markers

问题 Is there a way through the android maps API, where I can detect the map center after pan animation has completed? I want to use this information to load markers from a server dynamically. Thanks BD 回答1: I also have been looking for a "did end drag" solution that detects the map center at the moment exactly after the map ended moving. I haven't found it, so I've made this simple implementation that did work fine: private class MyMapView extends MapView { private GeoPoint lastMapCenter; private

问题 We are using SLF4J+Logback combination at our project for a while now and are quite happy with it, but our logging strategy is fairly simple, using straightforward class based loggers and no fancy stuff like MDC or Markers. What I want to know is if anybody in the community actually uses these features and how they are used to improve logging/filtering. I am specially interested in where, why and how would one use [1] Markers for logging. They strike me as a pretty neat feature for adding

问题 Given the following: import matplotlib.pyplot as plt import numpy as np #http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.scatter x = np.random.randn(60) y = np.random.randn(60) x2 = np.random.randn(60) y2 = np.random.randn(60) plt.plot(x, y, marker='o', markeredgecolor='r', linestyle='none', markerfacecolor='none') plt.plot(x2, y2, marker='o', markeredgecolor='r', linestyle='none', markerfacecolor='none') plt.show() I'd like for x2 and y2 to be plotted as dashed (or even dotted)

问题 Given the following: import matplotlib.pyplot as plt import numpy as np x = np.random.randn(60) y = np.random.randn(60) x2 = np.random.randn(60) y2 = np.random.randn(60) plt.scatter(x, y, s=80, facecolors='none', edgecolors='r') plt.scatter(x2, y2, s=80, facecolors='none', edgecolors='r') plt.show() How would I plot this same data with dashed circles instead (where the outline of each circle is dashed instead of solid) for x 2 and y2 only? Thanks in advance! Update: I know this can be done

问题 In programs and IDEs, I've seen options to show different markers. It tends to be spaces, but Word shines more light on this with more markers to show. I was wondering if showing markers like this were possible in Tkinter with the Text widget. I have a link from the Word help file to explain a little more what I'm looking for. https://support.content.office.net/en-us/media/f5cc9771-1070-4ebf-bd7a-4d3dc245966f.png I was thinking that I could do this with tags and a for loop, but I was

问题 I seem to be having a problem with associating a problem marker with a resource; in my case, I'm trying to create a problem marker for the editor. To achieve this, I've tried to do the following: public class MyEditor extends TextEditor{ private ColorManager colorManager; public MyEditor() { super(); ... IResource resource = (IResource) getEditorInput().getAdapter(IResource.class); try { marker = resource.createMarker(IMarker.PROBLEM); } catch (CoreException e) { e.printStackTrace(); } }

问题 Forget everything until here, I spent the dawn trying, to see if I could move forward, I'll explain. I have a map and I need to enumerate the 1 to 15 markings. The markings are correct, the problem that marks only 1, 15 times. This is my json: https://github.com/eltonsantos/analise_integrada/blob/master/path.js simple json, nothing much My code is: var rotas = L.geoJSON(paradas, { onEachFeature: onEachFeature, pointToLayer: function(feature, latlng){ console.log("Qtd: " + paradas.features

问题 Hello Stack Overflow community, I am a Java newbie and I am doing a simple java project where I take coordinates (lat and lon) from a (dynamic) source and use JMapViewer (Yes, not JXMapViewer) to display the markers on a map. I have put all the coordinates in two ArrayList(s). It looks like that: for(int i = 0; i < latArrayList.size(); i++){ map.addMapMarker(new MapMarkerDot((double)latArrayList.get(i), (double)longArrayList.get(i))); } EDIT: map is a jMapViewer object. And it works pretty

问题 I am creating a site that uses a database in the background to track markers on a javascript google maps api. For some reason when I log in to my site and it redirects to the maps page it will load the map but no markers. Then if I refresh, the markers will show up. I didn't have the problem before until I moved it to a different site but all of the links work so it isn't a problem with links as far as I can tell. Code is below...kinda messy so I apologize. <?php session_start(); if(!session

问题 I am having 'similar' issues to Matplotlib, legend with multiple different markers with one label. I was able to achieve the following thanks to this question Combine two Pyplot patches for legend. fig = pylab.figure() figlegend = pylab.figure(figsize=(3,2)) ax = fig.add_subplot(111) point1 = ax.scatter(range(3), range(1,4), 250, marker=ur'$\u2640$', label = 'S', edgecolor = 'green') point2 = ax.scatter(range(3), range(2,5), 250, marker=ur'$\u2640$', label = 'I', edgecolor = 'red') point3 =
