I have a chart with 12 long legend names. Putting the legend on the right side will compromise the chart. Also I need the legend names be horizontal. Not all names on the vertical line it will be too long.
You can set the orientation of the legend by via orientation attribute in the legend attribute in the layout settings :. Default legend Horizontal legend. Learn more. Asked 3 years, 3 months ago.

Dark Mode Beta - help us root out low-contrast and un-converted bits. Related Hot Network Questions.I have a Dash app with plots different data depending on the value selected in a dropdown. In one set of data, the series names are longer so the legend automatically repositions itself into the plot area. This is until some minimum value is reached and plotly decides the legend should be superimposed on top of the plot area. I never want the legend super imposed and want to keep it on the right.
To solve this, ideally would be altering the minimum value rule I mentioned, or less ideally, by setting a fixed smaller size for the plot area to allow room to the right of the plot area for a legend with longer names. Is this possible? This will cause the left edge of the legend to always start just to the right of the end of the xaxis, thus keeping the legend out of the plotting area. BTW: There is no trace type named linewhat you want here is scatter. It just so happens that scatter is what Plotly.
Thanks for your reply and correcting line to scatter! Ok, I see what you mean. The textwrap module is really nice for this. Avoid legend automatically repositioning Graphing Library. I have produced a minimal dash app example below to demonstrate. Dash app. Div [ dcc. Hi maxwellTry setting the layout. Hope that helps! Hi jmmease Thanks for your reply and correcting line to scatter! See code below which produces the following: image.
Legend overlapping figure. Something like: import plotly.Documentation Help Center. For the labels, the legend uses the text from the DisplayName properties of the data series. If the DisplayName property is empty, then the legend uses a label of the form 'dataN'.
The legend automatically updates when you add or delete data series from the axes. This command creates a legend for the current axes or chart returned by gca.
If the current axes are empty, then the legend is empty. If axes do not exist, then this command creates them. Specify the labels as a list of character vectors or strings, such as legend 'Jan','Feb','Mar'. Specify subset as a vector of graphics objects. You can specify subset before specifying the labels or with no other input arguments. Specify the target as the first input argument. For example, 'Location','northeast' positions the legend in the upper right corner of the axes.
Specify the location after other input arguments. The default for ornt is 'vertical'which stacks the items vertically. The default for bkgd is 'boxon'which displays the legend background and outline. Use lgd to query and set properties of the legend after it is created.
For a list of properties, see Legend Properties. Plot two lines and add a legend to the current axes. Specify the legend labels as input arguments to the legend function. If you add or delete a data series from the axes, the legend updates accordingly. Control the label for the new data series by setting the DisplayName property as a name-value pair during creation. If you do not specify a label, then the legend uses a label of the form 'dataN'.
Note: If you do not want the legend to automatically update when data series are added to or removed from the axes, then set the AutoUpdate property of the legend to 'off'. Starting in Rb, you can display a tiling of plots using the tiledlayout and nexttile functions. Call the tiledlayout function to create a 2-by-1 tiled chart layout.
Call the nexttile function to create the axes objects ax1 and ax2. Plot random data in each axes. Add a legend to the upper plot by specifying ax1 as the first input argument to legend.
Plot two lines. Specify the legend labels during the plotting commands by setting the DisplayName property to the desired text. Then, add a legend. Plot four lines. Create a legend in the northwest area of the axes.
Specify the number of legend columns using the NumColumns property.
By default, the legend orders the items from top to bottom along each column. To order the items from left to right along each row instead, set the Orientation property to 'horizontal'. If you do not want to include all of the plotted graphics objects in the legend, then you can specify the graphics objects that you want to include.Every aspect of a plotly chart the colors, the grids, the data, and so on has a corresponding key-value attribute in these objects.
This page contains an extensive list of these attributes. Plotly's graph description places attributes into two categories: traces objects that describe a single series of data in a graph like Scatter or Heatmap and layout attributes that apply to the rest of the chart, like the titlexaxisor annotations.
Here is a simple example of a plotly chart inlined with links to each attribute's reference section. Figure [ go. Determines whether or not this trace is visible. If "legendonly", the trace is not drawn, but can appear as a legend item provided that the legend itself is visible. Sets the legend group for this trace. Determines the drawing mode for this scatter trace. Otherwise, "lines". Assigns id labels to each datum.

These ids for object constancy of data points during animation. Should be an array of strings, not numbers or any other type. Builds a linear space of x coordinates. Builds a linear space of y coordinates. Sets text elements associated with each x,y pair.
If a single string, the same string appears over all the data points. If an array of string, the items are mapped in order to the this trace's x,y coordinates.
Template string used for rendering the information text that appear on points. Sets hover text elements associated with each x,y pair. Determines which trace information appear on hover. Template string used for rendering the information that appear on hover box. Assigns extra meta information associated with this trace that can be used in various text attributes. Assigns extra data each datum. This may be useful when listening to hover, click and selection events.

I have been tweaking legends in plotly and R. One thing I am unable to figure out is how if it is possible to reposition legend items so that they are listed horizontally and centered below the plot.
The default legend items are positioned vertically and located to the right of the plot, as shown here:. However, I notice that this legend position changes based on how I view the plot the dimensions I make the plot window, etc. Because of this, the legend will sometimes accidentally overlap the plot by being positioned too high up or be separated from the plot by an awkwardly-large distance by being positioned too low.
Here is an example image of the legend being positioned too low:. Moreover, when placing the legend below the plot, it may look better to have legend items listed horizontally instead of vertically.
In this example, it would be great to have virginica, versicolor, and setosa listed left to right in the legend instead of top to bottom.
Hence, ideally looking like this:. Is it possible to obtain this - that is, a legend positioned centered and below the plot that does not change location with window size while listing its items horizontally?
According to documentation the following should do the trick:. It sets the legend orientation to "horizontal", then sets the anchor point which position we specify to the center of the legend, and then positions it in the middle of the x-axis.
Which results in the following graph:. Learn more. Asked 3 years, 6 months ago. Active 1 year, 2 months ago. Viewed 10k times.

If NULL default value of this option will not be changed. If "normal", the items are displayed top-to-bottom in the same order as the input data. If "reversed", the items are displayed in the opposite order as "normal".
If "grouped", the items are displayed in groups when a trace 'legendgroup' is provided. Described in R plotly reference. Legend's background color. Legend's font color. Legend's x position.

In my case, I used the event to manually render the legend svg last because I wanted it to display above annotations. I know that this issue is pretty old but if I want to have legends tooltip on two different graphs on the same page, how does that work. Is there any an example in angular 5 I am doing this way: Plotly.
I have all the data getting from back end in this. But not sure where to add Plotly. Hi Etienne, I am using the code you have suggest. Its working fine when there is one graph in the page. But I have 2 graphs and both of them different attach property.
Hi Etienne, its not working. Its working but if we mouse over on the bottom graph the top one is also showing the tool tip. Can we get it independently. Like if we mouse over on the bottom graph only its tool tip needs to be shown.
