If you have markers set near your line, they will appear on the graph along with labels (if labels are turned on in Config.) Next to the various exportable formats is a collapse link that moves you back to the profile-only box. Pro, Desktop and Team accounts include an exportable elevation profile, as you see in the upper right corner of the statistic box. Within this, you can change the measurement frequency, export profiles, view markers that occur along the line if they are close enough, and view information about elevation, slope, aspect, tree cover, and land type that the line crosses. The sampling interval describes how often a point along the line is evaluated to be represented on the graph, and how much vertical distortion is displayed to aid in visualization of the elevation changes along the line. Next along the top of the profile box is the range of the highest and lowest elevation points along the line, followed by the total elevation gain and loss calculated along the line. The cursor reference tells you what distance from the beginning of your line that particular point is, and what the elevation of that particular point is. As you move your mouse cursor across the line within the profile box, a vertical black line represents where you are on the line and is paired with a red dot on the line in the map viewer. In the upper left of the profile box is a reference to the cursor. If you move along the elevation profile with your cursor, a small dot will appear on the map and show you exactly where that is on the map. Profile displays the change in elevation over the distance of the line. Save your changes to the line with the OK link in the edit box, or Cancel to discard your changes. When you edit a point in a line or polygon, a small undo box appears next to that point. You may need to zoom way in to see individual vertices when they are on top or near each other (see image below). You can change the setting for when the warning pops up so it only appears with a higher number of points, but this won’t change your browser’s ability to process all the points. To avoid this, you can use one of the tasks described below, such as resample or split the line, then edit it. You can risk it and edit anyway, but expect to wait extra time between changes or that the changes might pile up and not save. The reason for this is that having a lot of points can cause your browser to hang or perform poorly if they are all open for editing at once. If your line contains too many vertices, it will display a warning in the edit box telling you that the line has too many points to edit, or would you like to edit anyway. Click and hold the mouse pointer on a vertex, and drag it to a new location to change the alignment of your line. Each dot represents a vertex of the line. When the edit dialogue is open, you can also edit the points of the line on the map. If you want to change any of the line attributes, you can do so here. The edit box is the same as you worked with to draw the line. The edit link will open the edit panel for the line and show the vertices of the line.
