问题 i want to add many different markers on an android map. My code works good so far with the same overlay over and over again: mapOverlays = mapView.getOverlays(); drawable = this.getResources().getDrawable(R.drawable.marker); itemizedOverlay = new MyItemizedOverlay(drawable); OverlayItem overlayItem = new OverlayItem(geoPoint, "foo", "bar"); mapOverlays.add(itemizedOverlay); This works fine so far. But every marker is the same. What I want to do now is having different markers on the map like

问题 I am plotting Cumulative Distribution Functions, with a large number of data points. I am plotting a few lines on the same plot, which are identified with markers as it will be printed in black and white. What I would like are markers evenly spaced in the x-dimension. What I am getting is one marker per data point (and given the number of points, they all overlap) I'm not sure if it's my understanding of how to plot well, or just a lack of understanding matplotlib. I can't find a 'marker

How to set a fixed/static size of circle marker on a scatter plot?

我的梦境 提交于 2019-11-30 09:26:26
问题 I want to plot the location of some disks generated randomly on a scatter plot, and see whether the disks are 'connected' to each other. For this, I need to set the radius of each disk fixed/linked to the axis scale. The 's' parameter in the plt.scatter function uses points, so the size is not fixed relative to the axis. If I dynamically zoom into the plot, the scatter marker size remains constant on the plot and does not scale up with the axis. How do I set the radius so they have a definite

Issue on removing item from clustermanager

假装没事ソ 提交于 2019-11-30 07:10:37
问题 In my Android application, I have to delete and re-add a cluster item in my GoogleMap, that represents my current location. But when I run this code: clusterMng.remove(myitem); I get this Exception: java.lang.UnsupportedOperationException: NonHierarchicalDistanceBasedAlgorithm.remove not implemented. Can someone explain to me what this means? Do I have to rewrite some methods of ClusterManager.java in the external library? Or can I simply change my algorithm? 回答1: By default ClusterManager
