You will also learn How data visualization increases interactivity. Toggle this annotation when clicking a data point whose `x` value is `xclick` rather than the annotation's `x` value. By default uses either dark grey or white, for maximum contrast with `hoverlabel.bgcolor`. If set to a x axis ID followed by "domain" (separated by a space), the position behaves like for "paper", but refers to the distance in fractions of the domain length from the left of the domain of that axis: e.g., "x2 domain" refers to the domain of the second x axis and a x position of 0.5 refers to the point between the left and the right of the domain of the second x axis. By default uses the annotation's `bgcolor` made opaque, or white if it was transparent. Time series data, mathematical functions, etc., are some of the data which can be plotted using Line Plots. But opting out of some of these cookies may affect your browsing experience. Shifts the position of the whole annotation and arrow up (positive) or down (negative) by this many pixels. Many data visualizations help in determining frequency. Is there a way to move them below the trace layer but above the shape layer? The advent of computers and displays meant that data could be processed and presented efficiently. If `ayref` is not `pixel` and is exactly the same as `yref`, this is an absolute value on that axis, like `y`, specified in the same coordinates as `yref`.
