“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 them in a constructor, method, initializer etc. I suggest you change your code to something like this: static Set<String> languages = getDefaultLanguages(); private static … Read more
Parameters in an SQL statement via ODBC are positional, and marked by a ?. Thus: # SQL with parameters start res = cursor.execute(”’ SELECT * FROM TABLE WHERE TABLE.TIMESTAMP BETWEEN ? AND ? ”’, STARTDATE, ENDDATE) # SQL with parameters stop Plus, it’s better to avoid passing dates as strings. Let pyodbc take care of … Read more
imagesc can put the png on you plot. We can avail ourselves of this in the following way: Define user data: x = 1:10; y = 5*rand(size(x)) + 2.5; Load the marker image: marker = imread(‘icon.png’); Define marker size and adjust the x and y data: markersize = [1,1]; %//The size of marker is expressed … Read more
Using several markers in a single scatter is currently not a feature matplotlib supports. There is however a feature request for this at https://github.com/matplotlib/matplotlib/issues/11155 It is of course possible to draw several scatters, one for each marker type. A different option is the one I proposed in the above thread, which is to set the … Read more
Nice find! The documentation doesn’t make things clear. Diving into the source code, leads to these lines in plot.py: for marker in parent.markers: # make a copy of the marker dictionary # so that it doesn’t get altered m = marker.copy() args = m.pop(‘args’) ax.plot(*args, **m) So, sympy just calls matplotlib’s plot with: the args … Read more
For solving this you need to understand equation of circle, which is something like this For any point (x,y) to fall within circle with center (x1, y1) and radius r units is (x-x1)^2 + (y – y1)^2 <= r^2 where a^b = a to the power b Here in your case User B’s (latitude, longitude) … Read more
Based on a clarification of the question, here’s an implementation of creating intermediary points along a <polyline> element such that the marker-mid=”url(#arrowhead)” attribute will work. See below that for an introduction to markers and arrowheads. Demo: http://jsfiddle.net/Zv57N/ midMarkers(document.querySelector(‘polyline’),6); // Given a polygon/polyline, create intermediary points along the // “straightaways” spaced no closer than `spacing` distance … Read more
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( “map”, “100%”, 400, initialTileLayer = “//{s}.tiles.mapbox.com/v3/jcheng.map-5ebohr46/{z}/{x}/{y}.png”, initialTileLayerAttribution = HTML(‘Maps by … Read more
The performance issue is due to the fact that each marker is an individual DOM element. Browsers struggle in rendering thousands of them. In your case, an easy workaround would be instead to use Circle Markers and have them rendered on a Canvas (e.g. using map preferCanvas option, or with a specific canvas renderer that … Read more
