markers

So I have a MapView with a lot of markers, most of which are concentrated in mile wide clusters. When zoomed the markers overlap and appear to only be one. What I want to achieve is at a certain zoom level replace the overlapping markers with a group marker that will display the density of markers and onClick will zoom to display all markers inside. I know I can do this with brute force distance measurements but there must be a more efficient way. Anyone have any solution or smart algorithms on how I can achieve this? Um... assuming the markers are not grouped, layered or anything: why -

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 semantic context into the logging - e.g. while a class may be handling multiple concerns, one may use task

I am trying to use sets in the following way: static Set<String> languages = new HashSet<String>(); languages.add("en"); languages.add("de"); And I get the following error message generated by Eclipse: > Multiple markers at this line > - Syntax error on token ""en"", delete this token > - Syntax error on token(s), misplaced construct(s) I cannot figure out what I am doing wrong. Can anybody please help me? "Multiple markers" just means "there's more than one thing wrong with this line". But the basic problem is that you're trying to insert statements directly into a class, rather than having

I'm trying to denote the predictions with a color and the correct labels as markers for the iris data set. Here is what I have so far: from sklearn.mixture import GMM import pandas as pd from sklearn import datasets import matplotlib.pyplot as plt import itertools iris = datasets.load_iris() x = iris.data y = iris.target gmm = GMM(n_components=3).fit(x) labels = gmm.predict(x) fig, axes = plt.subplots(4, 4) Superman = iris.feature_names markers = ["o" , "s" , "D"] Mi=[] for i in range(150): Mi.append(markers[y[i]]) for i in range(4): for j in range(4): if(i != j): axes[i, j].scatter(x[:, i], x

I have searched google and everyone says its not supported. I was wondering if there are any open community matlab functions which would be able to plot a user defined png as a marker. The closest I found was http://de.mathworks.com/matlabcentral/fileexchange/39487-custom-marker-plot/content/plotCustMark/plotCustMark.m . But it doesn't serve the intended purpose . Let me know if its even possible for me to write something up for this ! Thanks. Additional Problem : Okay I have this weird problem now . my png has a black background !! I dont understand why. I tried to lower the alpha value still

How can I receive a mouse click event on a marker in a leaflet map in R? I'm using the RStudio/leaflet and running through Shiny. I'd like to get the value of a marker (e.g., ID) and use that to update a sidebarPanel. SamanthaDS You want to use input$MAPID_marker_click . See the example below. library(shiny) library(leaflet) latitude <- c(35.94077, 35.83770, 35.84545, 35.81584, 35.79387, 36.05600) longitude <- c(-78.58010, -78.78084, -78.72444, -78.62568, -78.64262, -78.67600) radius<-c(15, 12, 12, 12, 12, 15) ids<-c("a", "b", "c", "d", "e", "f") shinyApp( ui = fluidPage( fluidRow( leafletMap(
