Clustering options:- Show cluster cells:Shows rectangles around the cells used for clustering. This is only a visual aid to help you understand what the script is doing. - Clamp grid cells to lat/lon: If checked, cells will be relative to fixed lat/lon values. If unchecked, cells will be relative to the search area. The search area extends 256 pixels beyond the visible map in order to create a 'buffer zone' for quick panning. For this reason, some of the markers may fall outside of the visible map. - Center cluster marker on cell: If checked, each cluster marker is placed at the center of its cell. if unchecked, each cluster marker is placed at the average lat/lon for the properties in its cell, (like 'weight' or 'gravity'). - Max. markers: Limit number of properties. Below this number, properties are shown individually. Above this number properties are shown in clusters. - Grid units (degrees): Grid cell span in decimal degrees of latitude and longitude. Examples of valid values are 5, 2, 0.5, 0.1, etc.,or 'A' for automatic calculation. - Min per cluster: Minimum number of markers per cluster. If any one cluster contains fewer than this number it will be de-clustered into individual markers. The time shown above the map, under "query took: ..." is the net time that the MySQL server took to return the results of the query. The second time, (in parentheses), is the time it took to execute all queries, including the de-clustering queries. The difference between that time and the total loading time, depends on your internet connection and on how fast the browser can update the screen. Firefox is fast, Internet Explorer is slower. |
