata in DataPointMarkers with tooltips? Could this work? Can I also have a differently shaped datapoint marker for each point depending on the metadata?
