Following the example given in the legend guide, you can use a Line2D object instead of a marker object. The only difference to the example given in the guide is you want to set linestyle=”None” import matplotlib.lines as mlines import matplotlib.pyplot as plt blue_star = mlines.Line2D([], [], color=”blue”, marker=”*”, linestyle=”None”, markersize=10, label=”Blue stars”) red_square = … 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
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 can use L.LatLngBounds in order to create an area to zoom to. First, create a bounds and pass it an array of L.LatLngs: var bounds = new L.LatLngBounds(arrayOfLatLngs); This will create a bounds that will encapsulate every point that is contained in the array. Once you have the bounds, you can fit the bounds … Read more
You can use markeredgewidth (or mew). You’ll want to combine it with markersize, otherwise you get thick but tiny markers. For example: plt.plot([2,4,6,1,3,5], ‘+’, mew=10, ms=20)
First, as @darioo said: MDC is used for associating multiple events with few “entities” [Markers] are used for “special” events that you want to have filtered from usual ones So your assertion that You want to use MDC for this. Markers are for highlighting “special” events–filtering, if you will–rather than “slicing”. For example, you might … Read more
