can't unregister click event in openlayers

由 僤鯓⒐⒋嵵緔 提交于 2020-01-13 19:24:07
问题 I am having issues with OpenLayers and unregistering the click events that are added to a layer. Basically, what I need to do is this: When a user clicks on a marker, they get a bubble that has an "edit" link in it. The user clicks that and it creates a new layer on the map and then registers a click event to the map waiting for the user to click on the map. When they click somewhere on the map, it then moves the marker to where they clicked. This all works perfectly. However, the issue is

How to set the radius of a circle marker to be proportional to an attribute value?

由 天大地大妈咪最大 提交于 2020-01-11 14:31:07
问题 So I am making a Leaflet map. I am using a json which lists countries as Latlng points, and their corresponding attribute (called CTH values). I am trying to use this value to set the radius of circle markers on these Latlng points, but I am struggling to figure out how. This is what I've written function addCTHValueMarkers () { CTHValueLayer = L.geoJSON(CTHValue, { pointToLayer: function (feature, latlng) { return new L.circleMarker(latlng, { fillOpacity: 0.6, radius: setRadius(feature

JFreeChart BarChart - Category Markers

由 此生再无相见时 提交于 2020-01-05 03:31:47
问题 I'm creating a BarChart that contains multiple frequency bands as the category axis. What I want to do is to show a visible grouping of these frequency bands: For example: Freq x1 ~ Freq x2 = Band y (so the domain axis has values for category x1, x1.1, x1.2 till x2) Freq x3 ~ Freq x4 = Band z (x3, x3.1 .....x4) What I want to do is show markers for Band Y and Band Z in the graph. Note that based on the dataset that I may get, not all categories may be present. Say, for the 1st example, I've

Leaflet JS + Leaflet.Deflate - Changing default marker icon to custom icon

由 时间秒杀一切 提交于 2019-12-25 08:36:21
问题 In my previous post 'Leaflet JS - changing esri shape into marker on certain zoom level ' I was able to resolve an issue which i had with the leaflet JS library and changing the polygon shapes to markers icons when hitting a certain zoom level. I was advised by 'Ivan Sanchez' to use the 'Leaflet.Deflate' plugin and this works like a charm, so now the various shapes are being transformed into markers after a certain zoomlevel, however now I'm struggling to change the default leaflet marker

问题 I am working on ECG signal processing. I am using the MIT-BIH Arrhythmia database found here. After loading the signal, I marked the R peaks correctly. Then I was trying to extract QRS complex, but I couldn't. I want to make marks on peaks like in this image: . . . . . . . Here is my code: clear all; clc; close all; load ('G:\1.Thesis\data set\100\100m') %% Remove base & gain %%figure (1) val = (val - 1024)/200; ECGsignal = val(1,1:3600); SAMPLES2READ = 3600; time = (0:length(ECGsignal)-1)
