Let us start by plotting the population of Australia over time. GOOG stands for Google, FB stands for Facebook, and AMZN stands for Amazon. For the pie, bar-like, sunburst and treemap traces, it is possible to force all the text labels to have the same size thanks to the uniformtext layout parameter. ; Standalone text annotations can be added to figures using fig.add_annotation(), with or without arrows, and they can be positioned . Absolute positioning is useful for trendline annotations which should continue to indicate the correct trend when zoomed. Determines whether or not the annotation is drawn with an arrow. Conclusion. How do I add annotations to a specific sub-plot in a figure in Julia Let us make some stacked bar charts. Let us consider a hypothetical scenario. In order for absolute positioning of the arrow to work, "axref" must be exactly the same as "xref", otherwise "axref" will revert to "pixel" (explained next). I just ran into a case where setting cliponaxis: false just wouldn't work. Here are several questions about it: The yaxis range is [0,5] and the xaxis range is [0,2]. Rather than the geometry of annotations, one is often interested in extracting the region of interest of the image delineated by the shape. But, in this section well use different type for x & y axes. Bubble charts are a great way to visualise data and understand insights. This tutorial shows how to annotate images with different drawing tools in plotly figures, and how to use such annotations in Dash apps. "x" or "x2"), the `x` position refers to a x coordinate. Shifts the position of the whole annotation and arrow to the right (positive) or left (negative) by this many pixels. Sets text to appear when hovering over this annotation. 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`. Determines whether or not the annotation is drawn with an arrow. This parameter gives options for the x-axis range: range_x=[, ]. Relative positioning is useful for specifying the text offset for an annotated point. Sets the width (in px) of the border enclosing the annotation `text`.
